Particular instructions PU Diamond finish has been tested according to the standard test procedure American Society for Testing and Materials ASTM D7027-20 to determine the scratch resistance. The tested sample DU 590 did not show any scratches at a load of 400 g. The tested sample DU 594 did not show any scratches at a load of 500 g. In addition, DU 59x(gloss level) was tested according to the standard test method ASTM D2794-93 to determine the effects of rapid deformation by impact. Detailed results can be found in the test report. Because of the slightly abrasive surface structure, the product is of only limited suitability for the final finish of coloured surfaces. The Hesse PU Diamond Seal is not absolutely proof against metal marking. Because of its slightly milky colour, use on dark woods, over stains or coloured varnishes is not recommended. Depending on the desired surface and base material, priming can be carried out with, e.g. Hesse primers DG 572-1, DG 534 and DG 417.
General instructions on workmanship PU lacquers should not be applied and dried at material and room-temperatures below 18 °C and 40 % RH. Ideal values are: 20 - 25 °C, 50 - 65 % RH. Deviations will result in drying or hardening errors. In order to avoid adhesion problems, please sand the PU lacquered surfaces before applying fresh lacquer and apply lacquer to the sanded surfaces as soon as possible. Old lacquer and hardener mixtures affect the surface quality (adhesion/resistance). Freshly bleached substrates must undergo intermediate drying for at least 48 h at 20 °C before coating with suitable PU lacquers. If stored correctly (at least 20 °C room temperature), the final hardness of the coating is achieved after a week.
Please apply a test coat under real conditions!
