Corona Treatment: Corona Treatment is used to increase the surface wettability of plastics. The low surface energy of polymer based substrates often leads to poor adhesion of inks, glues and coatings. To obtain optimum adhesion, it is necessary to increase the surface energy of the substrate to just above that of the material to be applied. Corona treating results in good wetting of the material over the surface of the substrate and so improves adhesion.Dyne Technology offers five distinct corona based solutions to Corona treat your plastic parts i.e. Rotating Electrode, Fixed Electrode, Spot Treater, Label Treater and Web treater systems that are all tailored to suit your specific applications. 1. Rotating Electrode; This universal corona treatment system operates with special rotating corona electrode elements resulting in complete and uniform corona treatment of the parts. It offers a cost-effective method for optimising the adhesion properties of printing inks and coatings onto 3D parts made from low surface energy polymers such as polypropylene and polyethylene. 2. Fixed Electrode; This versatile system operates using a wide range of electrode systems ranging from simple "wire" electrodes, high performance "ball" electrodes or highly durable ceramic electrode elements resulting in complete and uniform corona treatment. Fixed electrode corona treatment systems can incorporate air jets to support the feed of parts through the corona treating station. 3. Spot Treater; This corona treatment unit creates a high voltage, low frequency corona discharge to treat the surface of 3-dimensional moulded or extruded plastic parts, profiles, webs, containers, etc. An airflow presses the corona discharge towards the substrate to be treated and a counter electrode is not necessary. 4. Narrow Web Treater; This system is designed for the corona treating of conductive and non-conductive narrow webs, labels etc. This type of corona treating system can be supplied to treat either one or both sides of the web and will accommodate widths from 100-500mm, running at production speeds of up to 150m/min. 5. Wide Web Treater; This corona treatment system is designed for the flexible packaging and printing industries and offers increased surface energy on webs manufactured from a variety of materials including; paper, plastic, metalised film and foil. The compact design of the corona discharge unit enables the equipment to be easily installed into new or existing extrusion, printing, coating and laminating lines. Contact Information:
