Silicone resins

The molecules of silicone resins have a three-dimensional network structure. Silicone resins are most often used as resins. They produce films with excellent heat resistance, weatherability, dielectric properties and water repellency. In addition, they are available in a range of consistencies, from high-viscosity liquids to solids. Silicone resins are used to make paints and coatings and in electrical and many other applications, where they help to improve durability, safety and reliability.

Properties when used as resins

Heat resistance

Able to withstand temperatures up to 250°C.


Good resistance to UV rays.


They form hard films due to their three-dimensional network structure.

Water repellency

They form films with excellent water repellency (especially those that contain methyl groups).

Dielectric properties

They show excellent dielectric properties across a wide range of temperatures.
