REFLECTOR: Epoxy Ratio Pump Box

[Andy Millin]

Jorge,

If I had it to do over again, I would have made mine considerably
bigger.  I would have liked to have it about 2'x4'.  It is primarily
used for keeping the resin warm but can come in very handy to use as a
cure/post cure autoclave.  When lay-ups will fit, I bake them in my
warmer over night.

Also, I had my EZ-84 hardener go bad.  The factory ships about 2 1/2
gallons with the kit.  It doesn't like light and it doesn't like to
breath.  If you let it, the styrene will evaporate.  It will slowly go
from the green-yellow thin syrup to something that is as dark as
molasses and pours like it too.  When it does the epoxy cures brittle
and adheres poorly.  For that reason I only keep my resin in the warmer.
The hardener seems to last longer.

Just a thought or theory on the hardener.  The plastic bucket it came in
might have allowed the styrene to dissipate.  If I had it to do again I
might put it in an opaque container like a sealed paint can.  If it was
sealed tightly enough, I might even keep it in the refrigerator until I
needed it.  The epoxy and hardener aren't terribly expensive from the
factory.  What will kill you is the shipping.  I think it was $57 for
1/2 gallon of hardener to be delivered to my door.

FWIW,

Andy

Can someone suggest convenient dimensions for an insulated box to keep
the epoxy warm in the Michael's Epoxy Ratio Pump Box? Thanks,
