Product features and uses:

1. This product is especially suitable for sulfur vulcanization and metal oxide vulcanization system rubber, which can obviously improve the performance of inorganic filler to reinforce rubber, such as tensile strength, tear strength, heat resistance, wear resistance, resilience and compressibility Etc., and can improve the rheology, especially in light-colored rubber products.
2. This product can replace the general-purpose polysulfide silane. In the formula of low rolling resistance tires and rubber rollers, only a lower amount can achieve the same performance.
3. This product can be used as an adhesion promoter in the formulation of paints and adhesives, and can also be used to modify polyurethane adhesives.

Packing: 20KG/barrel.
