Its non-hardening characteristic makes it particularly suited for shielding joints and seams which are likely to be disassembled or applications where vibration and thermal shock resilience is required. Minimum recommended bond line for CHO-BOND 4660 is 0.015 inches (0.18 mm).

CHO-BOND 4660 dries to touch in minutes and develops its final material properties in 168 hours. The compound remains permanently flexible and adherent with no tendency to crack or pull away from the substrate. Some surface crusting may be experienced, but CHO-BOND 4660 will remain pliable below the surface. In addition, CHO-BOND 4660 may be used to help seal against gases as the polyisobutlyene polymer system has excellent impermeability properties.


It is designed for use as a fillet, gap filler and seam sealant on electrical enclosures for EMI shielding or electrical grounding.
