Bestimmung des Schälwiderstandes von flexiblen Oberflächenschutzsystemen

Using the example of peel resistance of flexible polyurea coatings it could be demonstrated that additional proof of quality for coating systems do not only apply in the laboratory, but also in practice. This parameter may provide crucial additional statements on the adhesion of surface protection systems. To determine the peel resistance, a special test apparatus was developed. The test procedure could be successfully applied both in the laboratory and on coated concrete surfaces at the object. By means of the empirical comparison between the lab results and the minimum peel strength of about 1.0 N/mm found in practice at the object, this additional parameter could be derived in relation to the evaluation of the adhesion of a coating system.
