Product Description

Payne - Permeability Cup

Features

  • Precision machining ensures exposure area / total film ratio of 0.4:1
  • Exposure surface: 10 cm or 25 cm
  • High grade anodized aluminium

This simple instrument allows reliable measurement of permeability to moisture of paints or similar coatings. It consists of aluminium cup, a ring and a screw cap.

After drying, a coated permeable backing material is cut out to form a disc and tightened by the cap/disc assembly onto the cup, containing 5 cm of distilled water.

The whole is weighed to 0.1 mg and placed into a dessicator at 38C. Periodic weighing every 24 hours indicates the loss of water that has permeated through the film. It is recommended to run the test in triplicate, due to film imperfections.
