Rohm and Haas recently announced that it has received confirmation from ICC Evaluation Services that its Mor-Melt™ R-5022 hot melt adhesive complies with all applicable provisions of the 2003 International Building Code® (IBC), 2003 International Residential Code® (IRC), and 1997 Uniform Building Code® (UBC). This confirmation, as evidenced in the ICC-ES evaluation report ESR-2158, provides guidance to code officials faced with approving the use of Mor-Melt R-5022 under these codes. The full evaluation report is available online at http://www.icc-es.org/reports/pdf_files/ICC-ES/ESR-2158.pdf.

Company spokesperson Larry Salcedo, commercial manager, Structural Adhesives, North America stated, “By offering this first ICC-listed reactive hot melt adhesive for panel lamination, Rohm and Haas is able to assure top bonding performance for continuous laminating technology for manufacturers of structural panels. Users expect batch-to-batch formulation consistency with this moisture-curing polyurethane reactive hot melt adhesive.” Beta-tests have confirmed excellent bonding with facings of plywood, OSB, primed aluminum and steel, wood, FRP, and cores of expanded and extruded polystyrene, as well as polyisocyanurate foam and paper honeycomb.

Mor-Melt™ adhesives are produced as 100% solids, one-component urethane adhesives and are available in easy-to-store and handle 5-gallon pails and 55-gallon drums. They can be applied via roll coater or bead extrusion systems engineered for handling polyurethane reactive hot melt adhesives. Compared to other adhesive technologies, bond strength develops very quickly, thereby allowing for higher manufacturing throughput and reduced cost.

Mor-Melt™ R-5022 adhesive is available throughout North America. To obtain samples for evaluation or to speak with Rohm and Haas technical support specialists, email AandSe-Center@rohmhaas.com.
