Abstract Mold release agents and means for their application are provided. The release agents are used in coating molds for forming expandible plastics. They are especially applicable to polyurethane-based reaction injection molding (RIM) systems. The release agents, which have a controlled saponified fatty acid content (unsaturated as oleate and/or linoleate and saturated as C8 to C12 alkanoate) make for significant advantage with respect to ease of release, prevention of residual build-up, mold and part cleanability, health and safety, cost, etc.
