In many cases, pretreatment is an essential prerequisite for the secure adhesion of adhesive and finishing layers to plastics, metals, ceramics, paper, and glass. With Arcotec pretreatment systems, you can activate the surfaces of films, paper, and molded parts quickly and reliably with consistently high quality.
With over 50 years of experience, Arcotec GmbH is a successful manufacturer of all four methods of physical pretreatment under atmospheric pressure (corona, plasma, flame with silication). Arcotec pretreatment systems are used worldwide and are a testament to our consistently high quality and unique expertise in the field of surface pretreatment.
The surface of many polymer films and molded parts is nonpolar. Metals and glass also often have low surface tension. This means that adhesives, paints, and other finishing layers do not adhere well to them. Surface tension can be increased by appropriate pretreatment. During the pretreatment of plastics, the molecular chains on the surface are broken up, which increases the adhesive forces.
Four different physical processes are available for surface activation: corona, plasma, and flame treatment, as well as silicatization. Corona and plasma systems generate plasma through high-voltage discharges. Flame treatment, on the other hand, uses a burner with a specially adjusted flame. Silane-containing precursors are used in silicatization.
During pretreatment with plasma or flame treatment, process gases can also be added to enhance the activation effect. Flame systems also offer the option of silicatizing the treated surfaces to further improve adhesion. Our experts will advise you individually to find the most suitable pretreatment process for your needs. Feel free to contact us !
