Bubble free steel epoxy dies in hydraulic metal forming
I have found it difficult to get consistent results using “Devcon
Steel Epoxy”. I also found the product to be too expensive along
with the bubbles created.
I have started to use iron powder mixed with "Devcon Two Ton Epoxy"
and find that the bubbles persist. I’ve tried using a vibrator
(vibratory polisher), on the epoxy separately and mixed with the
iron powder. I’ve also tried adding 5% acetone as advised by Devcon
with poor results. The opportunity to do anything is severly limited
by the fast cure rate of the mix. Because of the extremely thick
consistincy and the fast cure rate I cannot imagine the vacum
machine being effective.
I would apprectiate any suggestions on bubble elimination.
