Surfadol 541BC Defoaming Wetting Agent
Surfadol 541BC is a liquid preparation of 2,4,7,9-Tetramethyl-5-decyne-4,7-diol in 50% 2-Butoxyethanol. It can improve the substrate wetting performance and avoid suface defects of water-based coatings by reducing dynamic surface tension and breaking the foam.
