FIELD: special compositions.
SUBSTANCE: invention relates to a method for preparing an aqueous bicomponent joining composition as a cover or adhesive for different backings, such as aluminum, steel, galvanic steel, copper, zinc, magnesium and their alloys, and can be used in automobile industry for external finishing large means of transportations. The composition comprises an aqueous dispersion of at least partially neutralized polymer representing a derivative of amino-functional epoxide and organic compound comprising at least two acetoacetate groups or acetoacetamide groups or combination of two groups. Invention provides preparing covers showing high polish, good waterproofing and resistance to solvents, high hardness and adhesives of high adhesive strength.
EFFECT: improved and valuable properties of composition.
