Chemical Structure

Introduction

DP-680 is a clear and almost colorless fluid with a typical smell (MEKO). It readily hydrolyzes upon contact with moisture.

Application:

DP-680 is used as a neutral curing agent in silicone sealant formulations. Compared to formulations based on methyloxime silanes only, the use of combinations containing methyl- and vinyloxime silanes leads to a shorter skin formation time of the silicone sealant without a reduction of the curing time. The ability of the sealant to withstand stress early, required for a certain elasticity and tear resistance, is achieved.
