    Detailed

    [epoxy / polyester powder coating series]
    Sketch
    It is made of polyester resin and epoxy resin as main base material. It has excellent decoration, mechanical properties and good corrosion resistance of epoxy and polyester.
    Characteristic
    With good tightness, impact resistance and other mechanical properties are good. Good leveling and gloss. Strong resistance to chemicals and corrosion resistance. Superior to pure epoxy powder for heat resistance and smooth light stability.
    purpose
    Widely used, such as: furniture, household appliances, industrial equipment, sports equipment, toys, hardware machinery, shop shelves, lamps and other indoor use.
    Product line
    1, can provide standard curing type and low temperature curing products;
    2, can be made into a variety of gloss and colorful color: G series of high light (greater than 80%), B series of semi light (80 - 20%), W series of light (less than 20%) products. The specific gloss color is specified by the user;
    3, can be made of sand grain, wrinkles, crazing, hammer, moire, crack, imitation stone, metal effect, transparent, antique and other art texture type products.
    Application condition
    Epoxy / polyester powder coating is suitable for coating equipment: high voltage electrostatic spraying, electrostatic fluidized bed and fluidized bed, can provide products for friction coating.

    Remarks
    The properties of the above coating may decrease slightly with the decrease of gloss and texture.
    Product packaging
    Packed in cartons lined with poly vinyl chloride plastic bags, net weight 25kg or 20kg per carton.
    Storage condition
    Storage at 35 degrees below, dry, ventilated, clean room, shall not be near the fire, heating, while avoiding direct sunlight, is strictly prohibited open-air stacking. Under this condition, the powder can be stored for 12 months, extended and renewed for verification. If the result meets the requirements, it can still be used. (Note: for fast curing and gloss less than 40% powder, storage temperature is lower than 30 degrees is appropriate; all types of powder because of its low storage temperature and storage period extended
    Health and safety
    The powder coating does not contain toxic substances, baking power and no toxic gases produced by environmentally friendly products, but should avoid inhaling dust during use, the operator should wear anti-dust masks, glasses, and minimize the long-term contact with the skin and powder coating, coating adhesion to the skin, can be washed with soap.
