Specifications: Alcohol content £0.5% R2 Content £3.0% Other impurity content £1.0% Viscosity 25°C (cps) £ 14.0 Sulfur Content (%) 15.0 ± 1.0 Specific Gravity (25°C) 1.040 ± 0.020 Refractive Index (25°C) 1.460 ± 0.020 ¶ g2: g-chloropropyltriethoxy silane. · It mainly contains some silane impurities.Application Range: DS-75 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. 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. 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.
