Silicone Additives for Coatings & Paints
Silicone Additives for Coatings & Paints
Polysiloxanes (silicones) have a very high surface activity and therefore are often used as surface control additives. Commercial silicone based surface control additives are modified by polyethers, polyesters or alkyl side groups to improve recoatability and intercoat adhesion. Modification parameters are silicone content, molecular weight and modification degree.
ADDSIL™ Reactive silicones
- Hydroxy Functional silicone
- Epoxide Functional silicone
- Acrylate Functional silicone
Reactive silicones can be incorporated into polymers, and provide increased flexibility, stain resistance and improve surface wetting.
ADDSIL™ Substrate wetting agent
Short chain polyether siloxanes are used primarily to reduce surface tension in waterborne coatings. Longer chain polyether siloxanes are better in in solventborne and UVcoatings.
ADDSIL™ Defoamer
Silicone Based Defoamers
ADDSIL™ Anti-graffiti and easy-clean additives
Polysiloxane provides anti dirt pick up and easy cleaning effect. OH-groups allow cross-linking into many reactive binder systems (permanent)
