PRODUCT PROPERTIES:
It is methylpropenylacyloxy silane, Boiling Point:255°C,Flash point:88°C.
FEATURES AND BENEFITS:
The methacryloxylsilane produced by silane RJ-570.
1.Significantly improves composite strengths when the composite is reinforced with fibreglass 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, silicates and many metal oxides.
3.Enhances the wet electrical properties of many mineral-filled composites, such as crosslinked polyethylene and polyvinyl chloride.
4.May be copolymerized with vinyl acetate and acrylate or methacrylate monomers to prepare silylated polymers that are moisture-curable. These silylated polymer may be used in coatings, adhesives and sealants to provide superior adhesion and durability.
