Silane Modified Polymers

Tegopac® & Polymer ST

Product description

With Tegopac® and Polymer ST our supplier EVONIK offers different technologies for silane modified polymers (SMP). SMP's are basic materials in adhesives and sealants for applications such as construction, industrial assembly and transport.

Tegopac® products are ethanol releasing binders. The backbone is built by different polymers based on renewable raw materials. Systems with high tack and high adhesion are achievable. Through the design of the lateral arranged crosslinking groups, sealants with outstanding elasticity recovery can be developed.

The Polymer ST types are silyl terminated polyether polyurethanes. They release methanol and enable developers to achieve fast curing systems with excellent elongation properties and high strength.
