High Solids Coating System

Abstract

This contract research effort, a continuation of a previous Air Force supported contract (F33615-77-C-5101), was directed toward the development of a 65% volume solids, sprayable (airless electrostatic method), polyurethane exterior aircraft coasting meeting MIL-C-83286B performance specifications. A high solids coating can significantly reduce solvent emissions and help the Air Force meet EPA/OSHA requirements for reduced environmental pollution and increased worker safety. One formulation, consisting of a combination of Acryloid AU-568 (oxazolidine), NIAX PCP-0300 (polyol), and Desmodur N-100 (polyisocyanate) was developed under the initial contract and found to exhibit performance properties closely approximating the program goals. During the present contract, this formulation was further evaluated. Attempts to upgrade the properties not meeting the performance specifications were made. Also, new commercially available resins were evaluated for incorporation into the high solids systems.
