PE polyester color steel plate product introduction

PE coating has good attachment to the material, color steel plate is easy to process and form, cheap and many products, and the choice of color and luster is large. In the general environment of direct exposure, the substrate corrosion protection life can be as long as 7-8 years, but in the industrial environment or heavily polluted areas, its service life will be relatively reduced, and polyester paint resistance to ultraviolet light and coating chemical resistance is not ideal, so the use of PE paint is still subject to a number of restrictions, generally used in areas where air pollution is not serious or need multiple molding processing products. Baosteel PE polyester color steel plate can be used up to 7 in one strand environment

HDP high weather resistance color coating product introduction

HDP high weather resistant color coating board using EDP polyester paint, good durability, the use of high molecular weight resin, polymer branch chain less, stable bond energy, not easy photolysis, so not easy to powder, gloss drop high. The main properties of high weather resistance polyester are high weather resistance and strong corrosion resistance, mainly used in areas with long sunshine time, high dryness, or large temperature difference between day and night, and relatively harsh humidity. A wide range of uses. It belongs to the high-end products of color coated sheet roll. The coating thickness is generally 5UB oxygen resin primer +20UM HDP polyester top paint on the front, and 50 epoxy resin primer +6UPE resin top paint on the back. In the synthesis of high weather resistant polyester resin, monomer containing cyclohexane structure is used to achieve the balance of flexibility, weather resistance and cost of the resin, the use of non-aromatic polyyeast and polyacid to reduce the resin's absorption of four rays to achieve high weather resistance of the paint, and the UV absorber and steric amine are added to the coating formula to improve the weather resistance of the paint film. The coating has been widely recognized in foreign markets and is a very cost-effective type of coating.

PVDF fluorocarbon color coating product introduction

Fluorocarbon color steel plate (PVDF) color coated plate Chinese scientific name polyvinylidene fluoride color coated plate, is the use of high-end polyvinylidene fluoride resin. Due to the strong bond energy between the chemical bond and the chemical bond of PVDF, the coating has very good corrosion resistance and color retention. In the color coated steel plate coating for the construction industry, it is a better product, and the molecular weight is large and it is a straight bond structure, so in addition to chemical resistance, mechanical properties, ultraviolet resistance and heat resistance are also very special. In the general environment, the base corrosion protection life can reach 20-25 years.

In recent years, the prevalence of fluorine-containing tree esters with trifluorinated vinyl chloride and vinyl ester monomer copolymerization in China has begun, and a large number of them are used in the external walls and metal plates of the building area, because the content of ethylene ester monomer and fluorine that is easily hydrolyzed is lower than PVDP (about 30%), so there is a certain gap between the basic weather resistance and PVDF. Our company supply Baosteel, Ye Hui, United and other domestic large steel production of fluorocarbon coating, the coating PVDF content is not less than 70% (other acrylic acid resin) PVDF fluorocarbon color steel plate, provide 20 years of quality guarantee, guarantee in 20 years the coating does not fall off, do not powder, do not crack, do not fade.
