Physical properties

Appearance:

The surface is flat and smooth, with rich and varied colors, good gloss and decorativeness, and various colors and textures can be provided according to needs.

Density:

It varies depending on the substrate and coating materials used, but is generally similar to the density of the metal substrate used (such as galvanized sheet, galvanized sheet, etc.), usually around 7.8-7.9g/cm³.

Hardness:

The presence of the coating makes the surface hardness of the color-coated coil higher than that of ordinary metal sheets. Different types of coatings have different hardnesses. For example, polyvinylidene fluoride (PVDF) coatings have a higher hardness and can effectively resist scratches and wear.

Flexibility:

It has a certain degree of flexibility and can be bent, stamped, and processed without cracking or shedding the coating. This makes it suitable for molding of various shapes, such as making roof panels and wall panels for construction.

Thermal properties:

The thermal conductivity is relatively low and has certain thermal insulation properties. In a high temperature environment, it can prevent the rapid transfer of heat to a certain extent, which helps to save energy in buildings. At the same time, different coatings have different heat resistance, such as the heat resistance of silicon-modified polyester (SMP) coating is better than that of ordinary polyester (PE) coating.

Chemical properties

Corrosion resistance:

This is one of the important chemical properties of color-coated coils. The substrate is usually galvanized or galvanized, which has a certain corrosion resistance, and the coating further isolates the metal substrate from the corrosive substances such as air, moisture, acid and alkali in the outside world, greatly improving the overall corrosion resistance. For example, in outdoor environments, color-coated coils can be used for many years without obvious rust.

Weather resistance:

The coating of color-coated coils has good weather resistance and can resist the erosion of natural factors such as ultraviolet rays, rain, wind and sand, and is not prone to fading, powdering, etc. Color-coated coils like polyvinylidene fluoride (PVDF) coatings can still maintain good color and performance under long-term outdoor exposure, and the service life can reach more than 20 years.

Chemical stability:

In general use environments, the coating of color-coated coils is chemically stable and not easy to react chemically with common chemicals. However, in the case of long-term contact with corrosive chemicals such as strong acids and alkalis, the coating may be damaged, thus affecting its protective performance.

Flammability:

Color-coated coils with different types of coatings have different flammability. Generally speaking, color-coated coils with ordinary polyester coatings are flame-retardant materials. When encountering open flames, they will burn to a certain extent, but the burning speed is slow, and they will extinguish themselves after leaving the fire source. Some special fire-retardant coating color-coated coils have better flame retardant properties and can effectively delay the spread of fire.

Applications:

Color coated coil is widely used in various fields. It is used for roofs and walls in buildings, which are both protective and beautiful; it is used as refrigerator and air conditioner shells in the home appliance field to improve the texture; it is used for cabinets and wardrobe panels in furniture manufacturing; it is used to cover the surface of automobile bodies and containers in the transportation industry; it is also used for billboards, ventilation ducts, etc., with its colorful appearance and corrosion resistance, it can meet diverse needs.
