| Processing instructions |
Single-coat application at 80 - 100 g/m² is possible on prepared colour lacquer surfaces. In a mixing ratio (by volume) 5 : 1 with PU Hardener DR 4076-0001, after prior mixing in of 5 % Glass lacquer additive EL 460-0025 as a lacquer component, it can also be used for direct coating on glass. The glass surface must be carefully cleaned and this should be performed using Cleaning thinner ZD 101. If a coloured finish is subsequently to be applied, please also harden UNA-COLOR DB 45245-(colour tone) or UNA-THIX-COLOR DB 45205-(colour tone) with PU Hardener DR 4076-0001 at a mixing ratio (by volume) 5 : 1.
|
| Particular instructions |
Metallic lacquers must be uniformly applied. The application quantity, application methods and drying conditions all significantly influence colour tone and effect. Pre-priming is possible depending on the desired finish and substrate, for example by using DB 48885-(colour tone), DB 45245-(colour tone) or DB 45205-(colour tone). The reflection and multicoloured effects can only be achieved on a black substrate.
|
| 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!
