AU-1 COMMERCIAL CONSTRUCTION SEALANT
Premium-Grade, High-Performance, High-Movement, Single-Component, Elastomeric, Acrylic Urethane Sealant
AU-1 is a highly elastic, non-sagging, high-performance construction sealant with extreme resistance to aging. Uniquely formulated from state-of-the-art ingredients, including Aqueous Polyurethane Dispersion (PUD), which makes it an ideal sealant for commercial and industrial applications. AU-1 requires no mixing or priming to bond at the molecular level to most construction materials. AU-1 is paintable and will never bleed through the paint finish or create tacky surfaces, making it resistant to dirt pickup. Once cured AU-1 is exceptionally resistant to mold and mildew. AU-1 has outstanding UV resistance and maintains high elasticity and adhesion in all climates even after years of exposure. It is VOC compliant nationwide including all CARB and SCAQMD requirements. AU-1 does not lose elasticity under dynamic mechanical stress.
A single component, modified acrylic urethane, AU-1 is a premium sealant that is high-performance and designed for high-movement. This construction sealant is free of plasticizers and more eco-friendly than other products on the market. Every AU-1 construction sealant cartridge is air vacuum filled to prevent any air pockets and handled with the utmost quality assurance.

- ASTM C-920 Class 25
