Abstract
The present invention relates to novel low-monomer-content, low-viscosity, high-activity preparations made of isocyanurates containing isocyanate groups and of phthalate-free plasticizers, to use of the same as adhesion promoters with improved adhesion for coating compositions based on plasticized polyvinyl chloride, and also to coatings and coated substrates.
