Sunshield Reflective Paints and Coatings

The purpose of a sun shield coating is to reflect incoming solar radiation and ultraviolet rays away from the roof surface. By minimizing solar heat absorption, sun shield coatings lower roof surface temperatures and reduce indoor cooling loads. Additionally, these coatings act as protective barriers against severe weathering, moisture, and ultraviolet degradation, helping extend the overall service life of compatible roofing substrates.

Yes, heat reflective paint works by utilizing specialized pigments like titanium dioxide to reflect solar radiation away from roofing substrates. Formulations such as SolarEx 300 reflect 90% or more of ultraviolet and infrared radiation, while acrylic elastomeric coatings provide high solar reflectivity. By preventing solar heat from absorbing into the building, reflective coatings reduce surface temperatures and help lower interior cooling demands.

Reflective coatings are compatible with a wide range of commercial and residential roofing substrates. Depending on the specific formulation, they can be applied over metal roofs, concrete, masonry, wood, asphalt shingles, built-up roofing, modified bitumen mineral cap sheets, and single-ply membranes such as TPO and EPDM. They can also be used over spray polyurethane foam roofs and existing elastomeric coating systems.

Yes, high-grade silicone formulations such as SiliconEx 500 are designed with hydrophobic properties that provide permanent ponding water resistance. Unlike water-based acrylic coatings that may soften under continuous ponding, 100% silicone creates a moisture-cured, seamless waterproof membrane. This makes silicone reflective coatings an effective solution for flat or low-slope roofs that experience recurring standing water or slow drainage.

Titanium dioxide acts as a premier reflective pigment in coating formulations. In products like SolarEx 300, incorporating five times higher titanium dioxide pigment levels enables the coating to reflect 90% or more of ultraviolet and infrared radiation. This high pigment concentration creates an abrasion-resistant, durable film that resists dirt pickup, prevents ultraviolet breakdown, and maintains solar reflectance over the coating service life.

Reflective roof coatings can be applied using professional airless spray equipment, medium to heavy-nap rollers, or brushes for detail work and penetrations. For spray applications, acrylic coatings like SolarEx 300 require an airless sprayer capable of 3,000 PSI or higher. Proper surface cleaning and preparation are necessary to achieve optimal adhesion across metal, membrane, single-ply, or asphalt roofing substrates.
