INTRODUCTION OF FLUOROCARBON POLYESTER COATING
fluorocarbon coating, also known as fluorocarbon paints, fluorine paints, fluororesin paints, etc., refer to paints that use fluororesin as the main film- forming material.
Among various coatings, fluororesin coatings have high electronegativity due to the introduction of fluorine, and strong fluorocarbon bonds, and have particularly
superior properties such as weather resistance, heat resistance, low temperature resistance, and chemical resistance. And has a unique non- stick and low friction.
It is the coating brand with the highest comprehensive performance after high- performance coatings such as acrylic paints, polyurethane coatings and silione
coatings. After decades of rapid development, fluorine coatings have been widely used in various fields such as construction, chemical industry, electrical and
electronic industry, machinery industry, aerospace industry, and household goods. At present, the widely used fluororesin coatings mainly include PTFE, PVDF and
PEVE. It should be noted that the fluorocarbon paint should be placed in a place that is dry, waterproof, leakproof, sunscreen, high temperature resistant, and away

The fluorocarbon spraying process is
Pre-treatment process: degreasing and decontamination of aluminum→washing→caustic washing (degreasing)→washing→pickling →
washing→chromizing - * washing - + pure washing
Spraying process: spray primer - + top coat -→varnish→baking (180-250° C)→quality inspection
The multi-layer spraying process uses three sprays (referred to as three sprays), sprays primer, topcoat and varnish and secondary spray
(primer, topcoat). .
(1) first coating = top coat
(2) Second coating = primer + topcoat;
(3) third coats = primer + top coat + varnish;
(4) Forth coats = primer + barrier paint + topcoat + varnish.
1、Excellent anti- corrosion performance - Because of excellent chemical inertness, chemical resistance of acid, alkali, salt and other chemical
substances and a variety of chemical solvents, it provides a protective barrier for the substrate; the film is tough - high surface hardness, It is
resistant to impact, buckling and abrasion, and exhibits excellent physical and mechanical properties.
2、Maintenance-free, self- cleaning - fluorocarbon coating has extremely low surface energy, surface dust can be self- cleaning by rain, excellent
hydrophobicity (maximum water absorption is less than 5%) and oil repellency, very small friction coefficient (0.15-0.17), it will not stick to dust and
scale, and it has good antifouling properties.
3、Strong adhesion-lt has excellent adhesion on the surface of metals such as copper, stainless steel, polyester, polyurethane, viny| chloride,
cement, composite materials, etc., and basically shows the characteristics that should be attached to any material. . Highly decorative - in a 60
degree gloss meter, it can achieve a high gloss of more than 80%.
4、Ultra-long weather resistance- The coating contains a large amount of F--C bond, which determines its super stability, no powdering, no fading,
and a service life of up to 20 years. The excellent performance and workability more than any other type of coating - two- component packaging, long
storage period and convenient construction.
1. Compared with traditional paints, it has better light resistance and weather resistance;
2. Compared with the traditional exterior wall- mounted aluminum- plastic composite panel, the operation is simpler and easier to renovate;
3. The cost is much lower than that of the aluminum- plastic panel, and the same effect can be achieved;
4. The light weight will not impose a heavy burden on the wall, and there is no danger of the aluminum composite panel flling.
