What is the purpose of metal bound powder coating
source：www.cnjindu.com | Release time：2026年08月08日Core two functions: metal texture decoration+substrate anti-corrosion protection, and also compatible with electrostatic spraying production lines. Recycled powder can be reused normally.
1、 Core purpose
1. Decorative alternatives to electroplating and anodizing (primary use)
Realize the appearance of metallic glitter such as silver gray, champagne gold, antique bronze, and sparkling silver, with an effect similar to metallic paint; Ordinary dry mixed metal powder spraying is prone to yin-yang and flower formation, and the bound powder has stable color difference and good batch consistency.
The spraying effect of new powder and recycled powder is almost the same, and the recycled powder can be used normally, which cannot be achieved with dry mixed metal powder, greatly reducing production costs.
Avoid defects such as separation of metallic pigments, powder accumulation in spray guns, and uneven color depth in certain parts of the workpiece.
2. Substrate protection (anti-corrosion, wear-resistant, weather resistant)
According to different resin systems:
Pure polyester/TGIC system (outdoor version): UV resistant, aging resistant, used for outdoor components, with excellent salt spray and weather resistance.
Epoxy/epoxy polyester hybrid type (indoor version): Good adhesion, strong anti-corrosion performance, only suitable for indoor environments, not exposed to direct sunlight.
2、 Main application industry scenarios
1. Building materials (most commonly used outdoors, pure polyester bonding powder)
Aluminum profiles, doors and windows, curtain wall aluminum panels, guardrails, outdoor lighting fixtures shells; Aluminum alloy doors and windows with champagne color and sparkling silver metallic effect mostly use bonded metal powder.
2. Home appliances and hardware (indoor)
Air conditioner casing, refrigerator, washing machine, kitchen and bathroom hardware, metal furniture, office equipment casing, with a metallic shimmer silver and matte metallic texture appearance.
3. Transportation auto parts
Automotive wheels, automotive parts, motorcycle accessories; Some wheels and chassis decorative parts use bonded metal powder, which balances appearance and anti-corrosion and wear-resistant properties.
4. General industrial, 3C shell
Communication equipment casing, chassis cabinets, fitness equipment, new energy equipment accessories; Workpieces that require metallic texture and batch electrostatic spraying.
Attention: Binding only solves the problem of metal pigment adhesion during construction and does not change the properties of the resin itself.
Pure polyester bonding powder must be selected for outdoor use; Epoxy system bonding metal powder can only be used indoors, and it will quickly powder and fade outdoors.
