Application of Zinc Stearate Emulsion in Coatings

Zinc Stearate is a common “zinc soap” used widely in modern industries. It is, therefore, used as a form of soap. 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. It is used primarily in the rubber and plastic industries.

This emulsion of zinc stearate is used primarily in wood coatings as it can fill holes and improve the sanding. This paint offers excellent Transparency. It can also affect Transparency when used with transparent primers. 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 Tearate Emulsions Have Several Technical Indicators in the Wood Primer that can affect the Paint’s Performance:

1, Grinding

A key indicator is the Inwood primer’s sanding capability. The common method of testing is to use the same formulation of paint and have the spray plates sanded simultaneously. This is because there is no set standard. There is no way to tell if the grinding quality is bad or good if you only use one brand of zinc-stearate oil emulsion. Competition in the marketplace encourages the evaluation of different products, and further development of the Zinc Stearate Emulsion Grinding Aid. A furniture manufacturer’s costs will be directly affected by the quality of its sanding performance. Its speed can directly impact the time it takes to build a piece of furniture. The general rule of thumb is that the primer contains between 5-10% zincstearate. The primer is usually 5-10%. However, white textbooks with low grinding requirements and low prices do not contain zincstearate. 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 the various materials can be slightly different. A semi-finished product may have a different acid value than the finished 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 wood’s aesthetics. 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 affected greatly by the production process. Transparency might be significantly affected by slight variations in the production process. It’s rare that zinc stearate is used in the coatings sector, even though there are many suppliers. This process is essential for the coating of zinc stearate-based enterprises. For transparency to be determined, disperse some resin, solvent, zinc and standard samples, then coat a thin film of black and white paper (or glass) with an applicator.

3, Thickening

The zinc stearate solution emulsion is too thick for coatings. In order to finish the product, the Zinc Stearate Emulsion is added onto the surface. Thickening occurs when the Viscosity (after dispersing) is greater than 500 mP. A thickened zinc stearate solution will cause paint to flow poorly, particularly for 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. The final product has a high viscosity. 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 an instant result. 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, as long the standard remains comparable and is repeatable, you can use the test to see if fineness exceeds norm. Fineness should not exceed 2% in the paint. The spray plate will reflect the zinc stearate particles, while unevenness will occur on areas not polished. But, zinc stearate products do not suffer from such problems.

6, Dispersion

Many paint producers also mention dispersion during their production processes. 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 dispersibility. Crystallization problems may develop 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.
