Silane coupling agent TS 69 is a kind of multifunctional silane
coupling agent that has been used successfully in the rubber
industry. It is used to improve physical and mechanical properties
of vulcanizates. It is able to markedly improve tensile strength,
tearing strength and abrasive resistance and reduce compression set
of vulcanizates. In addition, it can reduce the viscosity and
improve the processability of rubber products.
Silane coupling agent TS-69 is especially suitable to improve the
reinforcing properties of fillers that contain hydroxyl groups in
all unsaturated polymers having double bonds or their blends.
Silica, talc powder, mica powder and clay can be used in
combination with TS-69 in polymers such as NR, IR, SBR, BR, NBR and
