Special-effect powder coatings, texture, veined, hammertone and metallic finishes have been produced more than 20 years ago. The dry blending process combine two or more products in powder form the objective of obtaining a homogeneous mixture when metallic flake or mica is included in a dry blend mixture.
In the bonded metallic powder process, the aluminum or mica flake is bonded to the base powder through heat and impact.
In a dry blend powder, the aluminum flake can be separate from the base powder and behave almost like a grain dust. If there are static charge or any type of ignition source, booth can actually catch on fire. Some people do not realize the difference between the two type of metallic powder until they have extremely high rejects or enormous application problem.
What is Metallic Bonding Process?
- After mix base powders and metallic pigments,
- Physically bonding with special process
Advantages of Bonded Metallic Powder?
- By using of reclaimed powder, you can save coating cost
- Uniform metallic effect
- Powder is not accumulated to Gun a diffuser.
- High content of metallic powder than
Properties of Bonded Metallic Powder.
- There is no metal Powder separation.
- Can use for reclaimed Powder.
- Higher Metallic Effect.
- More expensive than Dry Blending Metallic Powder

*Obciously, safety is a concern, but people use bonded materials mainly to achieve color consistency, reduce rejects and produce a high-end finish without any streaks.
Application of metallic powder
Base
Bonded metallic series are based on hybrid polyester, polyurethane resin system. Boned metallic product is made by particular manufacturing process that mixing process applied usually is not. It improves a coating workability remarkably for metal, and base powders are boned together. Boned powders can increase more a metallic content & has a marked improvement in metallic effects
Field of application
Bonded metallic series are recommended for aluminum alloy wheel, home appliances(microwave oven, refrigerator, washing machine etc., out side cabinet), steel furnitures, lighting fixtures, computer case etc.
If do you use Bonded Metallic Powder
By using of reclaimed powder, you can save coating cost. Uniform metallic effect, Powder is not accumulated to Gun a diffuser. Higher content of metallic powder than Blending type, therefore can raise more metallic effect.
If do you select Bonded Metallic Powder
Can enhance value of goods by rich metallic effect. Can reduce production costs by coating line inferior rate decrease. Coating expense becomes low relatively, therefore can improve price competitive power of finished product. Apt to diversify color design
