What are silane-terminated hybrid polymers?
A brief explanation
Hybrid silane-terminated polyurethane (STPU) polymers offer a clean, moisture-triggered cure profile that activates only after application.
Free from residual isocyanates, RADIASIL® systems simplify handling and reduce the risk of side reactions. The polyurethane backbone contributes strength and flexibility, while silane chemistry ensures reliable adhesion to diverse substrates — from metals to porous construction materials.
Once cured, surfaces remain paintable, supporting seamless finishing.
