Information on use

Usage time 8 h / 20 °C
Pot life 3 d / 20 °C
Drying 3 h / 20 °C
Stackable after > 16 h / 20 °C
Complete drying 7 d / 20 °C
Surface preparation

Perform cleaning by sanding on foil or melamine before coating.

Substrate sanding grits from-to 150 - 320
Lacquer sanding (grit) from - to 320 - 400
Finishing With the same product. If absolute metal marking resistance and colour abrasion resistance or another gloss level is required, final lacquering should be with Hesse MEGA-PUR DE 56x(gloss level) or UNA-PUR DE 55x(gloss level) for example.
Comments on sanding With direct coating on cleaned or sanded laminates, please test a sample application for proper adhesion! With a final lacquering of DB 525-(colour tone) with high gloss, intermediate lacquer sanding with 600 - 800 grit is recommended.
Yield per coat 7 - 13 m²/l

The spreading rate is heavily dependent on the type of application. The specifications relate to a liter of ready-for-use product, if necessary including hardener and thinner.
Storage temperature 16 - 40 °C
Working temperature 20 °C
Processing instructions The total application amount in wet film for use as a flame retardant coating for seagoing vessels is 130 g/m². Please apply a test coating to check adhesion when directly coating cleaned or sanded laminates! Harden at 5 : 1 using DR 470 for especially heavy duty surfaces and on critical substrates. Hardening at 10 : 1 with DR 471 is required for direct coatings onto MDF. Complete drying can be accelerated by hardening at 10 : 1 using DR 485 (in this case note the shorter pot life). Hardening at 5 : 1 using DR 4076-0001 after prior mixture of 5 % Glass lacquer additive EL 460-0025 to lacquer products also enables the lacquer to be applied directly onto glass following prior cleaning as per instructions.
Particular instructions This product may only be combined with other approved and technically suitable products when it is being used as a flame-retardant coating material for seagoing vessels according to the latest version of SOLAS 74/88 Regulations II-2/3, II-2/5 and II-2/6, IMO Resolution MSC.36(63)-(1994 HSC-Code) 7 and IMO Resolution MSC.97(73)-(2000 HSC-Code) 7. Pre-priming is possible depending on the required finish and carrier material, e.g. using DP 4755-9343 und DP 4791-9343 / DP 491-9343. If absolute metal marking resistance and colour abrasion resistance or another gloss level is required, we recommend top coating with the likes of MEGA-PUR DE 56x(gloss level) or UNA-PUR DE 55x(gloss level).
“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 of less than 18 °C and 40 % RH, ideal values: 20 - 25 °C, 50 - 65 % RH. Deviations from these guidelines may lead to problems with drying or hardening. Any mixed lacquer left over from the previous day should only be used as a 10 - 20 % proportion added to a fresh lacquer/hardener mixture. Old lacquer/hardener mixtures impair the surface quality (bonding/resilience). Freshly bleached woods must undergo intermediate drying for at least 48 h / 20 °C before overpainting 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 apply a test coat under real conditions!
