Particular instructions When used as a flame-retardant coating agent for ocean-going vessels this product is only compatible with other technically suitable and approved products. Pre-priming is possible, depending on the surface requirements and the substrate e. g. with Hesse basecoats DG 417, 4717-0005 and the Hesse PU Coloured lacquers DB 555-(colour tone) and DB 4524x(gloss level)-(colour tone). On bleached surfaces, combination with the PU Basecoats DG 417 and DG 4717-0005 is recommended.
“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!
