Coating is a technique for applying organic compounds to base metals. It gives the metal a good luster and protects it from corrosion. The coating thickness is typically 10+5m (top coat + back coat). For specific applications, it can be adjusted to 35m length.
Polyester (PE), silicone modified polyester (SMP), high durability polyester (HDP) and polyvinylidene fluoride (PVDF) are four of the most popular coatings (PVDF). The properties and applications of the coatings vary. For your convenience, additional information is provided below.
PE sheets are easy to use and adhere well. You can pick from a variety of shades. In addition, it is the most cost effective of several coatings. However, it has very low UV resistance. Therefore, the use of PE coating is limited. It has a service life of 7-8 years.
PE Coating Coils
Attractive
Easy to process
Cost-effective
Poor corrosion resistance
PE is often used as a primer because of its excellent adhesion. Although it has a low corrosion resistance, it is not suitable for use in corrosive environments.
In addition to chemical resistance, mechanical properties, UV resistance and heat resistance are excellent. It is the most well-protected of the three. Its corrosion resistance can last up to 20 to 25 years in normal settings.
Excellent heat resistance
Excellent mechanical properties
Good resistance
PVDF / FEVE - Coated Aluminum Coil
Due to its superior corrosion resistance and UV resistance, it is commonly used in chemical facilities, power plants, high speed railway stations, etc.
1. Paint types: As mentioned earlier, there are several paint types to choose from. You can choose the most cost effective option that best meets your requirements.
2. Paint brands: There are several paint brands to choose from, including Nippon, Akzo Nobel, and others. You can choose the one you want according to your budget.
3. Coating thickness: Coating thickness has an effect on durability and heat resistance. PVDF coating requires a thicker coating film, which increases the durability of steel products. This is the most effective. If the environmental conditions are not good, this is a good location for your project.
4. Coating color: For structures, color is the most important consideration. Your decision is largely influenced by the surrounding environment as well as your personal preferences. In addition, light-colored coatings have a higher thermal reflectivity. When dark colors are exposed to UV radiation, they fade quickly.
