US Classification:

522/084000, 427/558000

Abstract:

The present invention is directed to a waterborne, UV-curable polyurethane emulsion and the use thereof in producing soft touch coatings. The emulsion is prepared by a) reacting specified hydroxy-functional components with di- and/or polyisocyanates, b) forming a dispersion of the resultant product with water and reacting the dispersion with amine functional materials.

Appl. No.:

11/096590

Inventors:

Richard Roesler - Wexford PA, US
Carol Kinney - Eighty Four PA, US
Aaron Lockhart - Pittsburgh PA, US
James Garrett - McKees Rocks PA, US

International Classification:

C08G 18/00

US Classification:

528044000

Abstract:

The present invention is directed to a polyisocyanate mixture i) having an NCO content of 5 to 35% by weight and a monomeric diisocyanate content of less than 3% by weight, and prepared from a polyisocyanate adduct, ii) containing allophanate groups in an amount such that there are more equivalents of allophanate groups than urethane groups and such that the polyisocyanate mixture remains stable and homogeneous in storage for 1 month at 25 C. and iii) containing siloxane groups (calculated as SiO, MW 44) in an amount of 0.002 to 50% by weight, wherein the preceding percentages are based on the solids content of the polyisocyanate mixture and wherein the siloxane groups are incorporated by reacting an isocyanate group with a compound containing one or more hydroxyl groups directly attached to a carbon atom and one or more siloxane groups. The present invention is also directed to a process for the production of this polyisocyanate mixture and to its use, optionally in blocked form, as an isocyanate component in one- or two-component coating compositions.

Abstract:

The present invention is directed to a polyisocyanate mixture i) having a monomeric diisocyanate content of less than 3% by weight, ii) having a urethane group content of more than 50 equivalent %, based on the total equivalents of urethane and allophanate groups, and iii) containing siloxane groups (calculated as SiO, MW 44) in an amount of 0.002 to 50% by weight, wherein the preceding percentages are based on the solids content of the polyisocyanate mixture and wherein the siloxane groups are incorporated by reacting a) an isocyanate group from a polyisocyanate adduct containing isocyanurate groups and prepared from a monomeric diisocyanate having at least one cycloaliphatic group with b) a compound containing one or more hydroxyl groups directly attached to a carbon atom and one or more siloxane groups to form urethane groups. The present invention also relates to the use of this polyisocyanate mixture, optionally in blocked form, as an isocyanate component in one- or two-component coating compositions.
