Introduction

SiSiB® SR8620 is a silicone MQ resin available in white powder or flake form. This resin features a compact, double-layer cage structure composed of highly branched, methyl-terminated oligosiloxanes. It contains a certain amount of reactive silanol groups, which can participate in reactions to form highly crosslinked and stable polysiloxane networks in many applications. This unique molecular structure grants SR8620 excellent mechanical properties, insulation, moisture resistance, and the ability to withstand both high and low temperatures.

SiSiB® SR8620 is produced using a solvent-free process, free from harmful organic solvents such as isopropane and xylene.
