AU-1 commercial window sealant is unlike other installation products on the market. This single-component sealant uses state-of-the-art ingredients, including Aqueous Polyurethane Dispersion (PUD), to create a high-performance, gun-grade product. AU-1’s Acrylic Urethane technology offers better adhesion and durability to some of the most popular window sealant technologies, including polyurethane, silicone, and solvent based formulations.

As an elastomeric urethane acrylic sealant, AU-1 is internally plasticized. The composition of this sealant makes it easy to apply, tool, and clean up, saving operations time and money in the process. The internally plasticized composition means no plasticizers are involved in the formula, so no plasticizers can leach out from the product. This fact allows AU-1 to maintain high elasticity and adhesion across all climates, gives superior paintability, and it’s more eco-friendly than polyurethane and other sealants.

Once applied, AU-1 creates an airtight and water-resistant seal for superior protection against environmental conditions. AU-1 sealant for window installation is resistant to UV exposure and will not discolor over time. Regardless of the weather, AU-1 lasts.
