Moisture-hardening one-component polyurethane paints for coating elastomeric parts, consisting of polyfunctional isocyanate compounds, solvents and, optionally, auxiliaries and/or coupling agents, which contain reactive polysiloxanes and reactive surfactants for improving surface slip, may be applied by a simple painting process to elastomers, particularly apolar elastomers, for example based on styrene-butadiene rubber or polyethylene-propylene-diene and, after drying, have an optically smooth surface with good surface-slip properties with respect to glass and no abrasive effect.

Anti-friction paint for elastomeric parts

An aqueous solution of suspension of glycidoxypropyl silanol and polydimethyl siloxanes having a number average molecular wieght of more than 100,000 and their use as mold release agents with good release values over a relatively large number of molding cycles in the molding of rubber and plastics.

Glycidoxypropyl silanol and polydimethyl siloxanes as mold release agents

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.

Aminohydroxy fatty acid amides obtained by condensation from epoxidized fatty acid alkyl esters and polyfunctional aliphatic oligoamines may be employed as crosslinking agents for polyfunctional epoxide compounds used as adhesives and/or coating compositions. The preferred crosslinking agent represents the reaction product of
