The use methods and effects of different types of silicone release agents of different shapes are different. The application method of the bulk silicone oil type and the aerosol type release agent is the most convenient, as long as the release agent is simply brushed or sprayed on the surface of the mold, the molding operation of the plastic product can be performed, and the release of the product is simple; but once or limited After the number of times of demolding, it is necessary to repeatedly apply the release agent. The application of the ointment type release agent is relatively complicated compared to the simple application of the solution release agent, but the ointment type release agent forms a working film layer thick and can be applied to a mold having a rough surface while being sustainable and effective. The number of demouldings is relatively high. Compared with the solution type silicone release agent, the water emulsion type silicone release agent has no pollution to the environment because no organic solvent is used. However, in comparison with the ease of demolding of rubber and plastic parts, the peeling force of the aqueous emulsion type release agent is relatively large, and the number of times of continuous demolding is also less than that of the solution type.
