Solar Shield is a water-borne combination of high-performance elastomeric acrylics, and resin additives which produces a tough, yet flexible coating film. Designed for performance and durability, Solar Shield contains 3 unique ceramics to block up to 89% of Solar Heat entering a structure due to Visual Light, Ultra Violet (UV), and Infrared (IR). Solar Shield is a flexible membrane with low permeability that can greatly reduce expansion and contraction of a roof. It also prevents corrosion and surface deterioration.

Typical Uses

  • As a one-coat insulation system on exteriors to block the initial loading of Solar Heat gain. (roofs and side walls)
  • As an insulation system for interior applications.
  • As insulation for transportation vehicles, refrigerated containers, reefer trucks, and railroad cars when applied to the exterior.
  • Exterior application to reduce or eliminate condensation on HVAC systems, tanks, spheres, storage systems, and concrete walls.
  • As a system over metal, concrete, masonry, and wood to stop moisture penetration and corrosion.
  • Ability to resist dirt, mold, mildew, and pollution to increase longevity, and reduce surface maintenance.
  • As a topcoat over metal roofs.
  • Applied over tent fabrics to provide insulation & remain flexible.

Application Methods

Solar Shield can be applied to metal, concrete, masonry and wood. The application can be spray, brush or roller. For specific instructions on surface preparation, mixing and application, please refer to the SPI’s application instructions for Solar Shield. This coating should never be applied at less than 18 mils wet (450 microns), 9.0 mils dry (225 microns), each coat.
