Abstract
A moisture-hardening flocking adhesive composition for application to elastomers. The adhesive contains an isocyanate terminated polyurethane prepolymer, an aromatic dinitroso compound and an essentially hydroxyl-free epoxy resin having an epoxide value of from about 0.45 to about 0.75. The composition is essentially free of highly volatile organic solvents. The composition is characterized as having improved storage stability and provides excellent adhesion between elastomeric substrates and flocking fibers, even after exposure to water.
