Precautions:
Almost all formulated epoxy and urethane materials contain at least some volatile ingredients. These ingredients are an essential part of the product and will start flashing off under vacuum. This is evidenced by the fact that the mix being de-aired never seems to be totally free of bubbles no matter how long it is vacuumed. Care should be taken not to vacuum strip the material. In most cases vacuum at 29” Hg for 5-10 minutes will sufficiently de-gas the mixture.
