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 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 and thermal resistance and good elastic recovery properties. The polymers release ethanol during the curing process.
