Application of release agent for hot press

In the molding process, in addition to using internal release agents, external release agents are also applied on the surface of the mold cavity. Commonly used are oleic acid, paraffin, stearic acid, zinc stearate, silicone oil, and silicone grease. And silicone rubber, etc. Under the premise of meeting the requirements of demolding, the amount of release agent applied should be as small as possible, and the application should be even. Under normal circumstances, phenolic moulding materials mostly use release agents such as organic oil, oleic acid and stearic acid, epoxy or epoxy phenolic moulding materials are mostly silicone grease and silicone oil release agents, and polyester moulding materials are mostly hard fat. Release agents such as zinc acid and silicone grease.
