PVF steel drum coating is mainly used for packaging containers of chemical pesticide products, inner walls of cans and other special anti-corrosion fields.
(PVF) coating is the abbreviation of polyvinyl fluoride (Polyvinyl Pluoride). The coating is made by grinding and processing with high molecular resin. It has many common characteristics of carbon-fluorine materials and has unique weather resistance.
(PVF) fluorine coating belongs to crystalline polymers. It is insoluble in solvents at room temperature. It can only be made into organic solvent dispersions with the help of additives and needs high-temperature baking to form a film. Therefore, it is found that it can only be wiped off by using solvents before high-temperature baking before film formation. After film formation, it is insoluble in solvents.
1. Corrosion resistance. It has excellent anti-corrosion performance for various oils, alcohols, ketones, esters, salts, alkalis, dilute acids and other chemical pesticide products. At present, it has been tested that it can contain more than 100 kinds of chemical products.
2. Outstanding weather resistance, heat resistance and low temperature resistance, long-term use temperature is -70~110℃
3. It has anti-humidity, anti-mildew and anti-salt spray performance.
4. The coating has good flexibility, resistance to disassembly, wear resistance and impact resistance.

Powder coatings can be categorized by resin system (epoxy, polyester, hybrid, polyurethane), appearance (smooth, texture, hammer, metallic, pearlescent), or performance level (anti-corrosion, heat-resistant, UV-resistant, architectural grade, automotive grade).
Powder coatings offer thousands of colors in gloss, matte, satin, metallic, candy, texture, wrinkle, hammer tone, wood grain, fluorescent, and other custom effects. Special powders can create soft-touch, anti-scratch, anti-fingerprint, or anti-graffiti surfaces.
The process generally includes surface pretreatment (degreasing, phosphating, chromating, sandblasting), drying, electrostatic spraying, curing in an oven, and cooling. A well-controlled pretreatment and curing process ensures strong adhesion and long service life.
Powder coatings are environmentally friendly, solvent-free, and produce minimal waste. They offer excellent corrosion resistance, weather durability, mechanical strength, and uniform film appearance. The coating is tough, impact-resistant, scratch-resistant, and has a long lifespan.
Powder coatings are widely used in appliances, aluminum profiles, architectural components, automotive parts, bicycles, furniture, outdoor equipment, machinery, electrical cabinets, pipeline systems, and general industrial and consumer goods.
Powder coating is a dry finishing technology where finely ground powder is electrostatically sprayed onto a metal or non-metal surface and then cured at high temperature. After curing, the powder melts into a continuous, durable, and decorative coating layer.
Powder coating protects the substrate from corrosion, weathering, chemical attack, and mechanical wear. It also provides decorative appearance with rich colors, gloss levels, textures, and special effects.
In many industrial applications, powder coating outperforms liquid paint. It forms a thicker and tougher coating, resists corrosion and chemicals better, and does not contain VOCs. It also provides excellent consistency and cost-effective mass production.
It is called powder coating because the coating material is a solid powder instead of a liquid paint. The coating is formed by melting and curing powder particles under heat.
Powder coatings include several families depending on resin chemistry:
• Epoxy powders
• Polyester powders
• Epoxy-polyester hybrid powders
• Polyurethane powders
• Acrylic powders
• Fluorocarbon (PVDF) powders
Each type has its own performance features such as corrosion resistance, UV resistance, chemical resistance, outdoor durability, or decorative properties.
Powder coatings are based on thermoset or thermoplastic resins combined with pigments, curing agents, fillers, additives, and in some cases metallic or effect particles. Common substrates include steel, aluminum, galvanized metal, MDF, and certain heat-resistant plastics.
The lifespan depends on powder type, film thickness, application method, pretreatment, and service environment. Indoor coatings can last more than 10–20 years. High-grade outdoor polyester or fluorocarbon powders can last 15–25 years or longer under UV exposure.
