Decorative & Functional Coatings
Powder coat can be either functional or decorative in emphasis. The majority of modern powder coats are classified as decorative finishes, formulated to maximize color, gloss, and texture. Powder coats formulated for maximum corrosion resistance, as might be required for outdoor applications in the marine and architectural industries, are classified as functional finishes.
Some powder coats are excellent corrosion barrier coatings, and some are not. Powder coats classified as decorative finishes, while smooth and glossy to the naked eye, can be porous on a microscopic scale and not the best corrosion barrier coating. In outdoor applications requiring a decorative finish, excellent corrosion resistance can be achieved by using a two-coat primer/top-coat finish, or even a three coat primer/top-coat/clear-coat finish. The ultimate in corrosion barrier coatings are powder coats classified as functional finishes, as they do not have the porosity inherent in decorative finishes.
