Color steel tiles have been exposed to the wind and the sun for a long time. After the surface paint layer is aged, it will turn white and powdery. The oxygen in the air directly contacts with the substrate, causing rust, so it needs to be painted and renovated. What kind of paint should be used for color steel tile painting and renovation? Next, Jinan Color Steel Tile Factory will explain it to you.
The paint used for painting and refurbishment of color steel tiles is generally ordinary paint. If conditions permit, it is better to use the special paint for refurbishment of color steel tiles, because the hardness of the special paint for refurbishment of color steel tiles is better, and the overall color is beautiful, and the effect is better. The paint used for refurbishment of color steel tiles is divided into primer and finish paint:
The alkyd iron red primer is composed of refined dry vegetable oil, modified alkyd resin, iron oxide red and other antirust pigments, pigments, dispersants, anti settling agents, driers, solvents, etc. The wet film thickness is 40 microns, and the dry film thickness is 25 microns. The coating method is high-pressure airless spraying, brushing, and roller coating.
Acrylic topcoat is adopted. Acrylic paint is made by synthetic reaction grinding of styrene resin, polyacrylate, polyester resin, chlorinated rubber, curing agent, leveling agent, defoamer, high filler, etc. Wet film thickness: 45 μ m, dry film thickness: 30 μ m, coating method: brush coating, spray coating, roller coating.
In addition, in general, the painting price for color steel tile renovation is mainly determined according to the corrosion degree and painting times of color steel tile. For example, some of the color steel tiles in the customer's factory are severely rusted, some are only slightly corroded, some are leaking, and some only need to be painted. Therefore, it is difficult to have a standard price in this case, which should be based on the customer's requirements and the actual situation on the site, The quotation shall be made according to the color steel tile renovation construction plan.
