Abstract: Provided are two-part shimming adhesives comprising a base part and a hardener part that are curable upon mixing. The base part includes a multifunctional epoxy resin having an epoxide functionality of at least three, a difunctional epoxy resin miscibly blended with the multifunctional epoxy resin. The hardener part includes a polyetheramine. Either the base part or hardener part further comprises an inorganic filler present in an amount from 10 percent to 60 percent, relative to the overall weight of the two-part curable shimming adhesive, and a phosphoric acid ester. The shimming adhesive enables joints to be assembled in one step, providing a significant advantage to the user.
