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 ultraviolet light or exterior weathering is not anticipated. It is mainly used for metalwork that requires excellent corrosion resistance, good electric insulation and flexibility. Outdoor use is not suggested.
Features
Specific gravity: 1.4-1.7g/cm3
Particle-size distribution: 100% below 100μm (adjustable)
Utilization rate: 4-11㎡/kg (film thickness = 60μm)
Application: Applied by manual or automatic electrostatic spray equipment. Unused powder can be reclaimed using suitable equipment and recycled through the coating system.
Curing condition: 180℃x15mins (type A) / 140℃x20mins (type B)
Colors: Available in gloss, satin, matt or textured finishes in a wide range of standard colors, or can be custom matched to the user’s requirements.
