ASI 57 is a one-part, moisture-cure Class 50 hybrid sealant and adhesive with 50% joint movement capability for industrial and construction applications where high flexibility, UV resistance, and wet-substrate bonding are required. Available in Black 10.2 oz cartridges.
Performance in Production
- 50% joint movement capability covers applications where standard Class 25 sealants are insufficient.
- 600% elongation at break supports bonding on substrates subject to significant flex, vibration, or movement.
- Non-slump consistency holds position on vertical and overhead surfaces without repositioning.
- Cures to wet substrates without bubbling or outgassing, and withstands immediate rain after application.
- 100% solids formulation does not shrink during cure.
- UV-resistant formulation does not yellow, chalk, or degrade with long-term outdoor exposure.
- Contains no solvents or isocyanates. Low odor supports use in occupied or enclosed spaces.
- Paintable within 24 hours using most consumer and industrial latex paints.
- MEKO-free. Compatible with electronics per manufacturer documentation.
- Allow 7 days for maximum strength before testing. Lower temperatures and humidity slow skin and cure times.
- Surfaces should be clean before application. IPA or acetone recommended for surface prep; do not use petroleum-based solvents. Priming is not normally required.
- Do not use on polyethylene, polypropylene, or TPO without prior testing.
