Abstract
An experimental effort has been undertaken to examine the effect of surface treatment on various low surface energy thermoplastic materials to promote wettability and bondability of these substrates. Changes in wettability were followed by contact angle measurements. These measurements were correlated with the bondability of treated surfaces using a usual twopart epoxy adhesive. Air-plasma cleaning is a more effective treatment than the usual chemical-acid etching in increasing the surface energy of polymers to make them more wettable and bondable, except for polypropylene and for polytetraf luoroethylene. This work has enabled several satisfactory solutions for bonding these substrates by selecting suitable surface treatments and adhesives for each.
