Ambient temperature curable isocyanate-free compositions for preparing crosslinked polyurethanes |
摘要 |
The present invention provides a multicomponent composition that is substantially isocyanate-free and comprises a polycarbamate as a first component and a polyaldehyde or an acetal or hemiacetal thereof as a second component and further comprises an effective amount of a triggering agent such that the first and second components to cure at a temperature of from 0C to less than 80C to form a crosslinked polyurethane. The multicomponent composition forms an ambient temperature curable composition when all of its components are combined that has a pH of 7.0 or less. The present invention also provides processes crosslinked polyurethanes, and the crosslinked polyurethanes prepared by the processes. |
