What’s the Effect of Aqueous Painting Defoamer in Water-Based Paint?

With the development of technology, water-based paints are more and more popular in different industries.This is because water-based pains can reduce pollution without pungent smell and keep environment friendly.However, it may cause foam under various factors during the production process.If we don’t deal with these foams immediately, it will have a strong impact on the quality, appearance, cost and production efficiency of the products.But don’t worry, Zilibon can get rid of this problem easily by the aqueous painting defoamer.

Several reasons of foam causing in the water-based paint:

1.Foam causing in the process of mixing with other surfactant,expanding the volume of paint,reducing the utilization rate of blending equipment.

2.The foam astrict the speed of mixing,prolong the time of blending and avoid the full wet between the filler and dye.

3.Due to the foam existing ,the packing barrels cannot be filled; the packing barrels also hard to keep in a standard weight after the foam disappearing;finally interference with continuous packaging.

4.The foam appear to be long lasting, result in poor liquidity in the process of construction,cause a rough or damaged surface and broke film build after using the paint.

5.During the process of coating(such as spraying,rolling,silk printing),appear the bubble and impact the quality of product.

Working principles of aqueous painting defoamer：

1.Marangoni effect: surfactant lead liquid to happen reflux phenomenon, which can counteract gravity.

2.Electrostatic effect:The electrostatic repulsion of the surfactant thickens the liquid layer film of the foam,thereby stabilizing foams.

Beside the outstanding aqueous painting defoamer, Zilibon has developed over 30 industrial anti-foaming agents and provided professional solutions for more than 8,000 manufactures worldwide.

Zilibon is a manufacturer with 16 years of application experience. It has far more defoaming technology than other antifoaming agents in the market. From the above cases, we prove the strength of our Zilibon defoamer. We have a group of excellent defoaming engineers, and An independent laboratory that facilitates defoaming experiments with foams that are difficult for customers to solve.
