Correct choice of release agent

Hits: 833 img

Silicone release agents include different forms and multiple dosage forms, which are suitable for different types of materials and different processing techniques. According to the working temperature, peeling force, and the subsequent surface finish of the product, choose the most suitable release agent.

On the corrosion-resistant substrates such as glass and ceramics, it is possible to apply the initially reacted corrosive organochlorosilane as the base material for the release agent. For rapid injection molding of multiple small pieces of small products, it is advisable to use aerosol-type silicone release agent; for large-scale hot mold processing products, water emulsion type silicone release agent can be used; cold mold processing technology is applied. It is not advisable to use a water-based release agent such as an emulsion, because moisture retention on the surface of the mold will affect the molding accuracy of the product, such as

It takes a long time to carry out the molding process after the water is evaporated, so the cold mold processing rubber and plastic products should adopt the solution type release agent with faster solvent evaporation to save the drying waiting time of the release agent.

For the release of the rubber and plastic products that emphasize the requirement of the non-migration coating, it is necessary to use a non-migratory silicone release agent, and no migration release agent is used to prevent the release agent component from migrating to the surface of the product and hinder the coating. In comparison with the release force, it is generally easier to carry out the partial migration of the release agent than the operation of the release agent-free component, that is, the release of the former is easier.
