Application

 

 

 

YAC-S619 is a multi-functional silane coupling agent successfully used in the rubber industry. Its role is to improve the compatibility of rubber with filler, then enhance the reinforcing effect of the filler. YAC-S619 can significantly improve the mechanical properties of the vulcanizates, reduced rolling resistance, compression heat, wear and permanent deformation; This product can eliminate the effect from filler on the curing speed and the degree of crosslinking; can reduce the Mooney viscosity of the rubber material, improve process and reversion elimination.

YAC-S619 is suitable for the double bond-containing polymers (such as NR, NBR, SBR, IR, BR, EPDM, and their mixture) or the rubber formulations by using hydroxyl group-containing fillers (such as silica, silicates, etc.).
