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. For sealants and adhesives that demand safety, durability, and versatility, RADIASIL is a smart choice.
