Temperature Compound relationships

As we look forward to warmer weather, we need to keep in mind the dynamics and parameters of paint and surface restoration / finishing. Ambient temperature and humidity play a big role in how your finish will appear once the process has been completed. Let’s see how this might play out.
As a general rule, it is recommended that the minimum ambient, (actual), air temperature be at least 65 degrees for buffing, polishing and or finishing. The reason for this is that compounds, polishes, sealants and waxes may contain petroleum distillates that when exposed to the air “Flash Off” or evaporate. This may happen too quickly or not fast enough depending on the type of solvent used in the emulsion. This may drastically change the lubricity factor in your operation which will have a cause and effect result in your final finish. Too much lubricity may cause the compound to be not aggressive enough while not enough will create undesirable heat leading to over aggressiveness. This lubricity factor has a cause/effect relationship with the ambient air temperature. Air temperature too hot will cause the petroleum distillate to flash off too quickly thus leading to high surface temps and high risks of burn through where too cool of temperatures will not allow the petroleum distillate to flash off at all leading to low compound performance. This concept also holds true when doing the work in the sunshine as well. With the costs of beautification rising, it is best to perform the operations within the manufactures recommend running temperatures. Doing so rewards you with the best results by maximizing the performance of your chosen system. Good Luck!
