  • Paint and surface coating air permeability demonstration and testing apparatus
    Patent number: 6196055
    Abstract: A method and apparatus for testing the vapor or gas permeability of a paint, sealant, textured coating or other surface coating. A test block is provided having a porous substrate coated with the test coating. The test block is mounted in a bubble testing apparatus between a pressure chamber and a liquid vessel. Water is provided in the liquid chamber and air is pumped into the pressure chamber. As the pressure of the pressure chamber rises above that of the liquid chamber, a pressure gradient is created. Bubbles can be visually observed in the water filling the liquid chamber if the test coating is vapor or gas permeable.
