Mold Release Agent

A mold release agent is an interfacial coating applied between two surfaces that would normally stick together. It causes the surfaces to separate cleanly, smoothly, and easily. Mold releases are needed for a variety of molding operations, such as castings, foam man­ufacture, injection molding and etc. Molding conditions such as mold material, cycle time and temperature must be consid­ered. The properties of the mold release must be matched to the molding conditions. Mold release agents are classified into two kinds: external mold release and internal mold release. The compositions of external mold release agents are various blends of natural and synthetic waxes. In addition to microcrystalline and/or polyethylene wax, some proprietary release agent compositions contain other additives including silicone oils. The mold release (sometimes called wax) is best applied by spray coating the mold. The usual release agents are microcrystalline waxes dispersed in sol­vents.
