Fields of application

DG 45205-(colour tone) can also be used for shopfitting and all interior fixtures and fittings, including in kitchens and bathrooms as well as the fitting out of ship interiors. Aside from that, the product can be used with different types of hardeners and mixing ratios

Technical specifications

Yield per coat 7 - 13 m²/l

The spreading rate is heavily dependent on the type of application. The specified theoretic spreading rate reduces by up to 40 % with spray applications. Brushing or manual application methods are virtually loss-free. The specifications relate to a liter of ready-for-use product, if necessary including hardener and thinner.

Surface preparation Perform cleaning by sanding on foil or melamine before coating.
Substrate sanding grits from-to 150 - 320
Intermediate lacquer sanding (grits) from-to 320 - 400
Finishing

With another coat of the same. If complete ring resistance and abrasion resistance, or a different gloss level, is required, then please use Hesse PU Multicoat lacquer DE 4503x(gloss level) or DE 4259x(gloss level) for the final coat.
Comments on sanding
When directly coating cleaned or sanded foils, please apply a test coat to check the bonding. When applying a final coat of Hesse PU Coloured lacquer DB 45205-(colour tone) with high gloss, intermediate lacquer sanding with grit 600 - 800 is recommended.
Working temperature 20 °C
Processing instructions The maximum total application amount when being used as a flame-retardant coating agent for seagoing vessels is 130 g/m². When directly coating cleaned or sanded foils, please apply a test coat to check the bonding. For particular strains on the surface and on critical carriers, harden with DR 4070 to the ratio of 5 : 1. A hardening additive ratio of 10 : 1 with DR 4071 is necessary for direct coatings onto MDF. A hardening additive ratio of 10 : 1 can accelerate complete drying (pay attention to shorter potlife here). The hardening additive ratio of 5 : 1 with DR 4076-0001 following prior mixture of 5 % Glass lacquer additive EL 460-0025 to lacquer products also makes it possible to apply the lacquer directly onto glass following prior cleaning in accordance with regulations.
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 and DP 4791-9343. If complete metal-marking and abrasion resistance or a different gloss level is required, then we would recommend using Hesse PU Multicoat lacquer DE 4503x(gloss level) or Hesse PU Multicoat lacquer DE 4259x(gloss level) for the final coat.
“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 and dried at material and room-temperatures below 18 °C and 40 % RH. Ideal values are: 20 - 25 °C, 50 - 65 % RH. Deviations will result in drying or hardening errors. 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. Old lacquer and hardener mixtures affect the surface quality (adhesion/resistance). Freshly bleached substrates must undergo intermediate drying for at least 48 h at 20 °C before coating with suitable PU lacquers. If stored correctly (at least 20 °C room temperature), the final hardness of the coating is achieved after a week.
Please apply a test coat under real conditions!
