SPRAY GUNS
Adjust in order – Set the fan first, then adjust air pressure and material, then give it a test.
Recommended setup – Thanks to extensive research, PPG can provide spray gun settings that give the best result for each product. For example, applying clearcoat with a SATAjet 5000 B – fan 3⁄4 to full open, 1.8 to 2.2 Bar and material two turns out from closed. For more information, check the PPG
Product Data Sheet, speak to your Territory Manager or request a spray gun setup wall chart.
HVLP or RP – For basecoat, HVLP technology works
best because it applies colour more evenly so blends
are easier, there is less risk of mottle and it tends
to use less product. For example, a HVLP 1.3 fan
setup makes it easy to apply difficult colours, such
as coarse silvers and charcoals. When it comes to
clearcoats, RP technology is great for helping to accurately match the OEM finish. For best results, it is also a good idea to switch between different nozzle setups depending on whether you are using a ‘medium solids’, ‘high solids’ or ‘ultra high solids’ clearcoat.
Note: The PPG Training team can help you make the right selection.
Check gun performance regularly – Nozzle sets don’t last forever so when you get a new set, keep a sprayout of the spray pattern and check regularly to see if components need replacing.
