In recent years, there are many brands in the domestic paint market, but there are not many brands that are influential nationwide and have won consumer recognition. Powder coating, as an indispensable coating in paint coatings, plays an important role in metal facilities and buildings, because it can play a role in anti-corrosion of metals, thus extending the service life of non-ferrous metals. Then, let's introduce the types and characteristics of powder coatings.

Type of powder coating

    Powder coating is different from general coating, it exists in the form of fine powder. Because it does not need solvent, it is called powder coating. Powder coatings are natural, harmless, efficient, resource saving and environmentally friendly.

    Although the varieties of powder coatings are not as diverse as solvent based coatings, there are also many polymer resins that can be used as powder coatings. Generally, it can be divided into two categories: outdoor and indoor.

Indoor powder coating

1. Pure epoxy powder coating

    Pure epoxy powder coating is a powder coating product made of high molecular weight epoxy resin and curing agent. Excellent adhesion, impact resistance, surface hardness, toughness, adhesion and other mechanical properties. High gloss, high flow, good painting effect, good chemical resistance and corrosion resistance, good electrical insulation, high baking temperature, long time easy to yellowing, can not be used for outdoor products. It is applied to steel bars, water pipes, valves, cylinders, agricultural machinery, steel structures, electromechanical equipment, instrument casings, motor rotors, and household, anti-theft doors, industrial equipment, fitness equipment, etc.

2. Epoxy polyester powder coating

    Epoxy polyester powder coating is a powder coating made of epoxy resin and polyester resin as the main raw materials. It has good decoration and thermal stability, and is generally not suitable for outdoor or places with weather resistance requirements. The variety and color of this product are rich and colorful, including high gloss, matt, matte, pattern, wrinkle, metal and other color products. It is applied to various hardware accessories, household appliances and medical equipment, automobiles, motorcycles, new energy vehicles, agricultural machinery, engineering machinery accessories, chassis and cabinets, various furniture, etc. This product is not recommended for outdoor weather resistant products.

Outdoor powder coating

1. Pure polyester powder coating

    Pure polyester powder coating is a kind of powder coating specially designed for outdoor weather resistance. It has good outdoor weather resistance and color stability and is widely used in outdoor building materials machines. This product is rich in variety and color, including bright, flat, matt, sand grain and other products, and can also be designed according to customer requirements. It is applied to aluminum profiles for construction, automobiles, motorcycles, new energy vehicles, agricultural machinery, engineering machinery, road barriers, external fitness equipment and competition equipment, as well as metal surfaces with weather resistance requirements.

Characteristics of powder coatings

1. Powder coating does not contain toxic, solvent and volatile substances;

2. The utilization rate of raw materials is high, and the highest utilization rate can reach more than 90%;

3. Powder coating can be applied at one time, and the coating film with sufficient thickness can be obtained without primer, which is simple to operate, high in production efficiency, and can reduce costs;

4. Powder coating has good adhesion, impact resistance and toughness, and has excellent chemical corrosion resistance and electrical insulation performance;

5. Powder coating is easy to store, safe and convenient to transport.
