摘要： The present disclosure provides a method for bonding parts, comprising the following steps
(a) Providing a two-component adhesive composition precursor, comprising Part (A) comprising at least one first dye and at least one epoxy curing agent;
Part (B) at least one second dye different from first dye and at least one epoxy resin;
(b) Mixing part (A) and part (B) of the two-component adhesive composition precursor to obtain an adhesive composition;
(c) Applying the adhesive composition onto a first part;
(d) Applying a second part onto the adhesive composition applied to the first part;
(e) Perform a first curing step at a first temperature, wherein the adhesive composition undergoes a first colour change;
Perform a second curing step at a second temperature higher than the first temperature, thereby fully curing the adhesive composition so as to obtain a structural adhesive bond between the first and second parts, wherein the adhesive composition undergoes a second colour change.

摘要： 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; iii. a metal nitrate catalyst; iv. optionally, a metal triflate catalyst; and b) a part (B) comprising: i. an epoxy resin; ii. a filler material; iii. an epoxy-based reactive diluent; and iv. optionally, a core-shell polymer toughening agent; and wherein the amount of filler material is selected such as to provide the part (B) with a hysteresis area of at least 30 Pa x 1/s, when measured at 23°C according to the test method described in the experimental section. The compositions of the present disclosure are particularly suitable for use in structural bonding applications, in particular for adhesively bonding small parts in manufacturing operations in aeronautic and aerospace industries. The present disclosure also relates to method of using such epoxy resin based curable compositions.
