Which should you choose for cure time?

  • - Both products list the same baseline full cure time of 24h, so temperature and humidity may be the deciding factors.
  • - Epoxy Weld Bonding Compound allows the lower minimum application temperature (39°F).
  • - Gorilla Glue Original Polyurethane Adhesive gives more working time before assembly pressure or tooling becomes urgent.
  • - Watch for amine blush risk in humid epoxy work.

Gorilla Glue Original Polyurethane Adhesive has a 24h full cure time with a 10-minute open time.

Epoxy Weld Bonding Compound has a 24h full cure time with a 6-minute open time. Watch for amine blush in humid conditions.
