Information
Pinhole & Porosity Detection
Premature corrosion of a substrate is usually due to the failure of the coating. A major cause of failure is the presence of flaws in the finished coating. Collectively referred to as a coating’s porosity the main types of flaw are described below:
 
  • Runs & Sags:
    The wet coating moves under gravity leaving a thin dry film.
     
  • Cissing:
    Occurs when a coating does not re-flow to cover the voids generated by air bubbles being released from the surface of a coating.
     
  • Cratering:
    Occurs when the substrate is wet or if the coating has poor flow characteristics, thus creating voids in the coating.
     
  • Pinholes:
    Caused either by air entrapment which is then released from the surface, or by the entrapment of particulates (dust, sand, etc.) which do not stay in place.
     
  • Over Coating:
    If too much coating is applied to a substrate, as the coating cures it can crack from internal stresses of the coating.
     
  • Under Coating:
    Areas are not coated, or the coating flows away from particular edges, corners of a substrate and welds. Furthermore over a rough surface profile, insufficient coating may leave the profile’s peaks exposed.
