Cool Roof Coatings and Paints

Acrylic roof coatings, such as SolarEx 300 and TropEx 310, are water-based, low-VOC formulations that provide strong UV protection, dirt pickup resistance, and high tensile elongation on sloped roofs and masonry. In contrast, silicone coatings like SiliconEx 500 are solvent-free, moisture-curing formulas that deliver hydrophobic performance and permanent resistance to standing or ponding water on flat or low-slope roofs.

Yes, silicone formulations like SiliconEx 500 are specifically engineered with hydrophobic properties to withstand permanent ponding water without softening or degrading. While standard water-based acrylic coatings require positive drainage and slope to prevent degradation from standing water, moisture-cure silicone forms a seamless waterproofing membrane that maintains its physical adhesion and reflective performance under continuous water immersion.

SolarEx cool roof coatings adhere to a wide variety of commercial and residential substrates. Depending on the specific product formulation, compatible surfaces include metal, concrete, masonry, wood, asphalt shingles, built-up roofing, mineral cap sheets, and single-ply membranes such as TPO, EPDM, and spray-applied polyurethane foam. Primers or paired undercoats like ElastEx 200 or SealEx 100 may be used for complete waterproofing systems.

SolarEx cool roof coatings can be applied using an airless spray system, roller, or brush. For large-scale commercial installations, high-pressure airless spraying at 3,000 PSI or higher allows for rapid, uniform coverage across wide surface areas. Small-scale applications or detailed flashings, penetrations, and vertical architectural walls can be completed using standard commercial paint rollers and heavy-duty brushes.

Properly applied cool roof systems provide extended protection depending on the product and system configuration. SolarEx 300 acrylic topcoats last 10 to 15 years when properly applied. Elastomeric TropEx 310 systems offer 10-year configurations, while SiliconEx 500 moisture-cure silicone systems offer up to a 20-year material warranty based on the chosen system and applied thickness.

Yes, SolarEx provides color options beyond standard reflective white. SolarEx 300 features custom color matching utilizing a 1,020-color fan deck alongside major brand collections. TropEx 310 is readily available in White, Gray, Tan, and custom colors. These formulations maintain solar reflectivity while meeting specific aesthetic and architectural requirements for commercial buildings and residential exteriors.
