Due to the good application prospects and advantages of MDF powder coating technology itself (see attached table), it has long been one of the main development directions of the powder coating industry and even the entire furniture industry. Standard has invested heavily in research and development in this field. At present, MDF technology has basically matured and has the conditions for large-scale promotion and application. And it is creating more and more efficient and fast construction efficiency, creating greater value for customers. With the increasing awareness of environmental protection and health, the relevant environmental protection laws and regulations are becoming more and more stringent, which will greatly expand the application field or space of powder coatings.
| Project | Powder coating | Liquid coating |
|---|---|---|
| Economical | Low overall cost (coating + labor + energy consumption + storage), powder coating overall cost 80-150RMB/m² | Low overall cost (coating + labor + energy consumption + storage), liquid coating overall cost 200-150RMB/m² |
| Environmentally friendly | Construction environment, no volatility, no odor, no sewage; finished product zero VOC, and can effectively seal harmful substances in the board, healthy and environmentally friendly. Coatings can almost 100% utilize | High VOC, up to 31 kinds of chemical poisons volatilize, especially highly toxic substances such as benzene, toluene, xylene and diisocyanate. The effective utilization rate of the coating is low, and formaldehyde is released in the later stage. |
| Process limitations | Can handle special-shaped parts; convenient for the plate to handle chamfers and chamfers, the product is more beautiful and durable | The process is complex, 6-10 processes, and cannot handle special-shaped workpieces. Special edge sealing treatment is required in the later stage, and it is easy to crack |
| Coating efficiency | Fast curing speed, simple process: 1-2 processes take 2-4 hours to construct, low storage space requirements | Complex process, 6-10 processes, construction time is 6-12 days, and more labor is occupied. Slow curing speed, high storage space requirements |
| Coating performance | Excellent coating performance, good chemical and solvent resistance, can effectively seal formaldehyde | Coating performance varies greatly according to different varieties. Poor water resistance, wear resistance and chemical resistance, poor sealing of volatile substances such as formaldehyde |
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.
