Properties

Silane OSi HIOSil S752 is an essential coupling agent widely used in the industries below:

• Silane OSi HIOSil S752 reacts with fillers containing silanol groups during mixing and with the polymer during the vulcanization process under the formation of covalent chemical bonds. This imparts better tensile strength, higher modules, reduced compression set, increased abrasion resistance, and optimized dynamic properties. 

• Silane OSi HIOSil S752 is used in many applications where white fillers containing silanol groups are involved and optimum technical properties are required.

Applications

Silane OSi HIOSil S752 is a vital additive in many industries as below:

• Tires: An excellent reinforcing agent in tires to reduce heat build-up, reduce rolling resistance, and improve the tires' wet grip.

• Shoe Soles: Generally applicable silane for improving the 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 surfaces in polysulfide, nitrile, and other rubber adhesives, sealants, and coatings.
