Generally, paint defoamer is added at the stage of grinding and filling, and the total amount is 0.1%-0.5%.










In the production of aviation coatings, marine coatings, automotive coatings, architectural coatings and other coatings, bubbles will be generated, because the addition of wetting agents, dispersants and other additives make the surfactants blistering. In the process of film formation, if the bubbles cannot be eliminated in time, it will produce pinhole, shrinkage and other disadvantages. In addition, the finished coating will also produce a lot of bubbles when canned, at this time, you need to add defoamer to ensure the quality of the product.

In the selection of defoamer should also consider the impact of various factors, due to the different varieties of coatings, the main film-forming substances, additives are different, the choice of defoamer is different, defoaming effect is also different, need to be carefully analyzed.

Coating defoamer as can improve production capacity, optimize efficiency, precise control of product quality, cost control advantages of the product has been widely used.
