Due to its characteristic of using water as a solvent, water-based paint is prone to generate bubbles during use. In the formulation of water-based paint, the mixture of various additives, pigments and resins may introduce air, and air will form bubbles during stirring, brushing or spraying. However, the emergence of water-based paint defoamers can effectively solve the foam problem.
Performance characteristics of water-based paint defoamers:
1. Effective defoaming: It can quickly penetrate the membrane wall of the bubble, reduce the tension of the bubble membrane, make the bubble membrane fragile, and thus promote the bubble to burst.
2. Persistent foam suppression: The application of water-based paint defoamers can effectively control the secondary formation of foam. It can form a thin film on the surface of the foam to permanently control the regeneration of new foam.
Application areas of water-based paint defoamers:
1. Architectural decoration: Water-based paint is widely used in the coating of indoor and outdoor walls, furniture, etc. Through its use, it can effectively solve the foam generated in the coating and ensure the smooth gloss of the paint surface.
2. Automobile painting: The use of water-based paint defoamer can ensure that the paint will not produce bubbles during the spraying process, making the paint coating on the surface of the car bright and smooth.
3. Industrial equipment painting: For the painting of industrial equipment, such as machine tools, mechanical parts, etc., water-based paint defoamer helps to achieve high-quality painting and prevent bubbles from affecting the beauty and protective effect of the equipment.
Water-based paint defoamer plays an indispensable role in the use of water-based paint. It can effectively solve the foaming problem of water-based paint and improve the quality of painting. It has a wide range of applications in many fields and can ensure the ideal painting effect.
