Polymeric organosilicon filler activator for rubber compounds. Through the use of Kagevest, a substantial enhancement of the reinforcing action of light-coloured filler materials can be achieved. Kagevest is active with both sulphur and peroxides in the cross-linking of compounds containing silicic acid and silicate fillers.
Mechanism of action: Polymeric organosilicon containing reactive trimethoxysilyl groups which react with the surface of light-coloured reinforcing filler materials, while the unsaturated polymer chain is incorporated in the cross-linked structure of the vulcanized rubber.
