Silquest™ A-178
Silquest™ A-178 silane is a coupling agent for glass fiber and particulate filler reinforced composites. It is a 100% active methacrylamido functional silane that may be used to promote adhesion between a wide range of resins and substrates and reinforcements. It is also useful as a monomer in the synthesis of organic polymers. It functions as a moisture- activated crosslinking agent.

- Recommeded Usage
Silquest A-178 silane is recommended for evaluation in instances where inorganic surfaces such as glass fibers, particulate fillers or metals are combined with organic polymers, for example, unsaturated polyester, vinyl ester, acrylic, polybutylene and polyolefins. This silane is often applied to the inorganic surface from an aqueous solution. The treating solution can be quite simple, consisting of only silane, water and a small amount of acid to adjust the pH. These solutions are used commonly in finishing of heat-cleaned woven glass fabrics or treating particulate fillers. More complex solutions often are used when treating glass fibers used for reinforcing organic resins. These treating solutions may contain (in addition to Silquest A-178 silane) water-soluble organic polymers or emulsions of organic polymers as film formers, lubricants, anti-static agents, wetting agents, water, acids or buffers and other silane coupling agents.
