Particular instructions The product is not suitable for use on bleached surfaces! Greying may occur if multiple coats are applied or in the event of greater coat thicknesses on dark woods or stains. Our recommendation for these purposes: DG 4708-0003. Do not use the product on light woods or woods stained with non-wood stain colours! DG 4708-0015 is a suitable basecoat for electrostatic application with DU 4401x(gloss-level)-0003 as the top coat. The conductivity can be adjusted with NR 1075, as necessary. Add around 0.05 to 0.1 %.
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!

The coating process and the precise treatment parameters are adapted in each case to the respective application and drying conditions and can be found in the customer-specific process descriptions (surface techniques).
