HDP Polyester Coated Aluminum Coil Stock White Aluminum Trim Roll

Coated Aluminum Coil Manufacturers, Providing High-quality Sheets

Product Introduction:

coated aluminum coil uses HDP polyester coating, which has good durability, high molecular weight resin, few polymer branches, stable energy, not easy to photolyze, so it is not easy to powder and has high gloss. The main performance of high weather-resistant polyester is strong weather resistance and corrosion resistance. It is mainly used in relatively harsh areas with long sunshine time, high dryness, large temperature difference between day and night, strong humidity, etc., and has a wide range of uses. It is a high-end product of color-coated aluminum coil. The coating thickness is generally 5um epoxy resin primer + 20um HDP polyester topcoat on the front side, and 5um epoxy resin primer + 5um PE resin topcoat on the back side.

The high weather-resistant polyester resin uses monomers containing cyclohexane structure during synthesis to achieve a balance between the flexibility, weather resistance and cost of the resin, and uses non-aromatic polyols and polyacids to reduce the resin's absorption of UV light to achieve high weather resistance of the coating, and adds ultraviolet absorbers and histamines to the coating formula to improve the weather resistance of the paint film. This coating has been widely recognized in the foreign market and is a type of coating with outstanding cost performance.

The following is a detailed introduction:

Performance characteristics:

Excellent weather resistance: high molecular weight resin is used, the polymer has few side chains, stable bond energy, and is not easy to photolyze, so it is not easy to powder and reduce gloss.

Not easy to fade: inorganic ceramic pigments are used, the color stability is good under sunlight, it is not easy to fade, and it can maintain a beautiful appearance for a long time.

Good adhesion and flexibility: the coating has good adhesion to the aluminum coil substrate, and the paint film has good flexibility, and it is not easy to have problems such as coating shedding during the processing and molding process.

Service life: Compared with ordinary polyester color-coated aluminum coils, HDP color-coated aluminum coils have a longer service life, and the general warranty period is more than 15 years. If the coating is 2 coats and the film thickness reaches 20μm, under the appropriate use environment, the coating can be achieved within 15 years without shedding or powdering.

Compared with other coatings: Compared with ordinary polyester (PE) color-coated aluminum coils, HDP color-coated aluminum coils have better weather resistance and are relatively expensive; compared with polyvinylidene fluoride (PVDF) color-coated aluminum coils, HDP color-coated aluminum coils are slightly inferior in weather resistance, but have lower costs and can meet the durability requirements of medium and high-end buildings, with a high cost-effectiveness ratio.

Applications:

HDP color-coated aluminum coils are widely used in many fields due to their excellent weather resistance, color stability and processing performance. The following is a specific introduction to the use of its products from different industries:

Exterior wall decoration: used for the exterior curtain walls of large public buildings such as factories, office buildings, commercial complexes, airport terminals, gymnasiums, etc., which can resist ultraviolet rays, wind and rain erosion, and maintain long-term beauty.

Roofing and ceiling: suitable for the roofs and indoor ceilings of industrial plants, warehouses, and logistics centers, with good weather resistance and waterproof performance, reducing maintenance costs.

Indoor decoration: such as interior wall decorative panels and elevator car panels of shopping malls and hotels, which can enhance the texture of space by customizing colors and surface effects (such as metal texture and wood grain).

Decorative materials: integrated ceilings, skirtings, blinds, etc., which are both beautiful and practical, and can be customized in a variety of colors to match home decoration styles.

Outdoor facilities: billboards, bus stop ceilings, outdoor signboards, etc., which can maintain bright colors and reduce fading and chalking after long-term exposure to the outdoors.

Application advantages compared with other materials:

The uses of HDP color-coated aluminum coils cover multi-dimensional scenarios from construction to civil use. Its core advantage is to provide weather resistance higher than ordinary coatings at a moderate cost to meet long-term use needs.
