Processing instructions The maximum overall applications for use as a flame retardant coating on board ships amounts to 200 g/m².
Particular instructions When being used as a flame-retardant coating agent 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, this product may only be combined with other approved and technically suitable products. For use as MDF edge isolation underneath coloured coating systems, prepare the mixture with 20 - 30 % DV 490 thinner and apply an additional coat on the same day following prior sanding with grit 320.

“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!
