0.75mm Pre-finished PPGI Textured Matt Prepainted Galvanised color-coated Steel Valspar for roof
HDP high weathering color coated plate adopts HDP polyester coating, good durability, adopts high molecular weight resin, polymer branch chain is less, the bond energy is stable, not easy to photolysis so it is not easy to chalking, gloss drop high.
HDP color steel plate at the same time using inorganic ceramic pigments, in daylight is not easy to fade. The most important performance of high weather resistance polyresin is high weather resistance and strong corrosion resistance, mainly used for long sunshine time, high dryness, or large temperature difference between day and night, humidity is more harsh areas. It is widely used.
As the resin molecular structure of high durability polyester is different from that of common polyester, with fewer polymer branched chains, stable bonding energy and not easy to be photolysed, the product has excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good adhesion of the paint film, rich in color, and high cost performance.
Product features
- Better durability, performance between ordinary polyester (PE) and fluorocarbon (PVDF);
- Good corrosion resistance;
- Good UV resistance.
