Polymer Surface Treatments for Enhanced Adhesion
Which surface treatment technique is best for you?
Mechanical – involves blasting with abrasive particles to develop a surface roughness to the polymer. This technique may be wet or dry.
Heat and Flame – the polymer surface is quickly exposed to a high temperature flame. This operation anneals and oxidizes the polymer surface
Radiation – this treatment involves exposing the polymer to UV or gamma radiation. The resulting surface typically is oxidized and crosslinked.
Plasma – Truly this is the most elegant and broad reaching method for polymer activation. This technique treats the surface of polymer with activated gaseous compounds. The activated gases are usually produced with RF discharge and can oxidize, crosslink, and clean the polymer surface.
Electrical – Electrical arc blow or corona discharge are used in this method. This treatment usually oxidizes and crosslinks polymer surfaces.
Chemical – Chemical agents that oxidize, dissolve, hydrolyze, or swell polymer surfaces. This process can add surface topography and/or chemistry.
