Utility of plasma treatment for pre-treatment of surfaces
Often plasma treatment is used for treating surfaces of various materials prior to any coating, printing or adhesion. On industrial front, plasma treatment is considered as a pre-treatment of surfaces that helps removing contaminants existing on surface. Plastics being homopolar, do not bond easily. Any printing or coating on plastic surface loses its sheen due to glossy texture unless pre-treated with plasma treatment. Similarly, materials like ceramics and glass can also be pretreated with plasma before any gluing, printing or lacquering.
Plasma treatment technology has introduced innovative solutions to problem of adhesion of ink, glues and coatings on different surfaces faced by many industries. Plasma treatment improves wet ability i.e. tendency of one fluid to spread on or adhere to other solid surface in the presence of other immiscible fluids.
