POLYASPARTIC COATING COMPOSITION, COATING FILM, AND COATED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2018/163953
Kind Code:
A1
Abstract:
Provided is a polyaspartic coating composition which contains: an aspartic acid ester compound; and a polyisocyanate composition containing polyisocyanate obtained from one or two or more diisocyanate monomers selected from the group consisting of aliphatic and/or alicyclic diisocyanates, wherein the molar ratio x represented by equation (1) is 0.05-0.5, the molar ratio d represented by equation (4) is 0.02-0.5, and the molar ratio e represented by equation (5) is 0-0.05. (1) molar ratio x=(B+C+D)/(A+B+C+D), (4) molar ratio d=D/(A+B+C+D), and (5) molar ratio e=E/A. In these equations, A represents the content of an isocyanurate group, B represents the content of an iminooxadiazinedione group, C represents the content of a uretdione group (mol%), D represents the content of an allophanate group (mol%), and E represents the content of a biuret group (mol%) in the polyisocyanate composition.
