Deolink MX is a 50% preparation of Thiocarboxylsilane on a polymer carrier system. The bifunctional sulfur silane is compatible with all elastomers that are suitable for sulfur vulcanization. Deolink MX can be used over a broad temperature range and is – at low dumping temperatures – often more active than conventional TESPT. Deolink MX contains a hindered mercapto group and can be used as an alternative to conventional mercaptosilanes. The protective group is removed during processing, thus releasing the mercaptosilane. Using Deolink MX improves the processing by creating higher scorch safety and preventing the typical mercapto odor. The improved processing leads to higher injection volumes and safer processing.

Application

Deolink MX is best dosed into the internal mixer together with the filler at elevated temperatures of about 120 - 160 °C to improve the physical properties of compounds with white fillers crosslinked by sulfur. The incorporation in a PE-wax enables an optimal protection of the active silane against humidity.

Technical Details & Test Data

Behavior and Effects

Deolink MX is an alternative to mercaptosilanes which often cannot be used because of their unpleasant smell. The mercaptosilane present in Deolink MX is set free from the carrier during the mixing process. Because of its bifunctionallity it forms a chemical bond between the rubber molecule and the silica filler at cure temperature.
