Application:
CB-680 is the similar product to Si-69 of Degussa and A-6194 of –UCC.
1)Coupling agent in non-carbon black sulfur vulcanization rubber system for those filler such as SiO2, Silicates, bentonite, mica…etc. can do the good job, it can increase the modulus and scratch resistance of the rubber product.
2) As an vulcanization Agent instead of sulfur plus the coupling function.
