ABSTRACT:
An environmentally preferred flock adhesive composition containing low molecular weight prepolymers of isocyanate terminated polyether and/or polyalkadiene polyols is disclosed. The prepolymers are free of residual volatile isocyanate (<1000 ppm) without blocking the isocyanate thereby providing favorable effects on viscosity, cure kinetics, and safety. The flock adhesive composition preferably contains an aromatic nitroso compound an epoxy novolak resin and a catalyst. The adhesive compositions can be made at high solids, with minimal co-solvent, while maintaining low viscosity, which is favorable to environmental regulations aimed at reducing solvent emissions. Furthermore, the solvents can be non-HAP and non-photochemically reactive. The adhesive composition can be utilized for the application of flocking fibers to various elastomer substrates.
