Manufacturer: Firestone Building Products Accepted for RoofStar Guarantee Program Date TBA Product Summary UltraFlash is a flexible flashing system specially designed to work with a variety of bituminous roofing systems to ensure the weatherproofing of a wide range of details. It is a liquid applied two part system consisting of a stitchbonded polyester scrim, UltraFlash Fabric, and UltraFlash Liquid Flashing for superior bonding and durability. UltraFlash Primer can be used to improve the adhesion of the UltraFlash Liquid Flashing. UltraFlash Primer is an organo-silane compound dispersed in isopropyl alcohol. For best adhesion use UltraFlash Primer on all nonporous surfaces including all metal surfaces. UltraFlash Liquid Flashing must be applied within one hour of the application of UltraFlash Primer. If more than one hour has elapsed from initial application, reapply UltraFlash Primer. UltraFlash Fabric is a stitchbonded polyester scrim that provides a sturdy combination of burst strength and toughness for roofing applications. This flexible polyester allows elongation up to 50%, easily supporting against thermal stresses and movements. UltraFlash Liquid Flashing is a tough liquid applied urethane elastomer blend of Part A and Part B activator to form an impermeable, seamless, monolithic membrane. The material cures chemically at ambient temperature to form a tack free polyurethane elastomer within approximately four hours. It is intended for use with SBS modified bitumen, APP granule surfaced and BUR roofing systems. Application is recommended for vertical surfaces such as flashing walls and curbs, penetrations, roof drains, penetration pockets with pipe clusters and unusual shaped penetrations. UltraFlash Liquid Flashing adheres to concrete, steel, glass, wood and most surfaces. Mixing the UltraFlash Liquid Flashing can be done in the original 19 litre (5 gallon) containers for 3 minutes. For those who prefer a method other than mixing, UltraFlash Liquid Flashing Dual Cartridges are also available. These cartridges contain the two component adhesive and require the use of an applicator and static mixer. Uses Ultraflash Liquid Flashing is specifically formulated for use with all bituminous systems, including hybrid systems. It is excellent for use in projects such as: New and re-roof Metal roofing Paver systems Historic preservation and / or restoration Features Low permeability Wide application temperature range Low cost per penetration Minimal odour release Great tensile strength Enhanced workability Great crack bridging capabilities Property Test Method Value Colour Visual Black Tensile Strength ASTM D 412 4.1 MPa (600 psi) Elongation ASTM D 412 > 300% Permeability to Water Vapour ASTM E 96 Method E, 38°C (100°F), 2.5 mm (100 mil) sheet .03 Perms Hardness ASTM D 2240 @ 25°C (77°F) 65 Shore A Working Time* @ 25°C (75°F) 30 Minutes Rainproof After* @ 25°C (75°F) 4 Hours Crack Bridging After Heat Aging 3 mm (1⁄8") Softening Point, Ring & Ball ASTM D 36 @ 135°C (275°F) Elastomeric Waterproofing ASTM C 836, ASTM C 957 Exceeds All Criteria Abrasion Resistance ASTM D 4060, 1000 gr. / 1000 rev.
