When your surface is lower than the dew point temperature, which is based upon temperature and humidity, it starts to get condensation. If you have an area with a 60F dew point, a pipe with cool water inside at 45F will start to sweat because its 15 degrees below the dew point.
For applications that are about 18-20 degrees F below the dew point temperature, Syneffex coatings can provide an excellent solution to stop the condensation. For larger differentials, they can help to lessen the sweating and will also protect the underlying surface from moisture and related corrosion and mold.
The Vernon Bank in Louisiana was thrilled to have a solution for the aluminum framed skylight which was dripping condensation onto their customers heads. After spraying a few coats of Syneffex coating over it, their problem was solved.
