Polydimethylsiloxane has been used as release agents for various kinds of materials, such as plastics, metals, ceramics, and the like. However, the heretofore polydimethylsiloxane release agents have the disadvantage that they are easily removed from the surface of the mold when subjected to abrasion. Although this phenomenon is not a problem in some applications, in others where abrasion is substantial, it poses a very serious problem. The abrasion may be attributed in part to the relatively low cohesive strength of the release coating and in part to the fact that there is less adhesion to the base member than is often desired. This combination of factors often causes excessive abrasion of the film during use, which results in bare spots on the base member with attendant sticking.
The main point is that choosing the right silicone resin with the exact guide formulations. Many of the polydimethylsiloxane mold release compositions are not stable, particularly at high temperatures. Although this problem has been considerably reduced with the recipe, it still presents significant difficulties in connection with using these compositions as mold release agents. Consequently, there is a great need for a stable, readily dispersible material in types of solvent which may be used as mold release agents.
Mold release processes that require high temperatures are such as shoe sole mold, aluminum dies casting mold, rubber mold release. All of the processes we have our solution and we give made tailor raw materials and recipes.
The most important point is process conditions, temperature, pressure, number of laps, type of mold, molding time, type of material to be molded, mold release application method, etc.
In line with this information, we add value and feature to your products by making use of different resin derivatives and creating a recipe with our most accurate raw materials.
