Water-based paints are widely used, and they are widely used in home building materials and decoration. According to the different coating locations, it is divided into interior wall coatings, exterior wall coatings and interior coatings for the automobile manufacturing industry, as well as textile coatings, leather coatings and other applications. Under the action of high-speed stirring of water-based paint and paint additives, the paint is prone to produce a large number of bubbles. Usually we add water-based paint defoamers to control the generation of foam.

Water-based paint is a coating with water-based polymer as the film-forming substance, which replaces the traditional organic solvent as a solvent, and reduces the paint’s harm to the environment and human health. The water-based paint is easy to use and has good film-forming properties. It reduces painting time and energy consumption. Since the emergence of water-based coatings in the 1960s, especially after the 1990s, the development speed has been very fast, and a huge system with multiple varieties, multiple functions, multiple uses and multiple specifications has been formed.

In the process of configuring water-based paint, in order to improve the performance of the coating, coating additives will be added to give the coating good film performance. There are about 40 different types of coating additives, including emulsifiers, dispersants, defoamers, thickeners, anti-crater agents, drying accelerators, bactericides, etc. Among them, the defoaming agent mainly plays an important role in foaming, defoaming and foam suppression.
In the process of water-based paint configuration, foam will inevitably occur, which will hinder production, affect the quality of the coating product, and affect the coating of the coating. The foam in the coating is likely to cause defects such as shrinkage and fish eyes during coating construction, which greatly affects the use Effectively, adding defoamer to the coating formulation is a good defoaming method.

The Nanhui defoamer manufacturer has developed a new type of polyether paint defoamer that has a good defoaming and anti-foaming effect in response to the process characteristics of water-based paint production that is easy to foam. The paint has good film-forming effect, rich defoaming experience in the industry, and many customer cases.
The paint defoamer developed and designed by Nanhui for water-based paint has the following advantages:
·Direct supply from the manufacturer, preferential price and good performance;
·Nanhui provides free defoamer samples and one-to-one technical support;
·The addition amount is small, the defoaming is fast, and the performance of the defoaming agent is stable;
·Good water solubility, can be well dissolved with the foaming system, quickly diffuse and defoam;
·The foam suppression time is long. Adding only the foam in the water-based paint that can suppress foam for a long time, the can opening effect is good;
·The formula concentration is high and the dosage is small, which will not affect the product quality of the water-based coating system.
The source manufacturer of Nanhui defoamer can solve various industrial foam problems in a targeted manner. If you encounter foam problems in related industries, you can call Nanhui technical specialist Ms. Yoyo at 0086 134 2860 1010.
