Epoxy-polyester (Hybrid) coatings are prevalent coatings with little exposure to sunshine. Of all the powders that are now available, they have the best chemical and corrosion resistance and give exceptional hardness. This sort of powder’s simplicity of usage and large variety of cure schedules are further benefits. Epoxies stick to metals incredibly effectively; pre-treatments for the metal, such as phosphate and sandblasting, enhance adherence
Epoxy-polyester (Hybrid) powders have the disadvantage of having poor UV protection. They may fade and chalk in the sun and after a few months, they frequently start to disintegrate on the surface. Epoxies are better suitable for indoor applications as a result. As a final point regarding epoxies, many primers are epoxies because of their strength in adhesion and resistance to corrosion. They should be used as a pre-coat under another powder coating type because they don’t withstand weathering conditions effectively, allowing you to take use of their advantages while masking their shortcomings.
