Plasma Treatment Services & The Use of Corona and Plasma Treatment to Modify Contact Angle
Plasma Knowledge: Plasma Treatment Services
Plasma Treatment Services
Thierry Corporation offers customizable services to its customers. We can test samples or conduct surface analyses at no cost to you. Thierry can aid its customers in choosing the best plasma treatment system suited for their needs and help set up the plasma technology equipment. Customers may choose to outsource the plasma treatment process to Thierry to save internal time and resources. The knowledgeable experts at Thierry can optimize results whether the customer needs to plasma clean, activate, etch, or coat. Another option is to rent instead of purchasing the plasma treatment equipment. Thierry is also ready to assist in any routine maintenance and upkeep of your plasma treatment system.
The Use of Corona and Plasma Treatment to Modify Contact Angle
Surfaces exposed to the atmosphere may have microscopic impurities that cannot be seen with the naked eye, and plasma treatment may be utilized in order to plasma clean the surface of the material and remove these impurities. These impurities may have a negative impact on the contact angle and, thus, the surface energy and wettability of the surface. The contact angle is defined as the angle between the tangent line at the contact point and horizontal surface of the material. Certain materials like polymers have low surface energy.
Corona and plasma technology are two ways to plasma clean the surface and to increase the surface energy. In general, as the time of plasma treatment increases, the contact angle decreases. A lower contact angle results in a higher wettability which improves adhesive properties. PlasmaAPC 500, Thierry’s corona technology system, has a potential, and is widely used for treating plastics. PlasmaAPC 500 also uses gases from the atmosphere as the process gas. While atmospheric pressure plasma systems are ideal for smaller treatment areas, the corona system can treat a larger surface area (approximately a width of 50-60 mm).
