Hybrid powder coating
This series of products is based on epoxy resin and polyester resin. It has good light resistance and heat resistance compared with epoxy powder. It can be supplied in various colors, patterns, gloss or customized according to customer requirements. Products are widely used in home appliances, furniture, electrical appliances, indoor products and industrial parts.
Powder characteristics:
Chemical type: epoxy / polyester
Specific gravity: 1.3-1.7g/CM3
Particle size: suitable for high voltage static or friction gun spraying
Pretreatment
Appropriate pretreatment methods based on different substrate and coating quality requirements
1 zinc phosphating (minimum 6μm)
2 iron phosphating (minimum 6μm)
3 The working surface should be treated with derusting, degreasing, phosphating, etc., and the workpiece without surface chemical treatment is poor in corrosion resistance and other related performance is poor.
Application condition
Spray gun: electrostatic or friction spray gun
Thickness: average 60-80μm
Corona gun voltage: 60-80kv
Curing conditions: 200 ° C × 10 min (MT) / 180 ° C * 20 min (MT)

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.
