but you will need to remove the previous powder-coated surface first before you can apply a new coating color with the powder coating process. This process can be daunting and complicated to do.
Some of the most complicated issues in the field of powder coating and means to rectify them are discussed. Most electrostatically sprayed powder coatings are given a negative charge out of the powder gun, while the part itself is grounded. poor ground affects the transfer efficiency and results...

Our blog post above takes you through the steps of how to wash and how to re-waterproof your GORE-TEX jacket. Can I use either powder or liquid detergent? For best results, a mild liquid detergent is recommended. How much laundry detergent do I use? Depending on your local water ...
Coating powders generally diminish in thickness during the curing process so these procedures require a reduction factor be determined to predict cured film thickness. Ultrasonic instruments also measure uncured powder, but do so without touching the surface. Instead of measuring powder height, they ...
Powder coating is different from conventional liquid paint, because it needs no solvent to prevent binders and fillers from solidifying. Applied electrostatically, powder coatings form a painted skin much thicker than ordinary liquid paints. Powder coating also tends to dry flawlessly and produces much...
Powder coating is a process by which electrostatically charged powder is applied onto an earthed object.
