RIM elastomers based on isocyanurates of isophorone diisocyanate and prepolymers thereof

摘要

This invention relates to RIM molded elastomers prepared from aliphatic isocyanurates and prepolymers thereof. The reactive systems used to prepare these elastomers exhibit longer gel times with improved flow and can still be demolded in about 30 seconds. The resultant elastomers have good weatherability without painting. This invention also relates to phase stable polyol blends.
