SiSiB® PC2200


The novel silane coupling agent SiSiB® PC2200 solves the above problems of the conventional art. The polysulfide structure in which the distribution of sulfur is specified can ensure its stability at high temperature. Thus, it can be avoided to decarbolize to form free sulfur. 

The silanol group on the surface of silica can react sufficiently with the silane coupling agent. And at the same time, the dispersion of the silica into a rubber is remarkably improved; furthermore there are no effects on the property processing. Thus it can improve the productivity of rubber processing and the low heat buildup property and abrasion resistance is improved.

SiSiB® PC2200 bis 3 triethoxysilylpropyl disulfide is the equivalent of Momentive's A-1589, Dow's Z-6920, Evonik's Si-75 silane.
