Readers dispel concerns about water-based adhesives

I am writing regarding "A growing concern," December 2011 issue, page 12, by Mark S. Graham, NRCA's associate executive director of technical services.

Water-based adhesives, similar to all roofing products, are subject to certain limitations. In the case of water-based adhesives, the limitation is minimum application temperatures. The article fails to mention the significant benefits of these products. Beyond the obvious advantages of their low volatile organic compound content (less odor, reduced risk of ignition on the roof), they are easier, much faster to install and much less sensitive to application errors than their solvent-based counterparts.

Our water-based membrane adhesive was introduced in 1979. Since that time, it has been used successfully on hundreds of millions of square feet of PVC roof system installations throughout the U.S. and world. Many of our oldest installations, which have been in place for decades, still are in service and were installed using our water-based adhesive.
