default-features-benifits.png
High Performance Durability
  • The single component, silyl-terminated polyether (STPE) formulation of DuPont™ LiquidArmor™ FJ is not water-soluble and will not lose physical properties or wash off the wall when exposed to liquid water, even before curing.
  • Passes AAMA 714, Specification for Liquid Applied Flashing Used to Create a Water-Resistive Seal Around Exterior Wall Openings in Buildings.
  • Excellent elasticity, with over 90% recovery at 300% elongation.
  • Can be installed on damp surfaces, which is defined as when no moisture is transferred to the skin when the substrate is touched.
  • LiquidArmor™ FJ may be exposed to UV for 270 days (9 months).
