FIELD: chemistry.
SUBSTANCE: invention relates to a composition which is suitable as an adhesion promoter for a coating agent based on plasticised polyvinyl chloride. The disclosed composition contains A) 15-50 wt % isocyanate group-containing isocyanurates and B) 50-85 wt % n- or isoalkyl monobenzoates, wherein i) the isocyanate group-containing isocyanurate is obtained via trimerisation of a mixture of 2,4-diisocyanatotoluene and 2,6-diisocyanatotoluene and ii) the sum of all weight percentages is 100%. The invention also relates to a method of producing said composition, use thereof as an adhesion promoter for a coating agent based on plasticised polyvinyl chloride and to a coating agent.
EFFECT: disclosed composition has good adhesion properties and does not contain phthalates which are hazardous for humans and bioaccumulative.
