The porosity detector Elcometer 266 provides accurate detection of pinholes, flaws, inclusions and bubbles in coatings. The gauge has been designed to revolutionize high voltage testing of coatings, making it safer, easier, and more reliable than ever.
|Detecting the porosity and corrosion points
Premature corrosion of a substrate is usually caused by the failure of the coating. A major cause of failure is the presence of defects in the finished coating.
Commonly appelésporosité coating, the main types of deficiencies are described below:
Flows and drips
The wet coating moves under the action of gravity leaving a thin dry film. Retraction Occurs quet a coating does not flow sufficiently to cover the gaps created by the bubbles released at the surface of the coating.
Occurs quet the substrate is wet if the coating has poor flow characteristics, thus creating voids in the coating. Pitting caused either by the presence of air is then released from the substrate or imprisonment particles (dirt, sand, etc.) that do not remain in place.
If too much paint is applied to a substrate, the coating cures quet, it can crack due to internal stress of the coating.
Areas are not coated or coating
acoulé without covering the corners (specific areas of a substrate) and seals. In addition, on a rough surface, a sufficient thickness can leave uncoated areas.
The resulting costs in terms of repairs and lost production can be considerable. Early defect inspection of the coating will prevent the expense and inconvenience caused by a failure of the coating.
