Silane XG-669 is a kind of silane coupling agent with
multiple functional groups in below industries:
 Low rolling resistance tires, mechanical rubber
goods and soles
 Used in rubber industry to improve modulus
and tensile strength of rubber, to reduce the
compound viscosity and save process energy
consumption
 It’s especially applicable for polymers with
double bond or rubber formulation with hydroxyl
fillers.
 XG-669 is also available as a dry blend (1:1)
with carbon black, named XG-669C.
