| DESCRIPTION |
Si 69® is a bifunctional, sulfur-containing organosilane used in the rubber industry in combination with white fillers that carry silanol groups. - Si 69® reacts with fillers containing silanol groups during mixing and with the polymer during the vulcanization process under formation of covalent chemical bonds. This imparts better tensile strength, higher moduli, reduced compression set, increased abrasion resistance and optimized dynamic properties. Si 69® is used in many applications where white fillers containing silanol groups are involved and optimum technical properties are required
