Description
The American Sealants ASI 5900 Fast Grab Hybrid Adhesive (20 oz Unipac) provides the same reliable performance as the cartridge version—now in a larger, production-friendly format. Formulated with ASI’s hybrid technology, ASI 5900 delivers immediate tack, high green strength, and long-term durability without shrinkage or solvent off-gassing.
This one-component, non-sag adhesive bonds securely to metals, plastics, composites, and porous surfaces, even when moisture is present. Its fast-grab formula minimizes clamping, supports overhead use, and remains easy to apply from cold to hot climates.
