It can be apply with spray, Calderin, Airless, Airmix and Electrostatic guns.
For conventional aerographic systems use 1,5 to 1,8 Mm nozzles and 2,5 – 3 Atom of pressure. For Airmix use 0,4 mm nozzles and 3 Atom of material pressure and 3 Atom of air pressure.
In order to achieve a perfect finish, then always apply with a temperature between 10-25ºC and relative humidity between 50%-75%
Depending on the application equipment used and the environmental conditions we will have to adjust the type and quantity of solvent we use.
Nevertheless, as a general rule, use the 540421 Average Evaporation Solvent, more or less 5-10%. In case of high temperatures dilute 5-7% with 540424 Slow Evaporation Solvent, achieving better dearation and extensibility

During product drying time, prevent air currents because they will dry the surface of the film causing such problems as dearation, undulations and lack of extensibility. Some times in pressurized cabins, the air intake goes directly to the pieces which are drying, and the problems aforementioned appear. It is important take into account this question.
