Abstract

Polyurethane prepolymers having non-linear short chain diols and/or soft diisocyanates incorporated into the backbone are used to provide cured polyurethane coatings having a high hard segment content and low haze. The polyurethane prepolymers can also be used to improve the dispersion of filler in cured polyurethane compositions having a high filler loading. Cured coatings prepared from the two-part polyurethane systems meet the requirements for aerospace applications.
