Si 75®

Bis[3-(triethoxysilyl)propyl]disulfane

Typical Applications

Low rolling resistance tire treads

Benefits at a glance

Si 75® reacts with hydroxyl groups of white fillers during mixing and with the polymer during vulcanization under formation of covalent chemical bonds. Compared to the polysulfidic organosilane Si 69®, Si 75® has a higher temperature stability and therefore allows higher mixing temperatures. Si 75® imparts greater tensile strength, higher moduli, reduced compression set, increased abrasion resistance, and optimized dynamic properties.

Further Information

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
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.
