A method of manufacturing a composite insert includes forming a polymer mold from a polymer sheet which may have a glass transition temperature of 70 to 160° C., the polymer mold either includes a cavity or may form a cavity disposed between the polymer mold and the carrier. The method proceeds by depositing a liquid reactive composite insert composition, which may be a two-component composition including a first part comprised of an isocyanate-epoxy blend and a second part comprised of an alcohol-epoxy blend, into the cavity under low pressure conditions of 0-10 bar and low temperature conditions of 15-100° C. The composition is then allowed to become dimensionally stable either within the polymer mold or between the polymer mold and the carrier.

Method of manufacturing a composite insert

The subject matter is a new composition comprising at least one hydroxyl-group containing resin, at least one nitroso-containing compound or at least one nitroso precursor compound, at least one blocked isocyanate and at least one crystallization germ suitable as primer or coating for rubber to substrate bonding, which provides a scratch resistant surface, when applied, and excellent adhesion and steam resistance for rubber to substrate bonds. These compositions can especially be used as one coat systems.
