One-Component Urethane Sealants Synthesis

Abstract:

It is proposed to synthesize one-component light-resistant urethane compositions using aldimines as crosslinking agents and methyl iodide as an activating agent to obtain sealants. The effect of the methyl iodide activator and the quaternized complex of the imine group and temperature on the cure time of the sealants was investigated. The influence of the polyether molecular weight and the structure of aldimines fillers on the physical and mechanical properties of the obtained sealants was studied.
