Plasma is the fourth state of matter and is formed by the applying voltage difference between two electrodes and can be either hot or cold. Plasma technology, along with nanotechnology, has been able to solve many problems in various industrial fields, including paint and coating. One of the problems in the paint industry is the adhesion of paint to the surface. For this purpose, the substrate needs to be prepared before coating or painting, so that the paint can adhere better to the surface. The primary purpose of any preparation process is to eliminate surface contamination and to establish close contact between the two surfaces on a molecular scale. Plasma is able to change the hydrophilicity and coloring of the surfaces by altering the physical and chemical properties of the surfaces. Plasma technology is widely used in the various industries to solve adhesion, sealing and cleaning problems. Applying plasma results in nanometer roughness on the surface, thereby increasing surface energy and activation. Plasma electrodes help to process plastic parts more quickly, resulting in a reduced processing cycle time, depending on the material and formula of the polymeric parts from 2 to 120 seconds. This technology has useful applications and has been developed in various industries such as automotive, electronics, medical, textile and home appliances. The most useful applications of plasma are in surface modification. PIA Co. is working on designing and manufacturing surface plasma processing equipment such as Corona Triment and Plasma Glide to process surfaces of a wide range of materials to improve surface properties such as paint adhesion. Thanks to its resources, experience and high level of technical knowledge, the company is able to provide the best surface processing systems to meet any challenge.
