Silane-modified polymers have been used to formulate sealants and adhesives since the late 1980s. The major advantage of this class of polymers is that they combine the outstanding properties of silicones with those of polyurethanes. The products are successfully used for many different applications fields.

Evonik’s silane-modified product range is based on two different polymer technologies:

The Polymer ST portfolio covers a very broad range of mechanical properties: Polymers allow the formulator to produce from a very soft sealant up to a very tough adhesive. Solutions for parquet adhesives are also available.

The new TEGOPAC^® family differs from standard silane-modified polymers: polymers are based on a unique polymer technology with lateral crosslinking groups. Sealant and adhesive formulations with TEGOPAC^® polymers show excellent through cure properties, improved water & thermal resistance and good elastic recovery properties. The polymers release ethanol during the curing process.
