What is the paint for color coated boards made of? What role do they play? Color coated board coatings are usually composed of resins, pigments, solvents, additives and other auxiliary materials. Now Jinan Color Steel Plate Factory will answer for you.
The additive used for color steel plate is a small amount of additive added to improve coating performance. The amount of additive in the coating is small, but the effect is significant. For example, some can improve the performance of the coating and film, some can shorten the drying time, and some can prevent the film from becoming ill conditioned. There are many kinds of additives, including desiccant, curing agent, leveling agent, defoamer, matting agent, stabilizer, etc.
Almost all liquid coatings are composed of some raw materials, mainly resin, which is indispensable for any coating. It can be said that resins (sometimes containing solvents and additives) are transparent coatings, and then pigments are added to form coatings of various colors.
Resin is the film-forming material of the coating and the basis of the coating. It has the function of bonding other components in the coating and forming the film, and plays a decisive role in the performance of the film. The polyester and fluorocarbon we often say refer to the resin of paint.
Pigment is the main component of colored paint, which can make the film present color, enable the film to cover the substrate, and mainly play the role of decoration and protection.
The solvent mainly plays the role of dissolving and uniformly dispersing the film-forming materials to facilitate painting, which is also known as the thinner. After high-temperature curing, the solvent will volatilize into the atmosphere.
Auxiliaries refer to the auxiliary materials of coatings, which can improve the performance of coatings or coatings in a specific direction. For example, the antibacterial coatings we mentioned previously need to add antibacterial additives to the coatings to make the coatings have certain antibacterial and bacteriostatic properties.
The color coated plate is light in weight, beautiful in appearance, good in anti-corrosion performance, and can be directly processed. It provides new raw materials for the construction industry, shipbuilding industry, automobile manufacturing industry, furniture industry and electrical industry, with good effects of replacing wood with steel, high-energy construction, energy conservation and pollution prevention.
