Silylated Polyurethane Technology Suitable for Construction Applications

摘要

Organofunctional silane capped polyurethane (SPUR~(SM)) prepolymers have been employed in adhesive and sealant formulations for many years. SPUR technology provides not only NCO free prepolymers with good durability and excellent adhesion performance but also polymers to be tailor-made to have high or low modulus for different applications. This presentation will describe how to make a low modulus sealant which utilizes the SPUR prepolymers for construction applications.
