Chemlink M-1 is their flagship product and the one that our customers rave about. It was designed for commercial and industrial roofing and holds up to all weather conditions for a very long time. It bonds well to almost any surface and will not shrink or discolor. It can compress and expand up to 35% without breaking and it can handle very cold, damp or dry conditions. Meets or exceeds ASTM C920, Type S, Grade NS, Class 35, ASTM E84, Class A, and many other standards. VOC = 17 g/l. See specs on our website for more details.We've been using this ourselves for almost 15 years outdoors in Iowa weather without degradation, shrinkage, cracking or any form of change. Most manufacturers will not say a product lasts "forever". Because we don't sell the 3nm 520, we are unable to compare the two.
