CFS-096 Cas 14814-09-6 [KH-580] is a mercaptosilane, which has a sulfhydryl functional group and three hydrolyzable -ethoxy functional groups in its molecular structure, and the sulfhydryl group as a sulfur-containing functional group can participate in the vulcanization process of sulfur vulcanized rubber, and there is an active hydrogen on the sulfhydryl group. Therefore, it can also be used for capping modification of isocyanates. This dual reactivity allows it to improve the bonding, adhesion and compatibility between inorganic materials (glass, metals, fillers) and organic polymers (thermosetting resins, plastics, elastomers) through a bidirectional chemical reaction, thus improving the mechanical properties of resin-based composites or enhancing the adhesive strength and water resistance of resin coatings. In different applications, it can be used as coupling agent, adhesion promoter, cross-linking agent, surface modifier of color filler, and capping monomer of polyurethane, etc.

Applications

CFS-096 Cas 14814-09-6 is especially suitable for all kinds of rubber of sulfur yellow vulcanization and metal oxide vulcanization system, which can obviously improve the mechanical strength of inorganic fillers (white carbon black, kaolin, aluminum hydroxide, magnesium hydroxide, talc, etc.) to enhance the mechanical strength of rubber (especially 300% of fixed tensile stress and tear strength), significantly reduce fatigue heat generation, permanent deformation and wear, and improve its processing rheology, especially in the light-colored rubber products. This product can be used to pretreat the mineral filler, and can also be added together with the rubber compounding.

This product can replace polysulfosilane in the formulations of low rolling resistance green energy-saving tires, rubber shoe outsoles, rubber rollers, light-colored rubber conveyor belts and rubber cables, etc. The same performance can be achieved with only a small amount. When making this substitution, the amount of accelerator in the formulation should be reduced appropriately and the amount of sulfur feeder should be increased.

CFS-096 Cas 14814-09-6 can be used as a bonding accelerator in polyurethane and polysulfide adhesive sealant formulations, and can also be used to modify the end of isocyanate, giving polyurethane sealants with moisture vapor curing properties and excellent adhesion and weather resistance.
