In the informative article “Powder Coatings vs Energy-Cure Coatings” from PFOnline, the distinctions between powder coatings and energy-cure coatings are elucidated, providing valuable insights into their applicability and benefits.
A query regarding the suitability of 100% solids coatings prompts an exploration of two prevalent types: powder coatings and energy-cure coatings. Powder coatings, known for their durability and low VOC emissions, consist of powdered material without solvents. Conversely, energy-cure coatings, often termed UV or electron beam coatings, begin as liquid but cure without solvent evaporation, also emitting minimal VOCs.
Powder coating, invented in the early 1940s, involves spraying the powder onto the part and melting it using electrostatics. While effective for metals, it may pose challenges with non-conductive substrates, requiring special considerations. Additionally, powder coating films are typically thicker than solvent-borne coatings.
Energy-cure coatings offer an alternative approach, curing rapidly under UV or electron beam radiation. Although they start as liquid, they cure into a solid film without solvent evaporation, offering similar environmental benefits as powder coatings.
