Powder Coating Procedures
Powder Coating procedures for external and internal structural components.
Inspect the product for flaws or defects, repair as needed
Sandblasting product (galvanized or bare steel) 0.75 - 1.5 mil. Profile compatible with SSPC-SP-10 (NACE 2 - near white metal scraper) for bare steel, SSPC-SP-7 (NACE 4 - Brushing scraper) for galvanized steel.
Preheat the oven to 450 ° F.
Mask teeth, machined surfaces and anything else that's needed.
Clean the product with compressed air.
Put the product in the oven for pre-cooking.
Pre-cook the product at 450 F. Verify product temperature is 375 F on the entire product before applying primer.
Take the product out of the oven and apply 2.5 - 3.5 mil. Zinc rich epoxy primer in powder base produces specifications on hot product so it melts on contact.
Allow the product to cool between 125 ° F and 175 ° F
Apply 2.5 - 3.5 mil. It produces top coat according to powder production properties.
Place the product in the oven at 425 ° - 435 ° F until the entire substrate falls within the curing window indicated by the powder manufacturer.
Remove from oven to cool, check, de-mask and drain.
Wrap and pack the product.
All procedures and work will be done in-house in a controlled environment. This will protect against any external contamination. (Sudden corrosion caused by transportation and weather conditions, road pollutants, etc.).
