Zinc Stearate is a common “zinc soap” used widely in modern industries. It is also used as a metal “salt”, a form of a saturated fatty acid. It is a white, water-repellent solid. It repels water, and it’s not soluble or dissolves easily in any polar solvents. It does not contain an electrolyte, but has a hydrophobic property. Its principal applications areas include the plastics, rubber, and automotive industries.
Zinc-stearate emulsion can be found in wood coatings, which are used to coat and enhance the performance of sanding. This paint offers excellent transparency, which can impact the color’s Transparency. Beyond the Transparency and emphasis on grinding, zinc stearate paint emulsion is also affected by oil absorption, Thickening of particle size and dispersibility. These factors can have an impact on the overall performance wood lacquer.
Zinc stearate paint emulsions provide technical information in the wood primer to affect its performance.
1, Grinding
A key indicator is the Inwood primer’s sanding capability. Use the same formula of paint and have the sprayplate sanded together. This is the most common method. It does not matter how good or poor the grinding performance of a single paint manufacturer for zinc-stearate oil emulsion. The competition within the market allows for the comparability of products, which encourages further development in zinc stearate-emulsion grinder aid. Sanding quality directly affects construction speed, and the frequency at which the sandpaper needs to be changed. In turn, this directly influences furniture producer’s pricing. Most primers contain 5-10% zincstearate-emulsion. Some white textbooks do not have zinc stearate, emulsion or are too expensive for High Grinding. Also, calcium carbonate for quick drying and sanding. It is possible for the Grinding of Zinc Stearate Emulsion to differ between manufacturers. This means that the properties of different materials can be slightly different. A semi-finished product may have a different acid value than the final product. This will influence the quality of the final product. For zinc stearate to emulsion production, stability is key. The grinding process also needs continuous improvement in order improve its performance.
2, Transparency
Transparency in transparent primers directly impacts the aesthetics of the wooden surface. Due to too many impurities, zinc-stearate manufactured by the water process cannot be used for transparent wood lacquers. Direct production of zinc Stearate may be able to satisfy purity requirements but it also requires very high quality. Transparency will be significantly affected by the production process. Transparency might be significantly affected by slight changes in the production process. Although there are many producers of zinc stearate directly, this product is rarely used in the coatings sector. This process is essential for the coating of zinc stearate-based enterprises. For transparency to be determined, disperse some resin, solvent, zinc and standard, then coat the film with a coating agent on glass or black paper.
3, Thickening
The Thickening by zinc stearate is not accepted by the manufacturer. In order to finish the finished product the zinc Stearate Emulsion is added. Thickening occurs when the Viscosity (after dispersing) is greater than 500mP. A thickened zinc stearate solution will cause paint to flow poorly, especially if there are PE coatings.
HTML4_ Oil absorption
Thickening is different from oil absorption. When the amount of added oil is the same, it is possible to absorb significant amounts of oil. However, large viscosities are a sign of high oil absorption. The thickness must not be greater than 500mPas for a period of time. It is rare that oil absorption within PU coatings will have a significant impact on production. There are high demands for oil absorbtion by paint manufacturers. You could think this is because certain paint manufacturers have added more solvents. But, they still need to keep the water from vaporizing. Therefore, some products require high oil absorption. Auxiliary.
HTML5_ 5, Particle size
The measurement of particle size, which is a measure of the size or shape of zinc-stearate particles, is done by measuring their fineness. The easiest test will usually be the one. It is the scraper’s fineness that gives you the most immediate results. It is common to add a little zinc powder to the alkyd solution. You can then adjust the viscosity by adding a solvent, before testing with a scraper meter. Since the resin-coated particle occupies a certain thickness, test results can be slightly more than what is actually fine. But, the test results can still be used to verify that fineness does not exceed the norm as long as they are consistent. Fineness should be maintained in the paint. Too much zinc stearate will create a spray-plate effect. The particles will then be on the surface. But, zinc stearate products do not suffer from such problems.

A lot of manufacturers have mentioned Dispersion as a problem in their paint production. It is normal for zinc stearate to disperse in color. There are indicators that will influence dispersibility. For example, stearic Acid. A high acidity of zinc, high temperatures, or a pressed bag that is not firmly pressed can all lead to poor zinc powder dispersibility. The possibility of crystallization could also arise if the moisture level in the powder zinc is too high. Not good is dispersion. The same goes for zinc stearate, which emulsions are able to solve these issues well.
