Information on use

Usage time 5 - 6 h / 20 °C
Pot life 8 h / 20 °C
Drying 16 h / 20 °C
Stackable after > 16 h / 20 °C
Complete drying 7 d / 20 °C
Surface preparation All grease must be carefully removed from the substrate prior to use as an adhesion primer. When directly coating cleaned or sanded laminates or when using as an adhesion primer on plastics, please make a test lacquering for proper adhesion!
Substrate sanding grits from-to 150 - 400
Lacquer sanding (grit) from - to 320 - 400
Finishing After renewed slight sanding it can be recoated with itself or matching products. (e.g. DE 4259x(gloss level), DE 4503x(gloss level), DB 4524x-(colour tone), DB 4520x(gloss level)-(colour tone))
Yield per coat 5 - 10 m²/l

The spreading rate is heavily dependent on the type of application. The specifications relate to a liter of ready-for-use product, if necessary including hardener and thinner.
Storage temperature 16 - 25 °C
Working temperature 20 °C
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).
