Automobile heel hub Powder Coatings

Brief introduction:

We specially design powder coatings for wheel hub, to meet the requirements of primer protection and surface glossing. We have developed series of products to meet different requirements. The powder coatings bring your products with good leveling, strong adhesion, anti fog or salt corrosion, being used in many famous wheel hub factories.

Properties of products:

•Good leveling

•Strong adhesion

•Strong anti-corrosion of fog and salt

Series:

1 transparent powder coatings:

•Super pure polyester transparency

•Standard pure polyester transparency

•Common pure polyester transparency

2 Primer coatings:

•Pure polyester primer powders

•Super leveling epoxy-polyester mixed primer powders

•Low gloss and super leveling epoxy-polyester mixed primer powders

Physical properties of powder coatings:

• Gravity: 1.2-1.7-g/cm3 (up to formulas and colors)

•Grit size distribution: 35-40μm, 10%<10μm, 0.5%>100μm

Properties coating layer:

All the parameters below are gained from test of oil-free, rust removal cold rolling steel board of thickness of 0.8mm, under experimental circumstances, with coating layer thickness of50-870μm;

Package:

Carton package, with double PVC liner bags, 20kg/carton

Storage:

To be stored under 40 in dry and ventilated warehouse, avoiding straight sunlight. If stored at air-conditioned warehouse, the powder coatings should be put in the spraying machine room for some time before spraying, to let their temperatures to be same as that of machines. Avoiding damp caused. Under this storage conditions, the powder coatings can be qualified for 12 months. If they are expired, user can check and test, the powder coatings can still be used if meeting relevant requirements.

Hygiene and security

Powder coatings do not contain any poisonous substances, and there is no poisonous gas coming out during spraying and oven heating.  Workers should wear masks, avoiding intake of powder coatings. Trying reduce the contact between skin and powder coatings for long time. The powder coatings attached on skin can be washed away by soap.
