utility

The effective ingredient SI-69 of wear-resistant agent SI69-50GE is a liquid sulfur-containing silane coupling agent.

Molecules have dual functional groups that can hydrolyze alkyl and organic sulfur groups. During mixing, alkyl groups condense with silanol groups on the surface of white carbon black to form siloxane bonds; Organic sulfur groups form covalent bonds with rubber during vulcanization.

The effect of adding this series of silane coupling agents is manifested in the significant improvement of the physical and mechanical properties of rubber products, such as tensile strength, wear resistance, permanent deformation, tear resistance, etc.

At the same time, adding silane coupling agent during the rubber mixing process significantly reduces the Mooney viscosity of the rubber material and improves its sulfur conversion performance, making it an ideal processing aid.

usage

Suggested dosage: 2-6 phr

Storage suggestions

1. Please keep the packaging sealed and store it in a cool, dry, and well ventilated place, avoiding direct sunlight.

2.SI69-50GE will lose its effectiveness when it interacts with water. To ensure its activity, it should be avoided from coming into contact with water vapor before interacting with white smoke (silicate, clay).

Packaging: 25KG/box
