The invention relates to epoxide-amine adducts obtainable by reaction of one or more primary amines (A) of general formula (I)Q-NH&#x2003;&#x2003;(I)with one or more monoepoxides (B) of general formula (II) wherein Q is a radical R-[OEt][OPr][OBu]-, in which Ris a radical selected from alkyl radicals having 1 to 6 carbon atoms, OEt is an ethylene oxide radical, OPr is a propylene oxide radical and OBu is a butylene oxide radical, n is a number from 0 to 100, m is a number from 3 to 50 and s is a number from 0 to 20 and n+m+s=3 to 170, R is an organic radical selected from aliphatic radicals having 4 to 24 carbon atoms, aromatic radicals having 6 to 18 carbon atoms and araliphatic radicals having 7 to 34 carbon atoms, and p is 0 or 1, wherein (i) the primary amine(s) (A) and the monoepoxide(s) (B) are reacted in an equivalents ratio (A):(B) of from 1:2 to 1:1.35; and (ii) at least 40 mol % of the radicals R are selected from aromatic radicals having 6 to 18 carbon atoms and araliphatic radicals having 7 to 24 carbon atoms; and optionally subsequent salification and/or quaternization and/or modification of the reaction product. The invention furthermore relates to wetting agents and dispersants comprising or consisting of the epoxide-amine adducts and also to the production of the wetting agents and dispersants and to the use of the epoxide-amine adducts and the wetting agents and dispersants for the production of dispersions. The invention also relates to dispersions and particle formulations comprising the epoxide-amine adducts and wetting agents and dispersants.

Monoepoxide-monoamine adducts as wetting agents and dispersants

The invention relates to the use of a branched polyester having an average of at least 2.8 terminal groups as additive for a curable pre-polymer composition, wherein the branched polyester acts as de-foaming agent.

Use of a branched polyester

The invention relates to a composite formulation comprising a specific mediator additive component (A) of relatively high molecular weight, a filler component (B) and a binder component (C). The composite formulation can be cured to a composite which is especially suitable for the production of moldings.

Curable polymer mixture

The invention relates to a use of at least one condensation product (A) in the form of the free compound or in the form of a salt of at least one acid as a thixotropy-increasing additive, which condensation product can be obtained by reacting at least one polymerized fatty acid or at least one reaction product (U) of at least two polymerized fatty acids and at least one polyamine having at least two primary amino groups as component (a1) with at least one polyalkylene polyamine, which is capable of forming at least one imidazoline and/or tetrahydropyrimidine unit and which has at least two primary amino groups or at least one primary and at least one secondary amino group, a composition containing at least one such condensation product (A) and at least one thixotropic agent (B), and a use of said composition, which additionally comprises at least one binder (C), as an adhesive, sealant, paint, coating agent, adhesive resin, casting resin, artificial marble, floor covering, polymer concrete, or fiber composite material.
