Mosites #14287 silicone compound is a high hardness formulation that is sold in an uncured calendered sheet form. It is unusual that it can be co-cured in contact with typical epoxy prepeg reinforcements to fabricate stiff pressure distribution pads or caul plates. Since it is a silicone-based product it has excellent handling and lay-up characteristics, and after vulcanization, it has natural release properties from accidental or intentional contact with epoxy resin. This release can be improved by the application of approved release agents such as Freekote 700 or by the application of FEP or TFE Release Film, bonded in place during the cure cycle. Mosites # 14287 possesses excellent retention of physical properties after exposure to the high pressures and elevated temperatures encountered in autoclave cure cycles of composite manufacturing. The product has a service temperature range of – 100°F to + 450°F.
The physical properties shown below were obtained on 0.080-inch thick molded ASTM samples. They are typical of Mosites #14287, but they should not be used to set Quality Control Specification minimum requirements.Download Safety Data Sheet » Download Technical Data Sheet »
