Abstract:

This Toxicology Assessment was conducted in accordance with ASTM Guideline E-2552. Compounds evaluated are part of an effort to develop non-isocyanate-based polyurethane coatings for protection of erosion-prone components of military equipment and aircraft, such as helicopter rotor blades. Eight perfluorinated compounds were evaluated. In most cases, experimental data were not available, so predictions were made using Quantitative Structure-Activity QSAR models. In common with other perfluorinated compounds, many of these compounds are predicted to be developmental or reproductive toxicants, and to be recalcitrant in the environment. Compounds structurally similar to bisphenol A are at least potential endocrine disruptors. The two most favorable compounds are 2-difluoroiodomethyl-2,3,3-trifluorooxirane and 2,2,3,3,4,4,5,5-octafluorohexane-1,6-diamine. In vitro experimental testing is recommended.
