COMPOSICION ENDURECIBLE POR ACCION DE HUMEDAD

LA COMPOSICION ENDURECIBLE POR LA ACCION DE LA HUMEDAD CONTIENE: A) UNO O VARIOS COMPUESTOS EPISULFURO QUE PRESENTAN EN PROMEDIO MAS DE UN GRUPO 1,2-EPITIOPROPILETER DE FORMULA I POR MOLECULA, Y B) UNA O MAS DICETIMINAS ALIFATICAS N,N''-DIALQUILSUSTITUIDAS DE FORMULA GENERAL (II). A moisture curable composition contains: (a) one or more episulfide compounds having on the average more than one 1,2-epithiopropyl ether group of the formula I (I) per molecule, and (b) one or more aliphatic N,N'-dialkyl-substituted diketimines of the general formula II (II) wherein A is a divalent aliphatic, cycloaliphatic or arylaliphatic group, and R1 and R2 are each an alkyl group, or form together with the C-atom, to which they are bonded, a cycloalkyl group or cycloalkenyl group, and (c) at least one component, selected from the group of the setting accelerators as well as commercially available solvents, reactive diluents, plasticizers, thixotropic aids, fillers and pigments. This composition may be used as lacquers, paints and coatings for steel and concrete. There is also described a process for the preparation of 1,2-epithiopropyl ethers.
