DIN EN 15766:2009-08 EN 15766:2009 (E) 4 1 Scope This standard specifies a method for the determination of the polymerization of the internal coating of aluminium tubes
15、with acetone. 2 Principle Epoxy phenolic internal coatings are mostly used as internal coating for aluminium tubes. Acetone is a good solvent for epoxy-phenolic coatings before polymerization. Polymerized epoxy-phenolic coatings are not soluble. Therefore, when the surface of the coating is rubbed w
16、ith a piece of cotton wool soaked in acetone, if the coating has not been sufficiently hardened, there will be partial dissolution and a discharge on the cotton wool (colouring). For non-epoxy phenolic coatings, the test method shall be mutually agreed upon by customer and supplier. 3 Test device/Te
17、st media Acetone CAS No. 67-64-1. Cotton wool. 4 Procedure Cut the tube and flatten the cylindrical part. Rub 10 1 times up and down with a piece of cotton wool soaked in acetone with a pressure of approximately 10 N/cm2. Check the colour of the cotton wool. 5 Evaluation of results After rubbing, th
18、e coated surface shall not have become matt or sticky. There should be no colouring of the cotton wool, nor any apparent reaction on the coated surface. A slight coloration of the cotton wool can be accepted if no apparent reactions on the coated surface are detected. DIN EN 15766:2009-08 EN 15766:2
