Introduction
Methacryloxypropyltrimethoxysilane. H2C=CH(CH3)C(O)OC3H6-Si(OCH3)3 Coupling agent for unsaturated resin systems.
Its utility in the manufacturing of many intermediate product such as: unsaturated polyester, ethylene-propylene copolymer, polystyrene, ABS, polyurethane,polybutadiene and polyethylene crosslinked by peroxide. Modified by silane coupling agent can not only be used as filling of artificial marble to reinforce the bending strength of board but also greatly reduce the production cost of artificial marble.SERVICE AT USICHEMICAL DOT COM

Application
Glass Fiber Soakage Agent
Glass fiber soakage agent is used in the treatment of glass fiber. It contains filmerformer, lubricant, anlistatig,silane coupling agent and water etc. The concentration of the silane coupling agent should be of 0.3%-0.6%.
Electrical wire and cable
When used in electrical wire and cable, USi-3301 can greatly improve its mechanical property and electrical property .When applied in argil, USi-3301 has dramatically better the consumption factor, inductance and capacitive reactance of the EPM (ethylene propylene monomer) and EPDM (Ethylene-Propylene-Diene Monomer) systems crossed linked by peroxide and filled with argil. USi-3301 results 2.5 times better than vinyl silane with the same dosage.
Filler Treatment
This silane can improve the mechanical strength of polyester composite materials made from filling white carbon black,glass, silicate and metal oxide in either dry or wet state, for instance, crosslinked polyethylene and polyvinyl chloride.
Adhesive and Coating
USi-3301 can be applied in acrylic resin and polyester adhesive improving its water resistance and adhesion stress with inorganic material, and also lowering its solidification value.
