Evonik Goldschmidt Corp. has introduced Tego Twin 4100, a multi-functional, high surface activity surfactant that delivers long-term foam stabilization, compatibility with sensitive resins, and improves flow and leveling. The reduction in surface tension enables substrate wetting on difficult-to-wet substrates, with the added benefit of an anti-crater effect. Effective defoaming characteristics have been demonstrated in a variety of waterborne formulations for plastics, wood and metal.
