Processing instructions DE 4503x(gloss level) can as necessary be mixed at a mixing ratio (by volume) of 5 : 1 with DR 4070 and at a mixing ratio (by volume) of 10 : 1 with DR 4071 to optimise chemical and mechanical resistance. 
Particular instructions MEGA-PUR has been tested according to the standard test procedure of the American Society for Testing and Materials ASTM D7027-20 to determine its scratch resistance. The tested sample of DE 45030 did not show any scratches at a load of 400 g. The tested sample of DE 45034 did not show any scratches at a load of 700 g. In addition, DE 4503x(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..

This product can only be combined with other approved and technically suitable products when being used as a low-flammable coating for seagoing vessels. The maximum wet application amount when used as a low-flammable coating for seagoing vessels is 240 g/m². When used as a flame retardant coating on interior fittings according to ASTM E84-16, this product may only be combined and processed as described in the test certificate from Thomas Bell-Wright. . Do not use the extra matt configuration of DE 45030 as a multicoat lacquer, but only as a 1-coat finish on top of the next highest gloss levels in the series or on a matching basecoat! Pre-priming is possible depending on the desired surface and substrate, e.g. using Hesse Basecoats DG 4720-0001, DG 4741-0001, DG 4734, DG 4717-0004, DG 4768-0004 , DG 4768-0009 and OPTI-BASE DG 4750.
Multicoat lacquer DE 4503x(gloss level) is suitable for finishing on Hesse UNA-COLOR and FANTASTIC-COLOR and its transparent finish provides excellent ring-resistance. This operation can also be used in parallel to individually determine the gloss level of the colour lacquer applied. The stipulated test certificates relate exclusively to a mixing ratio (by volume) of 10 : 1 with PU Hardener DR 4070. “A risk assessment was undertaken according to Directive 2014/90/EU, Annex II, Section 3. This coating does not pose a physical risk to health nor a risk to the environment when cured and dried.”
General instructions on workmanship PU lacquers should not be used and dried at product and room temperatures below 18 °C and below 40 % RH , ideal values: 20 -25 °C, 50 - 65 % RH. Deviations lead to problems with drying or, as may apply, hardening. 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. Mixed residues from the previous day must only be used as a 10 - 20 % aggregate in a fresh lacquer/hardener mixture. Old lacquer/hardener mixtures impair the surface quality (adhesion/stability). Freshly bleached woods must be dried for at least 48 h / 20 °C before being coated with PU lacquers. If stored correctly (at least 20 °C room temperature), complete hardening of the coating is achieved after a week.
Please apply a test coat under real conditions!
