Abstract
Carboxylic acid salts of tertiary amines for use as an accelerator for an anhydride based epoxy curing agents are disclosed. The disclosed carboxylic acid salts of certain tertiary amines are latent anhydride accelerators and enable epoxy resin curing when heated to an elevated temperature (e.g., an onset temperature of greater than about 50° C.).
