Epoxy-Polyester Hybrid Powder Coating (Hybrid Type ) is a thermoset coating system that combines epoxy resin and polyester resin to give you balanced mechanical performance, reliable adhesion, and stable decorative appearance. This hybrid structure integrates the corrosion resistance and bonding strength of epoxy with the improved surface finish and processing stability of polyester.
When you select Epoxy-Polyester Hybrid Powder Coating (Hybrid Type ) , you obtain a cost-effective indoor coating solution suitable for general metal components where both appearance and functional durability are required. It is widely used in commercial and light industrial applications that demand consistent quality and production efficiency.
You can apply this hybrid powder coating to a wide range of indoor metal products, including:
Office furniture frames and cabinets
Indoor appliances such as washing machine panels and refrigerator back panels
Lighting fixtures and housings
Shelving systems and storage racks
Electrical enclosures for indoor use
General fabricated metal parts
Typical coated test samples include cold-rolled steel panels, appliance housings, tubular steel frames, and sheet metal assemblies prepared with proper surface pretreatment.
This coating is recommended primarily for indoor environments where balanced corrosion resistance, decorative finish, and economic efficiency are required.

With this hybrid system, you achieve an effective combination of performance, aesthetics, and production efficiency for general indoor metal components.
In an office furniture manufacturing project, Epoxy-Polyester Hybrid Powder Coating (Hybrid Type ) was applied to steel cabinets and shelving frames intended for indoor commercial use. The customer required a satin finish with uniform color consistency across large production batches.
After coating at an average film thickness of 80 μm over properly pretreated steel, adhesion testing according to ISO 2409 and impact resistance testing according to ISO 6272 confirmed stable mechanical performance. Salt spray testing in accordance with ISO 9227 demonstrated adequate indoor corrosion resistance. The coating delivered consistent appearance and reduced production cost compared to higher-performance exterior systems.
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.
