2250 is an organic silicon surfactant for water-based systems, it can strongly reduce surface tension and has excellent substrate wetting and leveling property. It has low foam and has anti-crater effect. It can improve the wettability of water-based coatings on substrates that are difficult to coat and prevent shrinkage holes. It can also improve the substrate wettability of printing ink and can be used for the wetting of synthetic leather release paper etc.
