Abstract

This invention refers to a unit for determining the carbon dioxide permeability of coatings, comprising a thermostatic cabinet (10) containing inside a permeation cell (11), a CO2 specific analyser (12), a mixing container (13), three pressure transducers (14) and two mass flow controllers (15) to regulate the feeding stream in the permeation cell. This unit is connected to a data processor (16) and applies the Wicke-Kallenback method. The project of the carbon dioxide permeability of coatings determining unit was performed in order to promote its functionality and effectiveness. With this unit it is possible to get results in a short period of time, which is a major benefit in comparison with other existing methods. The coatings are applied on Kraft paper, as a result of its effectiveness in these tests and its low cost.
