Application
Bis[3-(triethoxysilyl)propyl]tetrasulfide (CAS No. 40372-72-3), silane coupling agent KH-69, reacts with fillers containing silanol groups during mixing and with the polymer during the vulcanization process under formation of covalent chemical bonds. This i***rts better tensile strength, higher module, reduced compression set, increased abrasion resistance and optimized dynamic properties. KH-69 is used in many applications where white fillers containing silanol groups are involved and optimum technical properties are required.
1¡¢Tires: An excellent reinforcing agent in tires to reduce heat built-up, reduce rolling resistance and improve the tires´ wet grip.
2¡¢Shoe Soles: Generally applicable silane for improving abrasion resistance of sole compounds containing precipitated silica.
3¡¢Mechanical Rubber Goods: General use silane for achieving good dynamic properties, low compression set and high abrasion resistance in mixtures containing white fillers.
4¡¢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.
