About Mercapto Functional Silicone Fluids

Mercapto functional silicone fluids provide means of incorporating silicone fluids into various curing systems, thereby improving properties such as flexibility or high temperature resistance. The Mercapto-alkyl functionality reacts primarily with systems containing double bonds by the following reaction:

Mercapto Functional Silicone Fluids

Fluids containing Mercapto-Alkyl groups have a high affinity for metal surfaces, much like amine functional silicones. Therefore, they can also be used in release agent applications.
