Acetone Discoloration of Epoxy Reaction-Mixture

Abstract

To determine the involvement of acetone in the discoloration of cured epoxy polymer, epoxy reaction-mixture was combined with different concentrations of acetone before being allowed to cure at either one atmosphere or full vacuum. Acetone was found to have a direct impact on the degree of discoloration of cured epoxy reaction-mixture. Curing the epoxy reaction- mixture under vacuum decreased discoloration caused by the acetone.
