FAQ's of Epoxy-Polyester Thermosetting Electrostatic Spray Powder Coating:

Q: How do you apply the Epoxy-Polyester Thermosetting Electrostatic Spray Powder Coating?

A: The powder coating is applied with an electrostatic spray gun. Metal surfaces should be properly cleaned and prepared before spraying. Once applied, the coated items must be cured in an oven at 180C-200C for 10-15 minutes for optimal performance.

Q: What are the available finish and color options for this powder coating?

A: You can choose from glossy, matte, or semi-gloss finishes, with a wide range of customizable colors such as yellow, orange, red, blue, teal, grey, white, and more to match specific design requirements.

Q: What benefits does this powder coating offer over traditional paint?

A: Compared to liquid paints, this coating provides superior adhesion, enhanced resistance to impact and corrosion, longer-lasting color retention, and increased durability. It is also environmentally friendly, being RoHS compliant and non-toxic.

Q: Where can this thermosetting powder coating be used?

A: It is suited for use on metal surfaces in various industries, including appliances, furniture, architectural applications, and automobiles, wherever a robust and decorative finish is required.

Q: What is the expected coverage of the powder coating per kilogram?

A: Each kilogram of powder can cover approximately 8 to 10 square meters at a 60-micron film thickness, depending on application technique and surface type.

Q: How should the powder coating be stored for maximum shelf life?

A: Store the coating in a cool, dry location below 25C, away from direct sunlight, in its original, sealed packaging. This ensures a shelf life of up to 12 months (if unopened).
