摘要:
The invention relates to alkoxylated epoxide-amine adducts having a number-average molecular weight of more than 500 g/mol, which are preparable by reacting A) mono- and/or polyepoxides having at least 8 carbon atoms with B) primary and/or secondary amines and/or primary and/or secondary alkanolamines and/or secondary alkylalkanolamines, to form an adduct having one or more secondary OH groups, and subsequently alkoxylating the adduct with C) alkylene oxides. The invention also relates to a process for preparing the alkoxylated epoxide-amine adducts and to their use as wetting agents and dispersants for organic and inorganic pigments and fillers. The invention relates further to powderous or fibrous solids coated with the alkoxylated epoxide-amine adducts.

摘要:
The invention relates to a cladding resin composition curable by heat, ultraviolet radiation, an electron beam or the like. The composition comprises a polyoxyalkylene polyol phosphate ester (hydroxyl value: 10-2,000 mg KOH/g) and a polymerizable or reactive functional group-containing compound. This composition is highly conductive as it is and, without incorporation of the conventional conductive additives, can be used successfully in the field of coatings and protective films where electric conductivity is a requisite.
