摘要
A fluorocarbon additive that may be added to any resinous composition including aqueous and solvent based paints and coatings to improve the soil resistance and stain release characteristics of the composition. The additive is a mixture of discrete non-polymeric oligomers with each oligomer comprising a central core molecule having one or more fluorocarbon chains extending from and bound to the oligomer core by a mainly covalent bond, and having one or more non-fluorinated appendages extending from the core. In a preferred embodiment, the inventive oligomer is comprised of a polyfunctional core molecule having two or more functional groups, wherein a fluorocarbon chain is covalently bound to less than all of the functional groups. Particularly useful polyfunctional core molecules are selected from the group of tri-aziridines, trimers of isocyanates and/or tri-epoxy systems.
