Processing instructions Hardening the lacquer / hardener mixture (by volume) at 5 : 1 with PU Hardener DR 4070 or 10 : 1 with PU Hardener DR 4071 is advisable for coating critical substrates or to optimise chemical and mechanical resistance. Hardening the lacquer / hardener mixture (by volume) at 5 : 1 with PU Hardener DR 4076-0001 after prior mixing of 5 % glass lacquer additive EL 460-0025 to the lacquer components also enables direct lacquering on glass. The glass surface to be lacquered should be cleaned properly beforehand using Hesse Glass cleaner ZD 101.
Particular instructions This product can only be combined with other approved and technically suitable products when used as a flame-retardant coating material for seagoing vessels in accordance with SOLAS 74/88 Regulations II-2/3, II-2/5 and II-2/6, in the latest version, IMO Resolution MSC.36(63)-(1994 HSC-Code) 7 and IMO Resolution MSC.97(73)-(2000 HSC-Code) 7. The maximum application amount in wet film when used as a flame retardant coating material for seagoing vessels is 150 g/m². The dull matt configuration of DE 42590 and the extra matt formulation of DE 42590-0007 (please observe the separate technical information) must not be used as a multicoat lacquer, but only as a 1-coat finish! Hesse PU Multicoat lacquer DE 4259x(gloss level) is ideally suited as a finishing coat on top of Hesse PU Colour lacquer DB 4524x(gloss level)-(colour tone) and provides outstanding metal-marking resistance. Hesse PU Colour lacquer DB 4524(gloss level)-(colour tone) can be used to tint Hesse PU Multicoat lacquer DE 4259x(gloss level). Pre-priming is possible depending on surface requirements and substrate, e.g. using Hesse Base coats DG 4741, DG 4734, DG 4717-0004, DG 4768-0004 and DG 4763. “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!
