Solutions for Formulating Low VOC Water based Gloss Trim Paints using Binders with Structured Particle Morphology
Author: Brown JOSEPH Compliance with the increasingly stringent VOC regulations is a major challenge for paint formulation chemists today - especially when it comes to gloss paints, where traditionally solvent borne alkyds are used. This paper describes water borne acrylic binder technology using a structured particle morphology in combination with an ambient cross linking mechanism, which provides a solution to the coatings manufacturer challenge to achieve high performance environmentally friendly water borne gloss coatings, without compromising the performance and application properties typically linked to conventional solvent based alkyd coatings.
This paper discusses the impact of the polymer composition on the film formation and the block resistance and how the structured particle morphology and ambient cross-linking enables the formulation of a trim paint with an optimized balance of gloss, block, and adhesion without incorporating co-solvents.

Next generation environmentally friendly surfactants for architectural paint applications
Author: Dr.Luis MADRIGAL Advanced design techniques have led to the development of novel surfactants which enable the coatings industry to comply with existing and upcoming EU regulations, without compromising coating performance. EU Directives have increased regulation on raw materials for paint and coating applications. In the case of surfactants, the requirement is for both products with excellent performance and also having low VOC contents, biodegradable and label free. This paper describes Dow’s development of a new surfactant based on an alkoxylated secondary alcohol. The project focused on the need for a product with equivalent or better dispersing properties than traditional APE based products. High through-put testing accelerated the identification of synergistic effects between the alcohol moiety and the EO, PO and BO alkoxylated chains. The new family of surfactants was evaluated in various decorative paint formulations and demonstrated excellent dispersant performance, low foaming, stability, optical properties, and mechanical properties.

A Newly-introduced, Low Odor Amino Alcohol that Helps Enable European Architectural Paint Producers to meet 2010 VOC Requirements
Author: Emmanuelle YVON Meeting 2010 VOC paint limitations, such as those set in EU Directive 2004/42/EC, can present a challenge for paint producers, especially in terms of product performance. Amino-methyl-propanol (AMP) has a well established history of providing key multifunctional benefits to paint formulations, including neutralizing and dispersion properties, but is classified as a VOC. The necessity for a non-VOC amino alcohol has led to the development of an improved version of amino-ethyl-propan-diol (AEPD). This amino alcohol is a primary amine with improved color and odor properties, low vapor pressure, a high boiling point, a non-yellowing characteristic and is a classified as VOC-free in Europe. Additionally, this new version of AEPD offers the same excellent performance benefits as AMP in terms of co-dispersion efficiency, neutralization, scrub resistance and color stability with the added benefit of an improved odor profile, making it a clear choice as a multifunctional amine for VOC-free paints. Although similar in structure to AMP, an additional hydroxyl function in AEPD allows for an extension in the open time without impairing the scrub resistance. Additionally, AEPD has been shown to have significant coalescent properties allowing for reduction in primary coalescent levels and other VOC materials. About Emmanuelle YVON

Accelerated Aging of Thermoset Coatings below their Glass Transition Temperature
Author: Fabio AGUIRRE The service life of polymers is often predicted by extrapolation from accelerated aging tests. High temperatures are typically employed to accelerate the aging. This approach assumes the aging mechanism is the same in the accelerated tests as it is for the lower service temperature. If the use temperature for a thermoset coating is near its glass transition (Tg), accelerating the aging via temperature will require testing above Tg. Diffusion rates of polymeric chain segments and many small molecules decrease very rapidly upon cooling through the Tg. Thus the validity of a temperature derived extrapolation that traverses the Tg is in question. Our approach for oxidative aging processes is to accelerate the oxidation using increased oxygen concentration allowing data collection in a reasonable time below Tg. This could prove a more valid method to predict service life of polymers in high service temperature applications. About Fabio AGUIRRE

High Performance Water Borne Polyurethane Dispersions based on Natural Oil Polyols for Wood Coating Applications
Author: Dr. Emile Trottier Aliphatic polyester polyols have been produced from seed oil with high renewable content and unique properties that enable the formulation of water borne coatings with low volatile organic compounds (VOC) content. Water borne polyurethane dispersions (PUDs) with excellent stability and differentiated properties were developed from anionically stabilized prepolymers of aliphatic isocyanates and natural oil polyols (NOP). The performance of the NOP based PUD was compared to an adipate based PUD and a caprolactone based PUD made with the same formulation and to commercial polyester and polycarbonate PUDs used in wood coatings. The developmental NOP based PUDs are N-methylpyrrolidone (NMP) free and provide coatings with good mechanical properties including hardness and flexibility. They also exhibit superior performance attributes including water and acid etch resistance compared to conventional PUDs. The high contact angle for water supports the increased hydrophobicity of the NOP PUD coating. Fundamental material science and microscopy results clearly demonstrate phase separated morphology with micro-phase separated domains resulting from immiscibility of soft and hard blocks in the NOP PUD, while considerable phase mixing was observed in the conventional PUDs. The NOP PUD exhibits differentiated performance on specific wood coating application tests in comparison to commercial polyester and polycarbonate PUDs widely used in wood coatings, both as a neat dispersion and with an external crosslinker and in blends with a hydrophobic acrylic latex.

Advanced Technologies for the Formulation of Higher Performance Waterborne Masonry Coatings with Lower Environmental Impact. Pure waterborne acrylic technology is known to provide superior exterior durability to coatings for different substrates. Today's formulating tools can further improve this performance and also lower the environmental impact of the paint. Film integrity and adhesion to the substrate are essential for a protective coating. An optimum distribution of organic and mineral phases in the film can be obtained by encapsulating individual pigment particles with latex particles. This Pigment Encapsulation Technology (PET) allows the formation of polymer-pigment composite particles. Masonry paints based on PET binders exhibit strong adhesion to mineral substrates resulting in an improved efflorescence resistance. Replacing part of the TiO2 with an Opacifying Polymer (OP) improves the dirt pick up resistance. The homogeneous, spherical, hydrophobic OP resists dirt pick-up and helps reduce mold and algae growth. Additionally an optimized combination of a PET binder with an OP leads to paints with an even more favorable lifecycle analysis. About Dr. Marie Bleuzen

Designed Diffusion: A paradigm shift in film formation (awarded best paper) In latex based coatings, volatile organic compounds (VOC) are used as coalescents to ensure film formation. It has become increasingly difficult to maintain hardness, block, print and dirt pick-up resistance in industrial coatings as formulators reduce VOCs to meet demanding environmental regulations. Traditional methods of Tg reduction – latex morphology control and hard-soft blends – have been unable to meet the needs of the industrial coatings formulator... In this talk, a new technology is presented that significantly improves the early property development of waterborne latex coatings while addressing the challenges of the low VOC formulation landscape. This new Designed Diffusion technology balances coatings properties through careful design of the polymer system and the selection of a coalescent package with unique partition coefficient and diffusion rate between different phases of the polymer system. This paper presents detailed evidence of this DESIGNED DIFFUSION technology with analytical, physical and application data. About Dr. Zhenwen Fu

Next Generation Opaque Polymer Technology and Its Application to Alkyd Paints Since its introduction over 25 years ago, opaque polymer (OP) technology has undergone significant improvements thanks to continuous research and development efforts. This work allowed an unrivalled understanding of the principle of hiding technology and in the design of polymer particles and their process to ensure consistent high quality production. Today, many paint formulators are using opaque polymer not only to lower formulation cost, by reducing TiO2 usage, but also to improve paint properties such as hiding, exterior durability, brightness, scrub resistance, etc. OP has become a standard raw material used in the formulation of waterborne paint for both interior and exterior applications. Further developments in OP technology and formulation know-how now permit the creation of alkyd-based paints which incorporate the benefits and advantages of using OP. This paper will discuss the next step in OP technology and how alkyd paint formulators can use it to create new cost-performance balances. About CV Alain Garzon

Low Odour in paints: what does it mean and how can it be managed While more and more reduced odour paints continue to proliferate throughout the global market, there is much confusion over how to measure, manage and communicate this attribute. Methods to reliably and quantitatively measure the odour intensity and pleasantness of commercial low odour paints from around the globe are presented. Using gas chromatography the volatiles from these paints are easily defined and then additional analytical methods are presented that determine a relative contribution of each of the odourants. The data provides further confirmation that in near zero VOC paints odour is no longer driven by the large VOC contributors but rather by trace compounds. This linking of individual odourants and their concentrations with the perceived odour of the paint is key towards developing sustainable solutions that manage their odour. About Paul Doll

New Primal™ HG-1000 with new Hydrotech™ technology: low VOC gloss coatings-advances in performance and sustainability.
Dr Anne Koller Despite tightening VOC regulations, solvent-borne alkyds remain popular in Europe due to certain key properties like extended open time, superb flow and levelling and high potential gloss. They have deficiencies however such as relatively poor durability, film yellowing and solvent odour as well as an unfavourable environmental health and safety profile. Here we present an alternative to solvent alkyds - a new technology platform featuring a waterborne acrylic hybrid polymer dispersion for low VOC decorative coatings. This technology is suitable for high gloss paints and delivers significant improvements in flow and leveling and open time. These improvements are achieved through the choice of the polymer design of the hybrid and an alkyd like rheology. The new dispersion maintains the desirable dry film properties of pure acrylic systems, notably little or no yellowing and does not require the use of cobalt driers to develop its dry film properties.

Rheology in Coatings – Typical Problems and Practical Solutions, by Rohm and Haas.
Alain Garzon Formulating water based paints can sometimes be very challenging in respect to the desired wet paint properties but also to the application characteristics and behaviour. Although used at rather low levels in a formulation, the choice of Rheology Modifiers, and that of dispersing agent, may induce undesired issues for the formulator. Some basic interactions among the various paint ingredients are worth considering when formulating a water based paint. These interactions could be critical for viscosity adjustment, but also for the stability of the paint formulation, potentially contributing to poor thickening response, viscosity change, syneresis, etc. Rheology Modifiers are key for the application behaviour of a formulated paint. The right choice and levels have to be used to ensure the right in-can appearance, spreading characteristics, and flow and sagging properties balance. Rohm and Haas offer a wide range of Acrysol™ Rheology Modifiers designed to overcome the rheology problems paint formulators may encounter, either at the formulating or at the application stages.

Enabling technologies for the coatings industry: sustainability is profitability.
Dr Andrew Trapani The key business drivers of any successful company in the future have to encompass sustainable development criteria. Such criteria put a focus on sustainable growth – sustainable competitive advantage leading to sustainable earning power. Sustainability as a concept becomes a founding principle for continuous improvement, leading to either evolutionary or revolutionary innovations. This presentation will focus on methodologies for coatings products and integrates sustainable development criteria across the product life cycle, from conception through to recycling and the waste management phase. The resulting metrics allow a quantification of an individual product's overall eco-impact, carbon footprint and VOC emissions as well as reductions in energy & raw material consumption. We demonstrate that the sustainable development approach is a holistic, cross-disciplinary approach, necessarily involving functions across the organisation. It covers the whole value chain, and allows for the mapping of the carbon footprint of individual products, as well as for the identification of financial, operational and carbon-saving opportunities. We share some examples of our enabling technologies that allow paint formulators to create innovative products that combine high performance with an optimised eco-design. These technologies include: Organic opacifiers to replace titanium dioxide, advanced waterborne polymers with pigment encapsulation capabilities, waterborne polymers that dry quickly in all weather conditions, waterborne, hybrid polymers that allow for high gloss, low VOC coatings formulations.

Advances in high performance binders in architectural binders: latest innovations from Rohm and Haas.
Dr Marie Bleuzen Pure waterborne acrylic technology is known to provide superior exterior durability to coatings for different substrates. Film integrity and adhesion to the substrate are essential for a protective coating. An optimum distribution of organic and mineral phases in the film can be obtained by encapsulating individual pigment particles with latex particles. This Pigment Encapsulation Technology commercialized under the name Avanse™ technology, allows the formation of polymer-pigment composite particles. Masonry paints based on Avanse™ binder exhibit strong adhesion to mineral substrates resulting in an improved efflorescence resistance. We will also touch on new technology for higher performance interior architectural coatings. For interior paints, durability and performance are often measured via stain resistance. Rohm and Haas has recently commercialized a special product, Primal™ SG-380, which has a unique composition and self-crosslinking functionality that allow it to be used in easily cleanable, stain resistant paints. This gives the formulator a new tool for designing high quality, interior satin paints for the professional or DIY market. Paper 15:
A new generation of Rohm and Haas EIFS products.
Dr. Guy Clamen Rohm and Haas has developed a range of products for EIFS applications addressing the main needs of modern EIFS systems in terms of dirt pick-up resistance , durability, flexibility,… through a number of new binders and additives. These new binders were designed using powerful and modern polymer building blocks and functionalities to generate the performance and properties meeting the most demanding EIFS requirements while at the same time allowing the development of very low VOC formulations. These new polymers are particularly well suited to a wide range of finishes such as organic and inorganic types. This range of binders lists a specific grade addressing the specific needs of winter application conditions and allowing the extension of the application seasonal range. Finally new formulating additives were developed that ideally combine with above binders to deliver the most efficient dirt pick-up resistance properties and long lasting façade aesthetics. Paper 16:
New family of products containing Avanse™ technology - for use in broad range of industrial applications, notably metal and wood.
Tiziano Ferrari As environmental regulations become increasingly strict, manufacturers and end-users of metal and wood coatings find themselves under increasing pressure to make and use paints with more advanced environmental profiles, such as those with lower volatile organic compounds (VOC) content. Resin suppliers are challenged to design binders which not only allow lower VOC levels, but also maintain the expected high performance of traditional systems. Recent advances in designing waterborne acrylic dispersion polymers have lead to the commercialization of binders that are capable of encapsulating pigments and other minerals in a paint formulation. This new class of waterborne binders is particularly helpful in designing pigmented industrial coatings to be used in many different applications for the protection of a variety of metal and wooden substrates. The pigment-encapsulating binder technology allows for improvements in the overall environmental profile of the coating while providing the requisite level of protection and improved aesthetic durability.
