(1) Temporary release agent
During the working of the release agent, part of the release agent component is gradually consumed, that is, the release agent is transferred to the product during the molding process of the rubber and plastic products, and the release agent is called a temporary release agent, or It is called a migration release agent. A silicone release agent based on various inert silicone oils is a typical migration release agent. The temporary release agent is applied once or once for a limited number of times.

(2) Semi-permanent release agent
If the film layer after the mold release agent is cured adheres to the surface of the mold more firmly, the mold release agent component is not transferred to the product during the processing and molding process of the product, and the mold release agent is not consumed, and the mold release agent is called It is a semi-permanent release agent, or a non-migratory release agent. A silicone release agent based on a crosslinkable and curable silicone resin is a non-migratory release agent. The component of the release agent will not be transferred to the rubber and plastic products, and will not affect the subsequent processing such as the rough coating of the formed rubber and plastic products.
