Degussa’s Tego Twin 4000, multi-functional surfactant combines defoaming and substrate wetting properties for water-based wood coatings. Tego Twin 4000 is a 100% active matter multi-functional surfactant based on an organo-modified polysiloxane. The surface tension reduction imparted by the surfactant gives outstanding wetting and anti-cratering properties, according to the company. Its high surface activity means that very low addition levels are required. The overall result is a reduction in the total additive content of the formula, providing significant savings as well as making formulation simpler.
