National AIM VOC regulations vary from 120 g/L for low-solids wood preservatives to 870 g/L for ornamental lacquers. One of the first steps to achieve the lower VOC levels was to go to waterborne binder systems. In this case, the VOC came from the amines and coalescing aides that were needed to obtain acceptable film characteristics. VOC limits continue to be reduced, requiring the implementation of additional technologies to meet the new lower limits.
