Product description
Powder coatings have become one of the most environmentally friendly coating systems due to their complete absence of organic solvents and low VOC (volatile organic compound) emissions during curing. According to experts from China Epoxy Resin Industry Association, electrostatic powder coatings will be developed more and more rapidly in the 21st century. In 2010, powder coatings will occupy 20% of the total industrial coatings. Optimizing the formula design and improving the construction process of powder coatings to improve their leveling performance is of great and ideal significance to its market development. In this context, a large number of discussions on dealing with the poor leveling defects of powder coatings have arisen. A study recently proposed that UV-curable powder coatings are an effective way to improve film leveling.
The so-called leveling property of the coating refers to the smooth and lubricating state of the coating film after the coating is applied. The surface with good leveling property should not have irregularities such as orange peel, brush marks, ripples, and shrinkage cavities. Experts from China Epoxy Resin Industry Association said that the method of direct observation with the naked eye is to compare the sample and the standard sample in parallel to judge the leveling of the coating film. This method varies from person to person and is more objective. powerful. The wavelength scanning method used in the automobile industry is used to characterize the surface state of the coating film, which has a semi-quantitative effect. Long-wave (10-0.6 mm) and short-wave (0.6-0.1 mm) are used for scanning, and the measurement value is between 0 and 100. The lower the value, the smoother the surface of the coating film and the better the leveling.
