KBM-503

Shin-Etsu Silicones of America makes their documentation available in the regions indicated below:

KBM-503, 3-methacryloxypropyltrimethoxysilane, is a di-functional silane coupling agent having a reactive acrylic group as well as three hydrolyzable methoxy groups. It is a useful modifier for many high performance products including optical fibers, acrylics, epoxies, unsaturated polyester-fiberglass composites, and sol-gel composites. The reactive acrylic group can be copolymerized with many different unsaturated organic monomers such as vinyl monomers, organoacrylic monomers, styrene, or modified styrenes (copolymerization parameters e = 0.07, Q = 2.7). This yields polymers bearing pendant trimethoxysilyl groups, which can serve several different purposes. These groups can render a system cross-linkable upon exposure to water such as atmospheric moisture or steam. The pendant trimethoxysilyl groups can also improve the physical properties of composites by enabling the organic polymer to bond directly with the inorganic filler. Furthermore, these pendant trimethoxysilyl groups can dramatically improve the adhesion of organic polymers to many inorganic and metallic substrates.

Company

Shin-Etsu Silicones produces silicones and silicone products for the Paints and Coating Industry. They provide first rate silicone compounds to develop and increase the reliability and all around performance of a product. One such product type, Silane Coupling Agents, are used as a mediator that helps improve and support bonds between inorganic and organic materials. This allows for surface modification and resin modification to take place. It also aids in the increased adhesion and the enhancement of the mechanical durability of composite materials.
