Vinyltriethoxysilane, also referred to as A-151, NV-1107, KBE-1003, or GF-56, is a colorless liquid with the chemical formula C8H18O3Si. It can dissolve in organic solvents and is extensively utilized as a coupling agent and adhesion promoter in diverse industries such as plastics, rubber, and coatings manufacturing.
| Application |
| The couping agent is used in polymer systems that undergo curing through a free radical mechanism. It serves as a finish for glass or a binder additive in glass-reinforced polyester resins. Additionally, it acts as an integral additive in mineral-filled polyester or DAP resin compounds. It is also utilized as an additive in mineral-filled elastomers that undergo peroxide vulcanization. |
