Powder coat colors and types of powders
Did you know that there are thousands of colors and many textures and special powders?
Reds, blues, oranges, blacks, whites, metallic, veins, hammered, river, speckled and the list goes on and on.
Let’s break down the types of powder coat varieties.
Epoxy powder coat is very hard when cured and is resistant to many chemicals. It’s a great coating for inside applications as it is not UV stable.
Polyester Urethanes stand up to UV light very well and provide a show quality finish while being durable.
Hybrids cure hard like epoxy powder coat but is easier to coat metal parts. Basically it gives you the characteristics of a epoxy with the spraying ease of a urethane.
Polyesters come in TGIC and TGIC-Free formulas. Polyester powder coats provide excellent exterior protection against weathering and UV exposure. Polyesters apply to metal substrates well and have great overbake capabilities.
Powder coat primers add durability to the overall coating. A gas-out primer can help prevent imperfections in the topcoat by slowing down the cure rate. Zinc rich primers add weathering protection. The zinc is sacrificial in that it is “attacked” by elements before the metal substrate is “attacked”.
Clear coats help protect against scratches and UV damage. The three main types of clear coats are; full gloss, semi gloss, and low gloss.
RAL colors are standardized and come in both powder and liquid paint.
