Silicone Resins
WACKER produces and markets silicone resins under the brand name SILRES®. Silicone resins are classified as organopolysiloxanes and consist of an irregular three-dimensional network composed of mainly tri- or tetra-functional units.
These organopolysiloxanes are very stable due to the strength of the Si-O bond. Silicone resins can be combined with many organic polymers, and this makes it possible to tailor a large number of properties to the intended application, e.g. curing behavior, flexibility, adhesion, and resistance to weathering.
SILRES® silicone resins are available in different product forms:
- Silicone resin emulsions
- Silicone resin solutions
- Silicone resin copolymers
