1. General introduction:
Powder coatings are mixed with a certain proportion of the resin,
fillers, curing agents and other additives, then prepared by hot
extrusion, crushed and sieved. The products are stable at room
temperature storage, then baking heat melted and solidified to form
a smooth and bright permanent coating to achieve the purpose of
decoration and corrosion.
2. Features:
1). The products are non-toxic, solvent-free and non-toxic volatile
substances, there are no intoxication, no fire, no "three wastes"
emissions and other pollution problems, in full compliance with
national environmental laws.
2). Raw material utilization is high, the highest utilization rate
even more than 99%.
3). After being pre-coated handle, disposable construction, without
primer, you can get a sufficient thickness of the coating, easy to
automate operation, high production efficiency, reduce costs.
4). Dense coating adhesion, good impact strength and toughness,
high
coverage corners, with excellent resistance to chemical corrosion
and electrical insulation properties.
5). Powder coatings storage and transport are safety and
convenience.
3. Product series:
The products include high light (above 86%), glazed (76%-85%),
matte (20%-50%), low light (below 20%). We also offer a variety of
shiny products according to the needs of users.
4. Powder physical properties:
Proportion: 1.2-1.8 (depending on the color and gloss).
Particle size distribution: 100% less than 125 microns (more than
85% between 60 to 90).
Liquidity (180°C): 22-35mm.
Curing conditions: 200°C, 10 minutes.
5. Average coverage:
8-10m³/kg, the membrane is 60μm (calculate by 100% utilization rate
of powder coating).
6. Packing:
Carton package, lined with double polyethylene bag, net weight
20kg.
7. Storage requirements:
Store below 30°C, ventilated, dry, clean room, not near the fire,
heat, direct sunlight, open dumps is prohibited.
