RAL2012 Salmon orange electrostatic thermoset powder coating for Computer bodies
Polyester powder coatings. Polyester resins are, for the most part, the workhorses of the North American powder coatings market. More than 60 percent of the market uses polyester-based powder coatings, which hold up very well to standard outdoor exposure. Polyesters give the coater a broad application field, but let’s not confuse this with oceanfront exposures in one coat or elevated levels of weatherability.
Polyester TGIC (triglycidyl isocyanurate). If we look at chemistry, the primary choice is still polyester TGIC, although polyester TGIC-free powder coatings are gaining ground more and more. Polyester TGIC is a very robust powder system with a huge spectrum of application possibilities and effects.
Polyester TGIC-free. These powder coatings are the primary chemistry that has been in use for more than 15 years in Europe. They have some distinct advantages and disadvantages. Advantages include easy application with high first-pass transfer efficiency, excellent storage stability, very smooth surface and low-temperature-cure applications. Disadvantages include film thickness limitations because of the small percentage of water that needs to evaporate during cure. This is part of the chemical reaction occurring and, with smart formulation, a lot of this can be counteracted. It tends to appear in applications requiring very heavy film builds.

rowing demand from automotive industry is expected to drive the thermosetting powder coatings market. Automotive components including interior and external metal parts require coatings to protect them from weathering conditions. Polyesters are major type of powder coatings used in the automotive due to their better outdoor weathering properties. Epoxies are used as functional coatings for interiors where adhesion, impact resistance and corrosion resistance is necessary.
