Application:
3-Methacryloxypropyltrimethoxysilane (CAS No. 2530-85-0), is an important additive for many applications. Examples are:
1.Significantly 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.
2.Enhances the strength performance both initially and after wet-conditioning, of cured polyester resin composites filled with silica, glass fiber, silicates and many metal oxides.
3.Enhances the wet electrical properties of many mineral-filled composites, such as crosslinked polyethylene and polyvinyl chloride.
5. Mainly used in unsaturated polyester composite material to improve the mechanical property, electric property, photic property ,especially, greatly improve the wet property of composite material.
6. Invasive treatment (containing this coupling agent) to glass fibre, can improve the wet mechanical property and electric property of glass fibre reinforced composite material.
7. In wire and cable industry, when used to treat EPDM system stuffed by pottery clay and crosslinked by peroxide, it can improve consumption factor and specific inductance captance.
8. Used in surface treatment for fumed silica, talc, mica, kaolin to improve adhesion, water-risistance and lower curing temperature.
9. Polymerize with vinyl acetate and acrylic acid or methyl acrylic acid monomer.These polymers are widely used in coating, adhesive and sealing agent, providing excellent adhesion and durability.
