Corrosion Resistance

Powder coatings act as a barrier to corrosive chemicals and moisture, which are essential components of the corrosion process. Zinc-rich types, which provide a sacrificial metal, produce longer life and are often used as primer coats when severe conditions demand an extra measure of protection.

Chemical Resistance

Chemicals are not limited to chemical manufacturing plants. They can be cleaners used around the home and office; lubricating oils, gasoline and anti freeze used in the garage as well as many other compounds which may come in contact with a coating during a manufacturing process or in subsequent end use. All should be identified during the coating selection process to insure adequate protection.

Electrical Insulation Resistance

Most powder coatings are excellent electrical insulators. Some, however, are specifically designed and tested for use on electrical components. It is important to define the dielectric strength required as well as any other related electrical property. Frequently trade groups or organizations such as Underwriters Laboratories spell these out as “standards”.

Heat Resistance

Coatings are frequently subjected to elevated temperatures for constant or intermittent periods while in use. Higher temperatures generally cause some degradation, which may reduce the useful life of the coating. Despite this fact, successful powders have been developed for barbecue grills and cookware, under the hood automotive and many other high temperature environments.

Abrasion Resistance

Powder coatings generally provide outstanding abrasion resistance. Store and library shelving, home and office furniture are just a few of the markets where powder's superior abrasion resistance has been recognized.

Impact Resistance

Like abrasion resistance and hardness, impact resistance is a measure of the coating's toughness. Powder coatings are formulated to withstand blows from hammers and wrenches on an oil rig, stone damage to lawn mowers and automotive components as well as the everyday wear and tear of children's toys, furniture and playground equipment.
