Epoxy Polyester Powder Coating
General Introduction:
Epoxy resin and polyester resin are used as the main raw materials, and have their own unique properties, so that the produced film has excellent decorative, mechanical properties and strong corrosion resistance, widely used in the coating of various indoor metal products.
Scope of application: Decoration and coating on the metal surface of household appliances, metal furniture, office facilities, electromechanical equipment, interior decoration materials, automobile accessories, children's toys, etc.
Product Series:
Standard type and low temperature solidified powder coating
It can be made into products with high light (80% above), semi-light (50-80%), flat light (20-50%) and non-light (less than 20%). According to the user's requirements to control the gloss.
Physical Properties:
Specific gravity(g/cm3, 25℃): 1.4-1.7
Particle size distribution: 100 % less than 100 micron (It can be adjusted according to the special requirements of coating)
Construction Conditions:
Pretreatment: Different pretreatments are used for different substrates (phosphating treatment, sandblasting treatment, shot peening treatment, please contact us for more detailed information)
Curing mode: it can be cured by electric infrared, gas infrared, heat convection drying path, oven and other ways
Curing Conditions:
Standard 180℃(workpiece temperature), 15 min
Low temperature fixed type 160℃(workpiece temperature), 15 min

Notes:
1.The above tests used 0.8mm thick cold-rolled steel plates with a coating thickness of 30-40 microns after standard pretreatment.
2.The performance index of the above coating may decrease slightly with the decrease of gloss.
Average coverage:
9-14 sq.m./kg; film thickness 60 microns (calculated with 100% powder coating utilization rate)
Packing and transportation:
cartons are lined with polyethylene bags, net weight is 20kg; Non-hazardous materials can be transported in various ways, but only to avoid direct sunlight, moisture and heat, and avoid contact with chemical substances.
Storage requirements: Clean, dry, ventilated, away from light, room temperature below 30℃, and should be insulated from fire source, away from heat source.
Notes:
All powders are irritating to the respiratory system, so avoid inhaling powder and steam from curing. Try to avoid direct contact between skin and powder coating. Wash skin with water and soap when contact is necessary. If eye contact occurs, wash skin immediately with clean water and seek medical attention immediately. Dust layer and powder particle deposition should be avoided on the surface and dead corner. Tiny organic particles will ignite and cause explosion under static electricity. All equipment should be grounded, and construction personnel should wear anti-static shoes to keep the ground to prevent static electricity.
