1. DS-75 is a kind of multi-functional silane coupling agent that has been used successfully in the rubber industry. It is used to improve physical and mechanical properties of vulcanization. It is able to markedly improve tensile strength, tearing strength and abrasive resistance and reduce compression set of vulcanization. In addition, it can reduce the viscosity and improve the process-ability of rubber products.

2. DS-75 is especially suitable to improve the reinforcing properties of fillers that contain hydroxyl groups in all unsaturated polymers having double bonds or theirblends. Silica, talc powder, mica powder and clay can be used in combination with DS-75 in polymers such as NR, IR, SBR, BR, NBR and EPDM.
