AU-1 Commercial Construction Sealant is a highly elastic and extremely non-ageing high-performance construction sealant. It is an aqueous-based urethane acrylic polymer and one of the first high performance sealants of its’ kind for the commercial building industry. The active ingredient in AU-1 is an Aqueous Polyurethane Dispersion.

As internally plasticized resin it requires no mixing or priming to bond molecularly to most construction materials. AU-1 is paintable with no shine through or plasticizer bleed. It has very low VOC content meeting CARB and SCAQMD requirements. AU-1 is extremely UV resistant and maintains high elasticity in all climates. It maintains its adhesive force even after years of exposure by bonding to surfaces through crosslinking on a molecular level. Once cured has exceptional mold and mildew resistance. AU-1 can be used with confidence in all weather conditions and it does not lose its elasticity under constant, greatly varying mechanical stress.

  • Ready to use, no mixing, reduces prep time
  • No primer required for most substrates reducing application time
  • Easy to gun and tool, for quicker application and neater joints
  • Seals joints up to 2” with proper joint design
  • Exceptional resistance to aging and weathering for long term durability
  • Available in sausages for less jobsite waste and lower disposal costs
  • Can be painted and can be tinted with standard latex paint
  • Superior adhesion to construction materials over long periods of time
  • Meets VOC requirements for all 50 states
  • Joint movement capacity ±25% with 800% elongation providing excellent flexibility for moving joints
