  • Publication number: 20130109784
    Abstract: The invention relates to aqueous radiation-hardenable epoxy acrylate dispersions comprising (a) an epoxy acrylate resin (P*) with at least two acrylate groups per molecule, wherein at 25 degrees Celsius, said epoxy acrylate resin is not self-disperging in water; and (b) a dispergator (D*) with at least one acrylate group per molecule, wherein said dispersions can be produced by converting, in a first step (i), in the presence of a catalyst if need be, one or several compounds (A) selected from the group of non-ionic compounds having a HLB value of less than 12, and containing at least two oxirane groups per molecule, with one or several compounds (B) selected from the group of non-ionic compounds having a HLB value in the range from 12 to 20, and which contain at least one h-acid group (ZH) per molecule. The compounds (A) and (B) are employed at an equivalence ratio EpO (A):ZH (B) in the range from 1.

  • Publication number: 20120059081
    Abstract: The invention relates to resins comprising acrylate groups that are liquid at 25° C., obtained in that polycarboxylic acids (a) comprising at least 2 carboxyl groups and at least 2 C atoms per molecule are converted in a first stage with polyamines (b) comprising at least 2 amino groups and at least 2 C atoms per molecule, such that an intermediate compound (z) results, said compound being terminated by carboxyl groups, and said compound (z) being functionalized in a second stage, such that the free carboxyl groups thereof are provided with one or more (meth)acrylate groups in one or more stages, said resins being suitable as radiation-curing compounds for producing coatings.

  • Publication number: 20090099278
    Abstract: Radiation-curable acrylated polyaminoamides obtainable by Michael addition of polyaminoamides containing terminal amine groups (A) and polyolester acrylates (B), the molar ratio of the acrylate groups in the polyolester acrylates (B) to the aminohydrogen groups in the polyaminoamides (A) being at least 1:1, characterized in that the polyaminoamides have an amine value above 115, are suitable as radiation-curable compounds for the production of coatings.
