Description
American Sealants ASI 5900 Fast Grab Hybrid Adhesive delivers powerful, immediate green strength using advanced hybrid polymer technology. This one-part adhesive bonds instantly to a wide range of substrates, providing long-term durability without shrinking, bubbling, or outgassing. Free of solvents and isocyanates, ASI 5900 is VOC compliant and user-friendly across temperature extremes.
Perfect for construction, transportation, and manufacturing applications, ASI 5900 maintains its consistency from 0°F to 150°F and can even bond to damp or wet surfaces without loss of adhesion.
