Description
LC-PH212 is a methyl phenyl siloxane oligomer with hydrogen at both ends.The molecule contains active Si-H bonds, which can be used as a crosslinking agent for addition molding sealing adhesive. Due to the presence of phenyl functional groups, it has improved high and low temperature resistance, radiation resistance, strong aging resistance, excellent UV resistance, and excellent properties without yellowing after long-term use.
