Product Application Slideshow

IRON SENTRY is a product line of MCPU Polymer Engineering LLC, the manufacturers. Contracting is done through a network of qualified installers who are located locally and are a different legal entity from MCPU. Under the direction of our president, Dr. Thomas Garrett, our team of Ph.D. chemists has perfected the state of the art polyurethane roof coating. Dr. Garrett and his staff, in an effort to follow the lead of the EPA, were able to remove all Mercury from the formula and retain the resilience that made IRON SENTRY revolutionary while at the same time increasing the physical strength of the product.
