Processing instructions When lacquering critical carriers, we recommend hardening the lacquer/hardener mixture by 5 : 1 with the PU hardener DR 4070.
Particular instructions To prevent problems of bonding between the coating layers, the surface of clear lacquer that has already been applied and sanded back must be coated with the desired subsequent coating material within one working day (8 h at 20 °C). Repeated slight sanding will be required if this time is exceeded! Please test the lacquer under real conditions, if necessary.
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!
