Wetting agents

  • Product listing


In some applications such as deep hole drilling or high speed grinding metal working fluid emulsions hardly get to the contact point between tool and workpiece. This leads to an insufficient lubrication and therefore to an excessive wear and higher processing costs. Our wetting agents, or wetting surfactants, help to avoid this phenomena and increase lubrication at the contact point. Our wetting agents show excellent performance in oil-based and water-based metal working fluids and are applicable in metal cleaner formulations, too.

The Lubricant Additives segment of Evonik Industries offers wetting agents based on both organomodified siloxane and purely organic chemistry. Particularly, organomodified siloxane-based wetting agents can extremely reduce surface tension of metal working fluid emulsions.

Our alcohol alkoxylates are slightly less effective compared to siloxane-based wetting agents, but they better withstand extreme conditions like high or low pH values. In addition they show a lower foaming tendency compared to simple sulfosuccinates.
