Silicone Resins

Polydimethylsiloxane has been used as a release agent for various kinds of materials, such as plastics, metals, ceramics, etc. However, they have the disadvantage of being 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 to choose the right silicone resin with the right guide formulation. Many of the polydimethylsiloxane mold release compositions are not stable, particularly at high temperatures. Although this problem has been considerably reduced with the formulation, 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 different types of solvents, which may be used as a mold release agent.

Mold release processes that require high temperatures are shoe sole mold, aluminum dies casting mold, rubber mold release. Latro Kimya offers specific solutions and provide custom made formulations and raw materials for all these processes.

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 features to your products by using different resin derivatives and creating a formulation with our most accurate raw materials.
