What are the Advantages of Powder Coatings?

Post Time:2014-08-13

• Powder is ready to use
You can use the powders immediately. There’s no need to mix them with anything else, like solvents or catalysts. Great news if you’re looking to save time on the shop floor.

• Powder means no solvent wastage – simply more environmentally friendly
There is no costly wastage of solvents which, at application viscosity, constitutes up to 70% of conventional liquid paints. These solvents, which volatilize during application and stoving are usually not recoverable. Legislation introduced in various parts of the world has prohibited their discharge into the atmosphere which means in some cases afterburners have to be installed to eliminate the solvents with an attendant increase in costs.

• Powder helps reduce air pollution
Any over sprayed powder is recoverable (great news in reducing waste), and no powder needs escape into the atmosphere.

• 95% powder utilization
With powder, material loss can be kept to less than 5%. Any powder overspray can be recovered, and the recovered powder can be blended with virgin powder to provide up to 95% utilization.

• Powder helps reduce the health hazard to operators
As powders do not contain solvent, there is a marked reduction in nose, mouth and throat irritation. With liquid coating, any liquid paint which comes into contact with an operator’s skin needs to be washed off with solvent, and then removed by emulsifying with soap in hot water. Sometimes special industrial hand cleaners even have to be used. In general powder does not cause skin irritation though in rare cases individuals may react to certain types of powder. The powder can be removed from the skin easily by washing with warm water.

• Powder offers 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.

• Durability
Powder coating is a high-quality finish found on thousands of products you come in contact with each day. It provides a more durable finish than liquid paints can offer, while still providing an attractive finish. Powder coated products are more resistant to diminished coating quality as a result of impact, moisture, chemicals, ultraviolet light, and other extreme weather conditions. In turn, this reduces the risk of scratches, chipping, abrasions, corrosion, fading, and other wear issues.

• With powder, a huge range of coatings and effects are available
Whether it’s decorative, functional or both, powder coatings offer a viable solution. An enormous color range, matt, satin, gloss, metallics, textures, soft touch – you name it. And the functional properties range from anti-bacterial to anti-corrosion and everything in between.
