Features and advantages:
HW404D has excellent defoaming and anti-foaming effects, which can inhibit and eliminate the bubbles generated during the production, canning and construction of coatings, especially for the bubbles generated by the reaction of two-component coatings and high zinc stearate The defoaming effect in the formula is remarkable. Since HW404D has an incomparable defoaming effect with other types of defoamer, it is very effective in primers.
