Abstract
PURPOSE: An epoxy resin whose curing time, transparency and cure shrinkage are improved, by adding an acid anhydride curing agent and a cure accelerator comprising a quat. ammonium salt to an epoxy resin.
CONSTITUTION: To a composition comprising an epoxy resin and a curing agent comprising an acid anhydride is added, as a cure accelerator, a quat. ammonium salt represented by the formula wherein R1 is a C1W3 alkyl, R2 is a C1W3 alkyl or benzyl, R3 is a C1W3 alkyl, -CH2-CH(OH)-R5 in which R5 is of C10W28, R4 is a C10W28 alkyl, X is a halogen or OH. Examples of the quat. ammonium salt include trimethyl-2-hydroxy-4,6-diethyloctylammonium hydroxide and triethyl-4,6-diethyloctylammonium chloride.
