Hydroxycarbamoylalkoxysilane-based poly(ether-urethane) sealants having improved paint adhesion and laminates prepared therefrom

摘要

The present invention pertains to moisture curable sealant compositions based on alkoxysilane functional poly(ether-urethane)s prepared from hydroxycarbamoylalkoxysilanes which provide improved paint adhesion even in the absence of polar solvents or polar plasticizers. The present invention also provides coated substrates and laminates formed from such compositions.
