Holiday Pinhole Detection
BlastOne’s offering of pinhole holiday detection instruments are reliable tools in ensuring the quality of the applied coating. The instruments conform to all major industry standards, including NACE, ISO, ASTM, and ACA, for pinhole/holiday detection.
Protective coatings are used to prevent corrosion on structural steel surfaces, but areas of thin or compromised coatings may not be immediately visible to the naked eye. These defects in the applied coating, known as pinholes or holidays, can adversely affect the longevity of the protective coating.

INDLPDWET
When pinholes are too small that the water cannot reach the conductive substrate underneath, the use of a wetting agent can help lower surface tension, allowing the solution to better penetrate the pinhole.
- Includes two 60mL bottles
