When the commonly used saturated polyester resins, epoxy resins and other materials are above 350°C, the carbon-oxygen bonds will be broken and decomposed very quickly, and the coating will be powdered and scattered. They are usually called the three primary colors.. Although the colors are very different, the basic colors are only red, yellow, and blue. Pigments and fillers are the link that affects the performance of high-temperature coatings. They are stable in storage at room temperature.
Low-temperature curing powder coating is a new type of solvent-free solid powder coating, which is completely different from ordinary coatings. The main component is resin, and the result of powder coating surface spraying will be better than that of paint. Therefore, this product is non-toxic, non-solvent, and non-toxic and volatile, so the powder coating is non-toxic, non-fire, and non-‘three wastes’Wholesale Indoor metal furniture powder coatings emissions, and meets the requirements of the national environmental protection law.
The low-temperature curing powder coating is too fine or the powder is damp and agglomerates, causing powder to accumulate in the spray gun. The purchased powder or the powder itself is of poor quality. In the production process of powder coatings, various liquid chemical additives such as harmful film-forming, evacuation, dampness, leveling, anti-corrosion and anti-mildew are omitted.
The formula of powder coatings is mainly as follows: resin and its curing agent, which is the base for coating film formation; additives, used to improve the surface or various properties of the coating; pigments, to give the coating concealment and color; fillers, mainly It is the benefit of physical enhancement. The two primary colors are mixed with each other in equal amounts to form a secondary color (intermediate color), and the secondary color and the primary color are mixed with each other in equal amounts to become a complex color.
