Silicones

Silicone Conformal Coatings

Silicone conformal coatings are most widely used in high temperature environments due to their innate ability to withstand prolonged exposure to higher temperatures than most other conformal coating chemistries. This attribute has made them the primary choice for under hood automotive applications. They are also capable of being applied in thicker films making them useful as a vibration dampening/isolation tool if the coated assembly is to be placed in a high vibration environment. Rework of Silicone coated assemblies can sometimes be difficult due to their chemical resistance and the fact that, unlike Acrylics and Polyurethanes, they do not vaporize with the application of heat. These products do not necessarily represent our complete Silicones range.
