Operational Points

Adhere to the following points for the best powder coating results:

•The workpiece MUST be clean of debris, paint, or other non-metal material. Depending upon the application, cleaning may be as simple as using mineral spirits and clean rags, or it may require a much more compli- cated "pre-treament" process, such as sand- blasting.

•obtaining good powder coating results depends on many variables—workpiece pre- treatment, powder chemical composition, method of spraying, curing procedure, etc. Read books, use online resources, or talk to professionals to gain an understanding what is required for your operation.

•use only high-quality powder coatings. Investigate the many powder options on the market and choose the one that best suits your application.

•Use only pressurized air that is clean, dry, and free from oil.

•Make sure the system ground clip is firmly secured to the workpiece or hanger with good metal-to-metal contact.

•To begin spraying, depress the foot switch and spray gun trigger simultaneously. The foot switch enables power to the gun conduc- tor pole, which electrically charges the dust as it leaves the gun. The spray gun trigger allows air to flow through the powder cup and gun to send the powder onto the workpiece.

•Use the air pressure regulating valve and powder flow regulating screw to control the flow of powder through the spray gun.

•Experiment with the scatter tips to gain an understanding of the effects attained with each tip.

•Use a side-to-side overlapping pattern when spraying. Most powder products require a coating of approximately 2mm. Check the powder manufacturer's specifications and practice attaining the correct thickness on a scrap workpiece.

•You MUST “cure” the workpiece to complete the powder coating process. The curing oven must have good ventilation. Poor air circula- tion can cause discoloration or hazing.

Fumes from the curing process are poison- ous! Make sure the curing oven is well-ven- tilated. Use a dedicated electric oven that will NOT be used for cooking food.

•Follow closely the powder manufacturer's directions for curing. Under-curing can result in poor physical qualities and over-curing can change the color.

•Always maintain clean powder cups, spray gun, and work area. Contamination of pow- der products by debris or other powder mate- rial can produce unexpected results.

•Some orange peel effect may be unavoid- able. If this happens, wet-sand the workpiece with 400 grit sandpaper, thoroughly dry the workpiece, and repeat the coating process.

•to remove slight imperfections, buff the workpiece with a loose buffing wheel and white rouge compound.

Exposure to powder coat- ing materials can cause eye, lung, or skin injury. Always wear ANSI-approved gog- gles, NIOSH-approved res- pirator, and wear clothing that will protect your skin.
