6422
Astro 6422 is a versatile two-part epoxy adhesive formulated for high mechanical strength, excellent adhesion, and resistance to elevated temperatures. It is slightly thixotropic, exhibits low shrinkage, and generates minimal exotherm during cure. The material is 0-VOC and free of CMR substances (carcinogenic, mutagenic, or toxic for reproduction).
Supplied in convenient 2:1 ratio cartridges for easy dispensing, Astro 6422 is suitable for use as a hardware adhesive for locking end-wedges, bolts, and similar components. It also performs well as a general-purpose structural adhesive across a range of applications.
