Epoxy Cure Time
Name: Naomi W.
Why does epoxy glue take less time to harden when in the
sun and if i wanted to do an experiment on this, what apparatis would I need?
The curing time of some epoxies is affected by ultraviolet (UV) light.
a source of ultraviolet light. You might like to ask your dentist about those
materials because UV curing resins are used in modern dentistry.
In addition, epoxy curing time is affected by temperature . The warmer the
faster the cure. It's likely that the sunlight warmed the mixture. It will be
tricky proving this with a thermometer because the thermometer will become
in the hardened resin. Perhaps you could make small batches of the mix and
into a soda bottle cap that's sitting in a small dish of water. You could
thermometer into the water next to the cap. Be sure to cover the cap so
strike the mixture. Otherwise you won't know whether it's the heat or
light that is
affecting the cure time.
Good luck with your experiment.
