Controlled film thickness - A controlled more uniform and, if required, a higher film thickness can be obtained with powders than with conventional paint systems in one application. Improvements in the appearance of thin films has also made this a viable option for certain applications.
Wide range of coatings available - A broad variety of decorative and functional coatings are achievable using powder. These range from matt to high gloss, smooth to textured finish and include metallic and other speciality effects. Choice of polymer type can optimise properties such as corrosion resistance and exterior durability.
Non-metallic surfaces can be coated - Surfaces such as glass and certain thermosetting mouldings which can withstand the stoving temperatures involved can be powder coated. The scope of materials which can be used is ever-increasing as advancements in lower bake technologies are made.
Superior film properties - With solvent based systems, the solvent balance must be carefully adjusted to the polymeric type, application and curing conditions, as many film defects can be traced directly to incorrect solvent balance. With powders no such condition exists and in general superior film properties such as adhesion and corrosion resistance are obtained with powders compared to polymers deposited from liquid systems.
