Airbrush basecoat painting

  • Description

Before all, get a look at the Primer section

SDW Shading Colors have a different formulation compared to other acrylics. And so their use too is different.

Often, other "heavier" acrylics require large nozzles. They also require a broad dilution with specific thinners and a slow flow - lower air pressure - .

This to avoid them to dry on the airbrush tip, obstructing it. And to avoid them to dry on the course between the airbrush and the model's surface, resulting in a rough, orange peel paint layer.

Instead, let us see SDW Shading Colors behavior :

The combination of coloring micro-resins and slow drying get a higher fluidity. They encourage the use of litlle nozzles, 0.2 to 0.15. Larger nozzles, needful for other acrylics, are useless.

Most of the tasks can be done with undiluted paint. For aribrush-use thinning you can use water, alcohol - ethanol, denaturated or isopropanol -. You also can use a good number of acrylic thinners on the market, but you do not need them.

If you want a dilution, do it in a separate pot, not into the airbrush cup.

They prefer higher pressures. Per example, with an undiluted paint an Olympos hp 100 b or a Fengda BD 1800 with a 0,.2 nozzle require ab.1.5 to 2.00 bar - 22 to 30 psi. An Infinity CR Plus with a 0.15 nozzle can get a lower pressure.

Diluting them, and upon the job to be done, pressure will be progressively lowered. But it will usually be higher compared to other acrylics.

Given the slower drying time, with a double action airbrush I suggest you to spray more air and less paint than you usually do with other paints. This way you achieve a faster drying and thin, smooth layers.
