Features & Benefits
High Performance Durability
- The single component, silyl-terminated polyether (STPE) formulation of DuPont™ Tyvek® Flashing and Joint Compound+ 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 99% 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.
- Tyvek® Fluid Applied Flashing and Joint Compound+ may be exposed to UV for 9 months (270 days).
Air and Water Resistance
- Tyvek® Fluid Applied Flashing and Joint Compound+ offers an ideal combination of air and water holdout along with vapor permeability.
- When installed as part of the DuPont™ Tyvek® Fluid Applied WB+™ System and/or in hybrid flashing applications with DuPont™ Tyvek® Building Wraps and DuPont Self-Adhered Flashing Products, passes air leakage testing per ASTM E2357 and water infiltration resistance up to 15psf when tested in accordance with ASMT E331.
Ease of Use
- High percent solids formulation – low shrinkage during curing, enabling single coat application.
- Excellent gunnabillity, with easy tooling when minimum ambient and surface temperatures are 25 °F (-4 °C) and rising
- Brushable and trowelable for fast and easy application.
