Plasma treatment creates the ideal surface cleanliness conditions for adhesive bonding to be consistently strong and reliable. Using plasma treatment, a two-step process that cleans and activates surfaces, manufacturers can now meet product reliability and safety requirements.
Plasma Cleaning is a dry method of cleaning that turns foreign materials into a gas, thus removing molecular-level contamination residues from a surface.
Plasma Activation modifies surfaces on a molecular level to change the wettability, or surface energy. Wettability refers to the effect of a liquid to stay in contact a surface. Plasma activation enables surfaces to better maintain contact to the adhesive, resulting in high quality adhesion performance.
The process of using plasma to clean and activate a surface prior to applying an adhesive or coating to increase adhesion is a great way to improve the strength of the bond.
Microscopic contaminations not visible to the naked eye are found on all surfaces. Almost always, these contaminants must be removed as a first step to producing high-performance adhesion between surfaces when working in the application of gluing, printing, painting, bonding, or coating.
Plasma activation significantly increases the reliability and performance of a product. This increase in reliability leads to a decrease in scrap and cost of manufacturing in a production value stream. This is why plasma activation is an important part of manufacturing where a bonding process is incorporated in building a product
