Si 69® reacts with hydroxyl groups of white fillers during mixing and with the polymer during vulcanization under formation of covalent chemical bonds. This imparts greater tensile strength, higher moduli, reduced compression set, increased abrasion resistance, and optimized dynamic properties.
Typical Applications
Low rolling resistance tires, mechanical rubber goods and shoe soles
Benefits at a glance
Si 69® is used in all fields of the rubber industry where hydroxy group-containing white fillers are used and optimum technical properties are required.
The product is also available as a dry blend (1:1) with carbon black, named X 50-S® as well as pre-reacted surface-modified precipitated silica, called COUPSIL® 6109 (powder form) and COUPSIL® 8113 (powder and granule form).

Storage:
The storage stability only applies to material stored under appropriate conditions:
- original un-opened packaging
- stored dry and frost-free
- protected from direct sunlight
We recommend using a thermo truck for temparatures <5°C.
Aqueous acids and bases accelerate the transformation of organosilanes to polymeric siloxanes. Therefore, organosilanes should be stored in a dry place, away from acids and bases.
The quality of this product can also be influenced by moisture (humidity). During handling and storage, please prevent humidity from entering the container. Keep container tightly closed during storage and close it immediately after use.
