| Processing instructions |
You can apply two or three coats at 80 - 150 g/m². The maximum application amount in wet film totals 350 g/m2. The following Hesse hardener types can be used to improve the water and PVC resistance of PURA-TWIN: mixing ratio 25 : 1 by volume with DR 470 / DR 4070 or mixing ratio 50 : 1 with DR 471 / DR 4071. In each case the pot life is 5 h at 20 °C. Older hardener-lacquer mixtures no longer offer the desired resistance!

| General instructions on workmanship |
Please test the lacquer under real conditions, if necessary.

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).
