Color steel coil colorful, its color is processed by different colors of paint, so what should be paid attention to when choosing paint for color steel coil?

1, the production of color steel coil coating is basically composed of four parts, that is, resin, pigment, solvent, additives. Among them, the solvent is volatile, and its three parts are basically non-volatile.
2. The requirements for these coatings are that the resin, as a film-forming substance, is quite stable during the coating storage period, without significant physical and chemical changes, and can be rapidly cured into a film under specified conditions.
3, a wide variety of resins, commonly used in coil coating resins are acrylic resin, epoxy resin, polyester resin and polyurethane resin.
4, the pigment must be used with the resin, the main role in the paint is to color the film, the pigment ratio will affect the hardness of the film, gloss and corrosion resistance.
5, solvent is an important part of the production of color steel coil liquid paint, in the paint drying process is volatile components. The solvent has a great influence on the coating production, storage, coating, film formation and film forming quality of color steel coil.
