Processing instructions The maximum wet application amount when used as a low-flammable coating for seagoing vessels is 150 g/m². A lacquer/hardener mixture of 5 : 1 with PU Hardener DR 4072 is recommended for coating critical substrates. Hardening at 5 : 1 with PU Hardener DR 4076-0001 also enables direct coating of glass after adding 5 % Glass lacquer additive EL 460-0025 to the lacquer components. Please properly clean the glass surface using Cleaning thinner ZD 101 prior to application.
Particular instructions This product may only be combined with other approved and technically suitable products when it is used as a low-flammable coating for seagoing vessels according to the latest version of SOLAS 74/88 Reg. II-2/3, II-2/5 and II-2/6, IMO Resolution MSC.36(63)-(1994 HSC-Code) 7, IMO Resolution MSC.97(73)-(2000 HSC-Code) 7. The dull matt adjustment of this PU Multicoat lacquer means that it is only to be used as a 1-coat finish as opposed to a multi-layer lacquer coating! PU Multicoat lacquer DE 51x(gloss level) is ideally suited for finishing UNA-COLOR and provides outstanding ring-resistance. UNA-COLOR DB 45245-(colour tone) can be used to tint PU Multicoat lacquer DE 51x(gloss level), but only at a maximum addition of 10 %. A maximum of 5 % Colour concentrate ZD 1-(colour tone) can also be added to configure a glazing effect in PU Multicoat lacquer DE 51x(gloss level). Pre-priming is possible depending on the desired surface finish and substrate, for example using Basecoats DG 434, DG 417, DG 468-1 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 applied or dried at material and room temperatures below 18 °C and 40 % RH, ideal values: 20 - 25 °C and 50 - 65 % RH. Deviations lead to problems with drying and/or curing. To avoid adhesion problems, please gently sand back 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 wood must be allowed at least 48 h intermediate drying / 20 °C before recoating with PU lacquers. The final hardness of the coating is achieved after one week in correct storage conditions (at least 20 °C room temperature).
Please conduct a sample coating under real conditions!
