When Is Wax Slurry Added To Water-based Wood Paint

2024-07-09   Pageview:26

Wax slurry is a commonly used additive for coatings and inks. The most commonly used variety in solvent-based systems is micro-powder wax, and its material types are generally polyethylene wax and polytetrafluoroethylene wax. The main function is to resist scratches and abrasion, and also has the characteristics of improving hand feel, anti-adhesion, anti-fouling, and waterproofing. Another important type is solvent-based wax slurry, and its material types are generally amide wax, oxidized polyethylene wax and water-based wax, amide wax and oxidized polyethylene wax. The main function of wax slurry is rheological control such as anti-settling and anti-sagging, and the main function of water-based wax slurry is aluminum powder orientation.

In water-based coating systems, water-based wax as an additive mainly includes solid water-based micro-powder wax and liquid wax emulsion and water-based wax dispersion.

The main advantage of water-based micro-powder wax is that it does not contain emulsifiers and has no effect on the water resistance of coatings and inks after film formation. Its main disadvantage is that it has high technical requirements for dispersion in water-based systems and poor application convenience.

The advantages of wax emulsion and wax dispersion are easy to use, multiple product specifications, and a wide range of choices. The disadvantages are that the matching relationship with the pH value and ionicity of the water-based resin system must be fully considered, and the high temperature and low temperature resistance of the wax emulsion and wax dispersion period and storage and transportation must be considered. With the development of society, the demand for wax in ink coatings is getting higher and higher. Since ordinary wax and wax emulsion contain emulsifiers, the performance of ink will be affected. Tianshi wax slurry can be added to the ink to improve the wear resistance and scratch resistance. After the wax slurry is added to the ink, it floats to the surface of the coating during the film formation process, evenly disperses, and forms a wax protective layer on the coating. It has a good particle size distribution, and the product has good water resistance and chemical resistance, and also has excellent anti-friction performance.
