ASI 57

Hybrid Performance Sealant

ASI 57 Hybrid Performance Sealant is a one-part, polyether sealant that uses ASI’s innovative hybrid technology to produce a material with many of the same characteristics of silicones and polyurethanes but with better performing properties. Unlike many polyurethanes ASI 57 contains no solvents or isocyanates which makes it VOC compliant. Due to the formulation, ASI 57 is able to cure when moisture is present without outgassing which makes it ideal for wet or dry climates. ASI 57 is a non-slump sealant and can be applied to vertical or overhead surfaces without flowing or sagging. ASI 57 has excellent movement capabilities and over 300% elongation. It is extremely resistant to weathering and UV degradation. ASI 57 is 100% solids and has a very low odor which makes it ideal for confined or occupied work spaces. ASI 57 is a paintable, non-staining hybrid sealant with a very broad adhesion profile.


Cured ASI 57 Hybrid Performance Sealant may be painted with most industrial and consumer paints.

Storage Life

Nine months in unopened containers at temperatures not exceeding 80°F.


Use ASI 57 Hybrid Performance Sealant with adequate ventilation. Inhalation of vapors during application and cure may cause slight eye or throat irritation. In case of contact with eyes, lips or mouth, flush thoroughly with water. If irritation persists, consult a physician. Avoid repeated, prolonged contact with skin. See SDS for additional information. Keep out of reach of children.
