- Behavior and Effects
Due to its bifunctionality Deolink TESPT-25 links through the ethoxy group to the Silanol groups of active white fillers and provides through its tetrasulfane group links to elastomers. The chemical bond between polymer and filler improves the physical properties of the vulcanisate.
