Superior protection from water damage
• 100% butyl sealant provides excellent adhesion to most
common building materials
• Meets the AAMA 711-13 material standard at the highest
classification levels: Class A (no primer) and Level 3
Thermal Exposure (80°C / 176°F for 7 days)
• Meets and Exceeds ASTM E331 Standard Test Method
for Water Penetration of Exterior Windows, Skylights,
Doors, and Curtain Walls by Uniform Static Air Pressure
Difference: no leakage at 300 Pa (equivalent to 50 mph
windload), even after thermal aging (0-120°F)
• Does not contain asphaltic / bitumen adhesive materials
which many window manufacturers prohibit due to
adverse material reactions, such as black staining, oozing,
and deformation over time, particularly with vinyl flanges.
• Can be installed at external temperatures as low as -4°C
(25°F) as long as the surface is clean and free from frost
and ice
