How to Measure and Mix Epoxy Resin
What you will need:
• Set of digital scales OR calibrated mixing cups
• x2 clean mixing pots
• x2 clean mixing sticks
• Nitrile gloves/safety glasses and other PPE as required
• Optional: Heat gun or blow torch
GlassCast 3 is a two-part epoxy resin system. As soon as the two
parts are mixed together they will begin to cure. It is essential to
mix the resin and hardener exactly at the correct mix ratio. Failure
to do so will result in a poor or only partial cure of the resin. Under
no circumstances add ‘extra hardener’ in an attempt to speed up
the cure time; epoxies do not work in this way.
Mixing by Weight
100:50 (2:1) Resin:Hardener
Use digital scales to accurately weigh the correct amount of
resin into a cup, re-zero the scales and then weigh in the correct
amount of hardener. Try to be as accurate to within 1 -2 grams,
particularly on smaller mixes.
