polyshieldPOLYSHIELD ARC-9® has been successfully fielded on roofs for over 15 years.  This spray applied Polyurea creates a seamless, high-strength elastomeric membrane over metal, polyurethane foam and concrete.

POLYSHIELD ARC-9® is hydrophobic (resistant to moisture). It reflects sunlight to help lower surface temperatures, because of it’s aluminum additives that deter UV rays’ penetration.


  • Fast-set; dries in minutes, not hours.
  • Lowers surface temperature by reflecting sunlight.
  • Extended tack time; allowing deeper surface penetration.
  • Applied in single application.
  • Eco-friendly, 100% solids with no solvents or VOCs.
