Solvent Compatibility Resistance to solvents is measured by observing, measuring and weighing cured resin cubes before and after soaking in the solvent for 24 h. SOLVENT Butyl acetate Diethyl glycol monomethyl ether Isopropyl alcohol LEGEND A = Accetaptable resistance1 U = Unacceptable resistance2 Acceptable is defined as a resin cube having no visible change in appearance, < 0.5% increase in width, and < 1% weight gain after a 24 h solvent soak 2 Unacceptable is defined as a resin having one or more of: visible change in cube, ≥ 0.5% increase in width, or ≥ 1% weight gain after a 24 h solvent soak
