What makes the urethane/silicone roof coating system better than just silicone? It’s synergy.


SYNERGY is defined as the interaction of elements that when combined produce a total effect that is greater than the sum of the individual elements. The urethane plus silicone roof coating system, better known as Ure-A-Sil, from American WeatherStar combines the best of both products.


While its UV stability and resistance to ponding water are unsurpassed, silicone isn’t known for its strength or durability against physical damage. That’s why we toughened up our Ure-A-Sil system by adding a base coat of urethane to introduce a ROOFING SYSTEM that gives you the best of both worlds: superior strength and excellent UV stability. Silicone has a scientific hardness rating comparable to a standard pencil eraser, yet the rating for urethane matches the strength of an automobile tire. Which do you trust more to protect your roof, and your business, against damage from wind-driven debris and traffic?
