| Particular instructions |
In the case of metallic and effect lacquers, a uniform application for cloud-free surfaces is absolutely necessary. The application quantities, application methods and drying conditions influence the colour tone and effect. The colouring for the Hesse chrome effect can also be achieved with PU Brillant-Color DB 44099-9005 with a mixing ratio (by volume) of 2 : 1 with PU Hardener DR 4080. For stronger mechanical stress, or if another gloss level is desired, the Hesse multicoat lacquers from the DE 4259x(gloss level), DE 4503x(gloss level) and PU Acrylic brilliant lacquer DU 45229 ranges can be applied as a top coat after drying for 2 - 3 h / 20 ° C without sanding. The additional top coating influences the chrome effect!
|
| 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!
