Silicone vs Acrylic Roof Coatings

Silicone is the smart choice when compared to any acrylic roof coating. A silicone restoration membrane delivers superior UV resistance, adhesion, and reflectivity.

UV Resistance - Unlike acrylic roof coatings that chalk, discolor, crack and haze when exposed to ultra violet rays, silicone restoration membranes provide an in-organic, high solids elastomeric roof coating that will not degrade, chalk or crack under even the most extreme UV attack.

Stays Strong in Standing Water - Traditional elastomeric/acrylic roof coatings are water-based and cure when water evaporates. When standing water is present on roof surfaces for a period of 48 hours or more, acrylic roof coatings can begin to re-emulsify to their liquid state and lose adhesion. In contrast, silicone coatings cure and cross-link by reaction with moisture in the air. Silicone cannot re-emulsify due to exposure to standing water. SmartRoof™ 1-Coat High Solids Silicone Roof Coating is not water-based. As such, when standing water is present, its adhesion to the roof substrate is not affected.

Reflectivity Saves Energy - Using white silicone roof coating on a roof saves building energy use by as much as 15% to 35%.
