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.
