Polymer ST and TEGOPAC® - Your solutions to innovative sealants and adhesives

With Polymer ST and TEGOPAC® we are offering two different silane-modified polymers mainly used in the adhesives and sealant industry.

The well-established Polymer ST is a SPUR (silane-terminated polyurethane) to be used in a multitude of different formulations ranging from low modulus sealants to high modulus flexible adhesives TEGOPAC® is a new-SP (new silane-modified polymer) that differs from Polymer ST having lateral silane modification and high variability in the polymer backbone. Thus, resulting in benefits such as higher elasticity, excellent recovery, better through-cure, higher stability and advanced adhesion properties.  

POLYMER ST is a range of linear polyether based polymers with trimethoxy silane terminations. Their polymer architecture as well as their plasticizer content have been optimized to fit various applications. They open the way to a wide range of product properties.
