Surface Pretreatments & Adhesion Bonding

Most adhesion problems on plastics start at the surface. This topic gathers the articles on surface pretreatment, meaning corona discharge, atmospheric and blown-arc plasma, flame and Pyrosil treatment and UV/ozone, together with the adhesion bonding work that depends on them: surface energy and contact angle, adhesive selection, joint design, bonding semi-crystalline resins, and reading a failed bond to tell adhesive, cohesive and substrate failure apart. The surface pretreatment and adhesive bonding service pages describe the engineering offer, and the free surface energy calculator turns a dyne or contact-angle reading into a wetting verdict.
