epoxy-polyester powder coating is an epoxy-polyester-based thermosetting powder coating, formulated to offer a good flowing out. It is suitable for indoor use as decorative and protective coating.

Advantages:

• Good chemical resistance
• Excellent chemical property
• Excellent flexibility
• Recommend for interior

Application Areas:

• Home domestic appliance such as microwave ovens, refrigerators
• Home and office metal furniture, safety box, filing cabinet
• Instruments and apparatus
• Traffic vehicles
• Medium industrial electrical trunkings, shelvings, light fixtures, machinery ect.
• Light fixtures, ceiling panels and switch boards.

Application Schedule:

• Applied by electrostatic spraying gun that can provide negative tension of 60-80kV
• Curing Schedule: 180°C 15minutes
• Optimal film thickness: 60-90μm

Powder Properties

• Specific gravity:1.25-1.75(depend on colors)
• Particle size distribution(Laser Particle size analyser): Less than 5% above 100μm;50-65% above 32μm
• Average particle size:35-45μm

Average Coverage

• 8-12 square meters/kg, thickness 60μm(100% of the powder coating utilization rate)

Gloss&Texture&Color

• Supper Matt(<10%), Matt(<20%),Sub-gloss(20%-50%),Semi-gloss(50-75%),Glossy(76%-85%),High gloss(>85%)
• Wrinkle/Sanded/Netted/Crackle/Crocodile/Hammer/Woodgrain/Metallic/Pearl/Antique
• RAL color, full color range is available

Substrates and Pre-treatment

In order to obtain optimal anti-corrosion properties it is recommended to apply a chemical pretreatment prior to powder coating application

• Ferrous metals(cold rolled steel, cast iron ect.):Iron or Zinc phosphation
• Zinc surfaces(Galvanized steel, zinc alloy):Chromation or Zinc phophation
• Aluminum alloys:Chromatation

Storage

• Should be stored under dry conditions with good ventilation at a temperature not exceeding 30°C
• Storage period recommended should not exceed 6 months, in case exceeding 6 months without affecting their free flowing properties, the powder will still have optimal characteristics.
• Should be protected from excessive heat, humidity, water and contamination with foreign materials such as powder, dust, dirt ect.
• Any leftover powder should be kept in an appropriate area that is cool and dry. Do not expose to the air too long as the powder properties may deteriorate with the moisture.
