摘要： A polyurethane sealant composition containing terminal-NCO groups, at least 5 percent of the -NCO groups being end-blocked with -Si(OR)3 groups, where R is a lower alkyl. The terminal silane groups provide adhesion retention of the sealant to substrates such as metal or glass even after prolonged water immersion.
