DS-75

Technical DataSheet | Supplied by Ecopower Chemical

DS-75 is bis [3-(triethoxysilyl) propyl] disulfide. Acts as a coupling agent. It improves 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. DS-75 is especially suitable to improve the reinforcing properties of fillers that contain hydroxyl groups in all unsaturated polymers having double bonds or their blends. Fillers like silica, talc powder, mica powder and clay can be used in combination with this coupling agent in polymers such as NR, IR, SBR, BR, NBR and EPDM. Recommended dosage is 1.0-4.0 PHR. It has a shelf life of 1 year.
