Abstract

The present disclosure is directed to a precursor composition for a curable adhesive, the precursor comprising: a) a part (A) comprising: i. a first epoxy curing agent comprising at least one polyether amine and having an amine equivalent weight of at least 45 grams per mole of amine equivalents; ii. a second epoxy curing agent distinct from the first epoxy curing agent or a secondary curative; iii. a metal nitrate catalyst; iv. optionally, a metal triflate catalyst; and b) a part (B) comprising: i. a multifunctional first epoxy resin having at least three functional groups; ii. a second epoxy resin distinct from the first epoxy resin; iii. a core-shell polymer toughening agent iv. a filler material; and v. optionally, an epoxy-based reactive diluent. The compositions of the present disclosure are particularly suitable for use in structural bonding applications, in particular for adhesively bonding parts in manufacturing operations in aeronautic and aerospace industries. The present disclosure also relates to method of using such epoxy resin based curable compositions.
