The new technology platform unites the advantages of silane curing with those of polyurethanes, all within one and the same chemical network. This leads to very hard, durable coatings, while still providing adequate flexibility. Two isocyanato alkoxysilanes - IPMS (3-isocyanatopropyl)trimethoxysilane and IPES (3-isocyanatopropyl)-triethoxysilane - are at the heart of this new technology. The NCO group binds these compounds to a backbone component, where they combine with the alkoxysilane groups to form moisture-curing adducts (Figure 1). These adducts are suitable for both one- and two-part (1K and 2K) coating formulations - and the concept even allows for their use ...
