Polymer ST 97 is a silane-terminated polymer with low viscosity for the manufacturing of hard-elastic adhesives and liquid applied membranes.
Polymer ST 97 has a particularly low viscosity for quick dosing during the production process. It also has a high filler loading capacity allowing for economic formulations with good flowability and mechanical performance. Self-levelling and even sprayable formulations are possible.
It is compatible with all common aminosilane based adhesion promoters (Dynasylan®) and thus shows excellent adhesion on a great variety of substrates.
Polymer ST 97 can be used for plasticiser-free formulations, but it can also be combined with non-reactive plasticisers like Elatur® CH and Plasticizer 860 IP or with reactive diluents like Tegopac® RD.
