Physical standard: Colourless or light yellow transparent liquid. Soluble in methanol, ethanol, ether, acetone, gasoline etc.

Application: The product is mainly used as crosslinking agent of room-temperature vulcanizing silicon rubber and silicon glass adhesive (acid).

The crosslinking agent applies to adhesion between silicon rubber and plastic, nylon, ceramic and aluminum and used as inhibitor and additive of synthetic rubber.

Storage: The product should be stored in cool, ventilated and dry place and away from source of fire and heat and high-temperature area.

Package: Large and small plastic drum; net weight: 230 kg, 25 kg respectively; please note if using other package.


The company can offer products that are adaptive to different seasons.

Methyltriacetoxysilane (modified): HY-218/HY-240/HY-248/HY/212


As an auxiliary agent for producing acid silicon adhesive, the cross-linking agent is produced through acetic anhydride method in traditional method and may lead to high chloride ion content, strong simulation taste and high cost. By developing the new acetic acid method, the company has greatly improved product quality and reduced the cost, and realized zero pollution of environment.
