Waterborne Basics
There are two different types of waterbase on the market currently; true latex systems and solvent hybrid systems. The difference between the two is easily identified as hybrids use a traditional can with a mixing lid and mix machine. Latex systems use a plastic container that is not agitated. Of critical importance are air movement in the booth, as well as the condition of the air supply used for spraying: Once the commitment has been made to waterborne base coats all aspects of maintenance need to be addressed including cleanliness of booths, cars, and painters themselves. The need for creating turbulent air inside the booth can create increased dirt in the jobs without careful scrutiny. Booth filters must be changed regularly, and burners should be serviced on schedule. Air compressors as well as refrigerated and desiccant dryers must be maintained and serviced with care. A note on safety: Just because you are now spraying a "green" product which is supposed to be better for the environment, it does not necessarily mean it is safer to you. Our bodies are made up of over 50% water, so they react differently to solvent as opposed to waterbase. Just as before, personal protection, such as gloves, spray suits and masks (supplied air) is still equally if not more important. Return from Waterborne Basics to Home

Having the ability to increase spray temperature by 10 degrees will help considerably. In other words, there may be times in the summer where painters will need to fire the burners in their booth to increase spray temperature for spray and Flash-Off modes based on the brand of waterborne base coat. Example: 80 degree days with 80% RH take spray temperature to 90◦F.
