| Processing instructions |
It is possible to apply one to three-coats at 100 - 130 g/m² on suitable substrates. The maximum application amount in wet film totals 300 g/m². Forced drying is possible at up to 50 °C.
|
| Particular instructions |
Hardening with DR 4070 at a mixing ratio (by volume) 5 : 1 enables it to be used on bleached surfaces.
|
| 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!
