GENIOSIL® STP-E

Wacker Chemie AG Brand

Products:3

GENIOSIL^® STP-E are silane-crosslinking organic polymers that combine properties typical of both silicones and polyurethanes. They are highly versatile yet easy and safe to use as they are isocyanate and solvent-free and in case of the α-polymers do not require tin-catalysts for curing.

GENIOSIL® STP-E 10

Features:Low Glass Transition Temperature, Water Resistance, Multi-Substrate Adhesion, Fast Cure, Improved Ageing Resistance

GENIOSIL® STP-E 10 is a polyether-based silane-terminated polymer suitable as a binder in moisture-curing formulations. It differs from conventional silylated polymers due to its high reactivity, which results from the structural proximity of the nitrogen atom to the silicon atom in the dimethoxy(methyl)silyl-methylcarbamate group (alpha-effect). It hydrolyzes in the presence of moisture to form a stable siloxane network initiated by mild catalysis, rather than heavy metal ions.

GENIOSIL® STP-E 30

Chemical Family:Silane-Terminated Polyether (STPE)
Features:Low Glass Transition Temperature, Water Resistance, Multi-Substrate Adhesion, Fast Cure, Improved Ageing Resistance, High Reactivity

GENIOSIL® STP-E 30 is a polyether-based silane-terminated polymer specifically designed as a binder in moisture curing formulations. It finds application in various industries including building and construction, industrial adhesives, and do-it-yourself projects. This versatile polymer is particularly suitable for building and construction adhesives, do-it-yourself projects, and flooring installations. It also serves as an effective binder in industrial adhesive formulations.

GENIOSIL® STP-E 35

Chemical Family:Silane-Terminated Polyether (STPE)
Features:Multi-Substrate Adhesion, Fast Cure, Improved Ageing Resistance, High Reactivity, Low Glass Transition Temperature, Water Resistance

GENIOSIL® STP-E 35 is a polyether-based silane-terminated polymer suitable for use as a binder in moisture-curing formulations. Unlike conventional silylated polymers, it exhibits high reactivity, thanks to the trimethoxysilyl group attached to the organic backbone. In the presence of moisture, it undergoes hydrolysis and ultimately forms a stable siloxane network, which is initiated by heavy metal or strong amine catalysis.
