5. Use of 3-Thiocyanatopropyltriethoxysilane
3-Thiocyanatopropyltriethoxysilane is used in the rubber industry in combination with white fillers that carry silanol groups. In additon, it is used in many applications where white fillers are applied and optimum technical properties are required. It is more effective in lowering compression set and improving abrasion resistance. Last but not least, it has function the same as JH-N303 in some areas, such as shoe soles and mechanical rubber goods.
