CAS NO.: 40372-72-3 Chemical name: Bis(triethoxysilylpropyl)tetrasulfide Formula: (C 2 H 5 O) 3 SiCH 2 CH 2 CH 2 -S 4 -CH 2 CH 2 CH 2 Si(OC 2 H 5 ) 3 Formula Structure: ECOPOWER NEW MATERIAL Equivalent type: SI-69(Degussa,German), Z-6940(Dow Corning,US), KH-8454(China), A-1289(Compton,US), Y-6194(United Carbide,US), KBE-846(Shin-Etsu,Japan) Application: Crosile69:Sulfur-silane is one of the most functional rubber additives, reacts with fillers containing silanol groups during mixing and with the polymer during the vulcanization process under formation of covalent chemical bonds. Crosile69 is a bifunctional, sulfur-containing organosilane for rubber applications in combination with white fillers containing silanol groups.This imparts better tensile strength, higher module, reduced compression set, increased abrasion resistance and optimized dynamic properties. Crosile69 is used in many applications where white fillers containing silanol groups are involved and optimum technical properties are required. In almost all fields of the rubber industry where silanol group-containing white fillers are used and optimum technical properties are required. Crosile69 extensive use in the rubber and tires industry, main application as below: Tires:An excellent reinforcing agent in tires to reduce heat built-up, reduce rolling resistance and improve the tires wet grip. Shoe Soles:Generally applicable silane for improving abrasion resistance of sole compounds containing precipitated silica. Mechanical Rubber Goods:General use silane for achieving good dynamic properties, low compression set and high abrasion resistance in mixtures containing white fillers. Adhesives and sealants :An excellent adhesion promoter to glass, aluminum, steel and other inorganic surface in polysulfide, nitrile and other rubber adhesives, sealants and coatings.

Silane Coupling agent Crosile570 Silane Coupling agent Crosile 570(3-Methacryloxypropyltrimethoxysilane) is a methacryl-functional silane, it is a clear, light and heat sensitive liquid with a faintly sweet odour. Silane Coupling agent Crosile 570(3-Methacryloxypropyltrimethoxysilane) is used as adhesion promoter at organic/inorgainc interfaces, as surface modifier (e.g. imparting water repellency, organophilic surface adjustment) or as crosslinking of polymers). Crosile570 is used as a coupling agent to improve the physical and electrical properties of glass-reinforced and mineral-filled thermosetting resins under exposure to heat and/or moisture. Crosile570 is typically employed as a blend additive in resin systems that cure via a free radical mechanism (e.g. polyester, acrylic) and in filled or reinforced thermoplastic polymers, including polyolefins and polyurethanes. Crosile570 is also used to functionalize resins via radical initiated processes – copolymerization or grafting – and to modify surfaces. Applications Crosile 570(3-Methacryloxypropyltrimethoxysilane) can improve strength as glass fiber size composite in reinforced polyester composites. Enhance initial and wet strength of reinforced polyester resin composites. Enhance the wet electrical properties of many mineral-filled and reinforced composites. Crosslinked acrylic type resins can improve adhesion and durability
