What is powder coating?
Powder coating is an industrial coating consisting of powdered pigments and curing agents. It is usually heat-cured to form a solid coating and is widely used on different types of items such as metal surfaces, plastic surfaces, wood surfaces, etc. The advantages of powder coatings include: good adhesion, corrosion resistance, wear resistance, environmental protection, effective, etc. Therefore, it is widely used in the coating protection of industrial products, furniture, automobiles and other fields.
Application field
Powder coatings are widely used in industrial products, furniture, automobiles and many other fields. The main applications are as follows:
Metal surface coatings: used to protect metal surfaces from corrosion, wear, pollution, etc.
Plastic surface coatings: used to improve the appearance, protective performance, durability, etc. of plastic surfaces.
Wood Surface Coatings: Used to protect wood surfaces from insects, water stains, heat deformation, etc.
Furniture coatings: used to improve the appearance, durability, stain resistance, etc. of furniture surfaces.
Automotive coatings: used to protect the surface of the car from UV rays, weather, etc.
Electronic product coatings: used to protect the surface of electronic products from pollution, abrasion and other effects.
Other applications: It can also be used on the surface of buildings, agricultural machinery, medical equipment, etc.
The above are the main applications of powder coatings. With the continuous development of science and technology, the application fields of powder coatings are still expanding.
Powder coating performance testing
Surface Gloss: The smoothness and glossiness of a surface.
Surface Roughness: The flatness and roughness of the surface.
Weather resistance: the resistance of the coating to ultraviolet rays, climate, temperature and other factors.
Corrosion resistance: the resistance of the coating to chemical substances, salt rain and other corrosive factors.
Wear resistance: the resistance of the coating to factors such as friction and wear.
Flexural Strength: The flexural strength of the coating under bending conditions.
Tensile Strength: The tensile strength of the coating under tension.
Elastic modulus: The change in elasticity of the coating when it deforms.
Conductivity: the conductivity of the coating to the current.
Adsorption: The ability of the coating to absorb physical and chemical substances.
The above are common items for powder coating performance testing, and the actual testing content may vary due to different manufacturers, use environments, requirements, etc.
