Silicone vs. Acrylic Coatings

Silicone is the smart choice when compared against 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 are in-organic, high solids coatings that will not degrade, chalk or crack under even the most extreme UV attack.

Stays Strong in Ponding Water - Traditional elastomeric/acrylic roof coatings are water-based and cure when water evaporates. When ponding 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. WDG HSS 535 is a non-water based, high-solids silicone roof coating. As such, when ponding water is present, WDG HSS 535’s 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%.

WDG HSS 535 Silicone Roof Coating is the best there is - there's no comparison. Silicone topcoats and sealants from WDG are contractor friendly, durable, and environmentally responsible.
