Detail

product description

This series of products uses polyester resins, curing agents, additives and pigments provided by internationally renowned brands, which have excellent weather resistance, chemical resistance and mechanical properties. Can provide a variety of colors and gloss, or customized according to customer specific requirements.

Powder properties:

Chemical type: polyester resin, curing agent

Liquidity: 120-140

Particle size: suitable for high voltage static or friction gun spraying

Specific gravity: 1.3-1.7g/cm³ (depending on the color)

Powder type: conventional flat powder, hammer pattern, sand pattern, metal-containing pigment, pearlescent pigment, special effect, thermal transfer type, etc.

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.

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.
