| 摘要 |
The invention features a polyamine epoxide adduct, prepared by admixing a source of epoxy group with a polyamine, and allowing the epoxy groups to rea ct with the terminal amino groups of the polyamine so as to form the polyamine epoxy adduct. The polyamine epoxide adduct of the invention can be used as a component for preparing a polyurea polymer, thereby providing the resulting polyurea polymer with improved adhesiveness and greater chemical resistance to acidic conditions. Polyurea polymer coatings prepared from polyamine epoxide adducts demonstrate better chemical resistance and adhesion when applied to substrates than do conventionally prepared polyurea formulations.
