What is a TyhVLP spray gun?
Conventional spray guns have been around a long time and are widely used in the market place. TyHVLP (High Volume Low Pressure) spray guns can improve transfer efficiency to around 65 per cent but there appears to be limitations with control of the finish either because the spray guns are very sensitive to small pressure fluctuations or they produce unacceptable levels of orange peel. Some manufacturers view HVLP as old, even superseded, technology having been in the market in excess of 30 years. As the name implies, the guns need large volumes of air to produce even a marginally satisfactory finish. Air usages of 16 cfm and higher are most common and the low air cap pressure of 10 psi can leads to average atomisation of today's high solid paints. Operators have a tendency to increase pressures above recommended levels to increase application speeds and atomisation quality and thus create even greater problems with air consumption whilst at the same time reducing transfer efficiency
What is the purpose of a clear over base spray gun?
New technology paints rely more heavily on controlled minimum paint thickness or film build to achieve their characteristics, often using clear over base application to achieve the colour and gloss required. It is at this point that consistency of spray pattern becomes an important feature of the spray gun, allowing the lowest possible amount of paint to achieve the desired finished result. In most cases this is achieved more satisfactorily with the latest technology HTE High Transfer Efficient equipment, producing results with less mottle, which is difficult to control with heavy metallic basecoats particularly with high silver levels.
What is transfer efficiency?
Transfer efficiency (TE) is the amount of paint that actually hits the panel as a proportion of the total paint used. So a typical HVLP gun might allow two thirds of the paint in the cup to hit the panel. That ratio is potentially even higher with the new generation of HTE guns. Why is a higher TE good? Because more paint hitting the metal means less paint wasted and less paint in the atmosphere.
How to test a gun?
1. Take a test spray: Manufacturer's claims sound good on paper, but find out exactly how a gun feels, responds and performs by testing it yourself. Factor in consumables usage when considering the costs of different gun types. 2. Air: Clean, dry air is the foundation to a good spray application.
