Even in Central Florida we have some cool Winter
days, especially in the early morning hours. The
published set and cure times for Aerospace Grade Epoxies
like Aeropoxy and Vpoxy are based on 77°F.
hand mixed batch (no nozzle), work on scraps of card
stock and apply some external warmth with a modeling
heat gun. This accelerates the exothermic chemical
the epoxy is applied with a mix nozzle, warm the glue
joint with the heat gun set on "low" power to get things
going. Multiple flashes with the heat gun (on low) while
the glue is progressing will reduce the total set and
cure time. Just be careful to not damage the
composite structure and paint with too much heat.
We prefer to not mix epoxies in wax coated paper cups,
especially if external heat is going to be applied.
