Epoxy Powder Coating

DESCRIPTION:

• Epoxy powder coating is a series of epoxy based powder coating designed to give optimum mechanical properties and exceptional protective qualities on components and fabrications where long term exposure to ultra violet light or exterior weathering is not anticipated.

• This series are available in a wide range of colors with different gloss and texture.

MAIN PROPERTIES:

• Excellent corrosion protection;

• Excellent  chemical resistance;

• High mechanical performance ;

• Suitable for interior use.

Remark

1,   The above test use cold-rolled steel(thichness:0.8mm) to remove rust,oil.  Film thickness: 50-70um.

2,   All the indicators of film features will be down lightly depending on reducing of luster.
