Textile Auxiliaries

Wetting and Spreading Agents

Our TEGOPREN® polyether siloxanes provide outstanding wetting and spreading performance in textile auxiliary formulations.

The general molecular architecture of these amphiphilic  organo-modified siloxanes (OMS) is based on a polydimethylsiloxane (PDMS) backbone which the copolyethers of ethylene oxide (EO) and propylene oxide (PO) then attach to. These different molecules all vary in chain length and EO / PO ratios.  

Whereas the siloxane backbone provides a low surface tension, the organic moieties help to improve the compatibility of the OMS with the surrounding matrix. In aqueous systems EO-rich polyethers products are preferred, but the best choice for use in oil systems are products carrying PO-rich polyethers.
