RAL1003 signal yellow electrostatic thermoset powder coating better thin to thick wall capability
Polyester and acrylic powder coatings are mainly used for coatings. Acrylic powder coatings are used to enhance the flow and leveling as well as chemical resistance and enhanced stain in polyester hybrid coatings. Hybrid thermosetting powder coatings are used in the manufacture of industrial components to achieve overall enhanced performance as they offer advantages of two or more powder coating at the same time.
In addition, environmental regulations are expected to further fuel the thermosetting powder coatings market. Unlike liquid coatings, powder coatings do not need solvents in the application process; hence they are environment-friendly. Environment related agencies such as Environmental Protection Agency (EPA) and Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) promote use of powder coatings instead of liquid coatings to reduce environmental hazards.
FLUOROPOLYMER resins are top of line for exterior weatherability and UV stability in both powder and liquid coatings. Fluoropolymer powder coatings are purposely tailored for the architectural market and offer a long-life durable finish. Fluoropolymer powder coat resin systems can be formulated to meet the requirements of the high performance AAMA 2605 specification.
