Product description: JH-S69C Solid Material of Silane Coupling Agent 1. Chemical Name: Bis[3-(triethoxysilyl)-propyl]tetrasulfide(50%) and Carbon Black(50%) 2. Formula: ?????N.A. 3. Properties: Black fine granule with slight alcohol odor. 4. Application: It is a mixture of JH-S69 silane coupling agent and N-330 carbon black with the same function as JH-S69 but easier to operate. It can improve the physical and mechanical properties of rubber and greatly strengthen tensile strength, antitearing strength, and abrasion resistance, reduce the permanent deformation and viscosity of gross rubber, improve process property. The suitable polymers include NR, IP, SBR, BR, NBR, EPDM, etc. 5. Packing and storage: (1) Packing: PE bag, net weight: 25kg/bag or other packing on request.(2) This product must be sealed and kept in cool & ventilated place.
