Ikke-ioniske, lateralt stabilisert polyuretanharpiks, et beleggspreparat inneholdende harpiksen samt beleggspreparatets anvendelse i fler-sjiktspreparater

摘要

This invention, therefore, relates to the field of polyurethane coatings for use in automobile basecoat/clearcoat systems. In particular, this invention relates to water-dispersible polyurethane resins having polyether sidechains which may be utilized in basecoat compositions as principal resins or grind resins. These polyurethane resins may be laterally stabilized or terminally stabilized. The terminally stabilized resins of this invention are preferably employed as principal resins in basecoat compositions.
