Infrared Drying

Definition

Infrared drying is a process that utilizes infrared radiation to rapidly evaporate moisture from a material's surface. This method is particularly efficient for painting and coating applications, as it allows for quick drying times while ensuring an even finish and reducing the risk of defects. By applying targeted heat directly to the material, infrared drying can enhance adhesion and improve the overall quality of coatings and paints.
