While some powder coatings have provided what is commercially known as a “reflective” surface, this usually has meant simply a high gloss level. This type of reflection, where light is “scattered” or diffused, is not retro-reflection. A new powder coating process can enhance corrosion protection and nighttime safety by achieving true retro-reflectivity.
Recently, North Coast Polymers in Port Clinton, OH, has created and patented a process using retro-reflective elements and a new formulation of powders to create a retro-reflective surface with powder coatings. Using this cost-effective process, all surfaces that can be powder coated - including metals, plastics, wood and glass - can be made to reflect light at night, thereby improving safety.
