    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.

    摘要： The invention relates to a method for gluing two substrates together, wherein one substrate is coated with a layer of an aqueous adhesive containing dispersions from chlorinated polyolefins and additives having a pH of 10 to 13. An activator solution is applied to the first or second substrate in a subsequent step, wherein the activator solution contains substances comprising acid groups, and gluing the coated surfaces together using light pressure. The invention describes a 2-part adhesive consisting of a storage-stable aqueous adhesive dispersion containing 25 to 50% by weight chlorinated polyolefins, 5 to 30% by weight additional polymers, and additives and water having a pH value of 9 to 13 and an activator solution as a second component, wherein the activator solution contains carboxylic acids, sulfonic acids, phosphonic acids, polymers comprising carboxylic acid or sulfonic acid groups, inorganic acid salts or Lewis acids, and water or organic solvents.
