What is the purpose of mixed powder coating
source：www.cnjindu.com | Release time：2026年05月08日1、 Core use (mainly indoor)
Household appliance casing: metal panels for washing machines, refrigerators, microwave ovens, rice cookers, and water heaters, with a smooth coating, oil resistance, and easy cleaning.
Metal furniture/office equipment: Steel filing cabinets, shelves, tables and chairs, metal bed frames, bookshelves, balancing decoration and rust prevention.
Hardware tools/electrical equipment: electric tool housings, distribution boxes, meter boxes, transformer housings, valves, fittings, with good insulation and anti-corrosion properties and mechanical strength.
Automotive/motorcycle parts (indoor/chassis): wheel hub primer, frame, engine hood inner parts, chassis parts, resistant to oil stains, salt spray, strong adhesion.
Fitness equipment/radiators: treadmills, dumbbell stands, radiators, sweat resistant, heat-resistant, and impact resistant.
Instrumentation/Building Materials Interior: Instrument shell, indoor lighting fixtures, metal door and window frames, decorative profiles, delicate high gloss/matte, strong decorative value.
2、 Key performance (suitable for the above purposes)
Strong adhesion: The metal substrate is not easy to peel off or peel off.
Good leveling and beautiful appearance: high gloss/matte/sand pattern, suitable for decorative surfaces.
Excellent mechanical performance: impact resistance, flexibility, wear resistance, and not easily scratched during transportation and use.
Medium anti-corrosion: Good rust prevention in damp indoor environments with general acidity and alkalinity (salt spray for about 500 hours).
High cost-effectiveness: The price is lower than pure polyester, and the comprehensive performance is better than pure epoxy.
3、 Difference from pure epoxy/pure polyester
Pure epoxy: stronger anti-corrosion/insulation, poor leveling and weather resistance, commonly used in pipelines, chemical equipment, and insulation components.
Mixed type (epoxy polyester): Balanced type, indoor decoration+medium anti-corrosion, most widely used.
Pure polyester: extremely weather resistant, suitable for outdoor use (building curtain walls, street lights, outdoor furniture).
4、 Overview of Typical Application Scenarios
Indoor metal parts, requiring decoration+rust prevention+cost control → choose a hybrid type.
Outdoor, long-term sun exposure → choose pure polyester.
Heavy anti-corrosion, chemical/insulation environment → choose pure epoxy.
