The VF2200 permeation cup is used to determine the water vapor transmission rate of paints, varnishes, coatings, coating systems and related products. The permeable cup consists of a cup, a sealing ring, and a lid ring. The sealing ring is designed to prevent turning when the lid is closed. Permeabilization cups are suitable for testing both self-supporting and non-self-supporting coatings. Water vapor transport is meaningful for high humidity conditions. Therefore, the wet cup method is the reference method used to determine the water vapor transmission rate, and if otherwise agreed, other procedures or conditions of the dry cup method can be used.
