Silane Coupling Agent 570
Abstract
3-Methacryloxypropyltrimethoxysilane (CAS No. 2530-85-0), Silane coupling agent -570, is a versatile methacryloxy functional silane coupling agents used to improve the physical and electrical properties of glass reinforced and mineral filled thermoset resin, typically those curing via a free-radical mechanism (e. G. Polyester, polyurethanes and acrylics) and in filled or reinforced thermoplastic polymers, including polyolefins and thermoplastic polyurethanes.

Application
3-Methacryloxypropyltrimethoxysilane (CAS No. 2530-85-0), Silane coupling agent KH-570, is an important additive for many applications. Examples are:
1Significantly improves composite strengths when the composite is reinforced with fiber glass roving sized with a typical polyester compatible formulation. These formulations normally incorporate silane coupling agents, film-forming resins, lubricants and antistatic agents.
2Enhances the strength performance both initially and after wet-conditioning, of cured polyester resin composites filled with silica, glass fiber, silicates and many metal oxides.
3Enhances the wet electrical properties of many mineral-filled composites, such as crosslinked polyethylene and polyvinyl chloride.
