polyester powder coating
This series of products is based on polyester resin and is used for ordinary powder coatings indoors and outdoors.Available in a variety of colors, patterns and gloss. Can also be designed and manufactured according to customer requirements. Suitable for outdoor products such as home appliances, highway guardrails, general industry, automotive parts, outdoor furniture and construction machinery
Chemical type: polyester resin type
Specific gravity: 1.3-17g/CM3
Type: conventional flat powder, hammer pattern, sand pattern, containing metallic pigment, containing pearlescent pigment, special effect, thermal transfer type, etc.
Pretreatment
1 zinc phosphating (minimum 6μm)
2 iron phosphating (minimum 6μm)

Note: 1. The above experiment uses a 0.5 mm rust-removing and degreasing cold-rolled steel plate with a thickness of 60-80 μm.
2, the performance index of the above coating film may change with the change of color and gloss
Health and safety
This powder coating is a non-toxic product, but should avoid inhaling dust during use. It is recommended that operators wear appropriate dust masks and eyes. If possible, avoid long-term direct contact between skin and powder coatings.
Storage requirements
Store in a 28° C， Celsius, ventilated, dry, clean room in hell. Keep away from fire, heating, and direct sunlight. Do not stack in the open air. Under these conditions, the powder can be stored stably for 12 months. If it exceeds the storage period, it can be re-inspected. If the test results meet the requirements, they can still be used.
