In Reply to: Mixing different brands of epoxy/hardener posted by Page on November 15, 2002 at 10:25:45:
from my experience with epoxy resins and hardener,
resins are very common and similar no matter what brand. all u need to know is the EEW (epoxy equivalent weight)of the resin and AHEW (Amine Hydrogen Equivalent Weight)of the hardener regardless of it's chemical type. Most common bisphenol A epoxy resin's EEW is 180 to 190.
Amount of hardener to 100 part of resin=AHEW divide EEW then multiply by 100.
the characteristic, pot life and curing time of the mixture is dependant on the hardener. so, ask the supplier for specification before buying the hardener. and its advisable to tried with small scale first.
hope this help ;)
good luck
