    Abstract: The use of special condensation prods. (I) as emulsifiers for the prodn. of aq. epoxy resin systems is claimed. These emulsifiers indicate the end of the working time by a sharp increase in viscosity. (I) are condensation prods. of (A) an aliphatic polyol component with a wt.-average mol. wt. (Mw) of 200-20,000, at least 5 wt% of which has a Mw of at least 4000 and (B) an epoxide component contg. at least one epoxide cpd. with at least 2 epoxide gps. and an epoxide gp. content of 500-10,000 mmoles/kg. Also claimed are epoxy resin dispersions contg. (I) and amine hardeners (II) in amts. such that the no. of epoxide gps. z(EP) and the no. of amine H atoms z(H) are in a ratio of (1:0.75)-(1:2.0).

    Abstract: Polyol-epoxide addition products obtained by reacting (A) an aliphatic polyol having a weight average molecular weight (Mw) of from 200 to 20,000 g/mol and (B) an epoxide compound containing at least two epoxide groups per molecule and having an epoxide equivalent weight of from 100 to 2,000 g/mol, where the ratio between the number of equivalents of OH groups and the number of equivalents of EP groups is from 1:3.6 to 1:10, preferably from 1:4 to 1:9, particularly preferably from 1:4.5 to 1:8, and the epoxide equivalent weight of the addition product is between 150 g/mol and at least 8,000 g/mol, preferably between 250 g/mol and 1,000 g/mol. These addition products are used as nonionic emulsifiers in water-dilutable liquid epoxy resins.

    Abstract: 1. Aqueous epoxy resin dispersions containing (A) an epoxy resin which is a product of the condensation of (A-1) from 50 to 95 % by weight, preferably from 55 to 85 % by weight, of one or more epoxide compound(s) containing at least two epoxide groups per molecule and having an epoxide equivalent weight of from 100 to 2000 g/mol, (A-2) from 5 to 50 % by weight, preferably from 15 to 45 % by weight, of an aromatic polyol and (A-3) from 0 to 25 % by weight, preferably from 0 to 10 % by weight, of modifying compounds containing at least two epoxide reactive groups, (B) a dispersant comprising (B-1) a product of the condensation of a polyol having an average molecular weight of (Mw) of from 200 to 20,000 g/mol and an epoxide compound containing on average at least two epoxide groups per molecule and having an epoxide equivalent weight of from 100 to 10,000 g/mol and (B-2) optionally further, preferably nonionic surfactants, (C) the polymer, prepared in this dispersion, of ethylenically unsaturated monomers capable of free-radical polymerisation or copolymerisation, (D) a curing agent for the epoxy resin (A) and (E) optionally conventional additives and catalysts. These aqueous epoxy resin dispersions are suitable for the production of coatings, in particular for the internal coatings of beverage cans and preserve cans.

These aqueous epoxy resin dispersions are suitable for the production of coatings, in particular for interior coatings of cans for beverages and preserves.
