Eleven Military paint formulations on metal panels were evaluated for fungal susceptibity before and after weathering and leaching. TT-E-527 and TT-E- 529 olive drab and MIL-E-52798A forest green camouflage formulations supported moderate fungal growth after six weeks in plate tests or 13 weeks in tropical chamber tests. MIL-C-46168A chemical agent resistant formulation supported slight growth during this period. Overgrinding or the inclusion of fine beads to improve paint smoothness did not improve fungal resistance of either the MIL-E-52798A or MIL-C-46168A formulations. The addition of 1 or 2 Vancide significantly improved the fungal resistance of MIL-E--52798A but provided only minimal improvement for MIL-C-46168A. Scanning electron micrographs and evaluations of camouflage and chemical agent resistance changes due to fungal growth will be continued during FY83.
