High Temperature Resistant Powder Coating
General Introduction:
High temperature resistant powder coatings is made of special high temperature resistant powder coating resins and combination of high temperature resistant fillers, special functional powder coating has good high temperature resistance, corrosion resistance, and color stability, and applied to all kinds of motor vehicle exhaust pipe, oven, electric rice cooker, both inside and outside wall, home kitchen burning gas, the fire point, the heating plate, heat exchanger, lighting lamps and lanterns, exhaust pipes, grill artifacts of coating
Product Series:
to provide heat resistance of 230℃X6 hours, 250℃X3 hours, 300℃X2 hours.
Physical Properties:
Specific gravity(g/cm3, 25℃): 1.4-1.6
Particle size distribution: 100 % less than 100 micron. (It can be adjusted according to the special requirements of coating)
Construction Conditions:
Pretreatment: the surface should be thoroughly cleaned to remove oil and rust. The application of iron series phosphating or higher standard zinc series phosphating can further improve the corrosion protection ability.
Curing mode: manual or automatic static gun construction
Curing conditions: 230 ° c (workpiece temperature), 15 minutes (130 ° c x5mim, the water in the powder shall be slowly volatilized to help the coating fully level off, and then rise to 230 ° c and 30mim (workpiece solid temperature to help the coating fully solidify)

Notes:
1.The above tests used 0.8mm thick cold-rolled steel plates with a coating thickness of 60-80 microns.
2.The performance index of the above coating may change with the change of color and gloss.
Average coverage:
9-12 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:
Store in a ventilated, dry and clean room at 30℃, not close to the fire source, central heating and avoid direct sunlight. It is strictly prohibited to pile up in the open. Under this condition, the powder can be stored for 6 months. After the storage life can be re-examined, if the results meet the requirements, can still be used. All containers must be repackaged and repackaged after use.
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.
