Abstract : New environmental regulations have prompted the need for organic coatings with low volatile organic compound (VOC) levels that maintain the properties of their high VOC counterparts. Loss of solvents creates such problems as poor film formation and high application viscosity. The effects of low molecular weight polymers and reactive diluents in coating formulations were studied with respect to properties deemed essential for overall operational readiness of naval aircraft. Such materials were incorporated into a compliant, high-gloss epoxy topcoat. While attempts to improve the properties of the topcoat under extreme conditions were unsuccessful, the new system met all the requirements of MIL-C-22750, the Military Specification for an epoxy topcoat. The coating also exceeded the performance of the control formulation in many categories, including a reduction of VOC's by 40%.
