UV lamp for the detection of pinholes

With a durable aluminum casing and powered using batteries, UV lamp Elcometer 260 is a fast and economical solution for testing coatings and look for traces of porosity.

• 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 referred to as "coating porosity", the main types of defects are described below:
• Flows and drips: The wet coating moves under the action of gravity leaving a thin dry film.
• Crater wear: Occurs when the substrate is wet when 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.
• Over thickness: If too much paint is applied to a substrate, when the coating hardens, it can crack due to internal stress of the coating.
• Insufficient depth: the areas are not covered or the coating has flowed without covering the corners (specific areas of a substrate) and seals.
