Abstract:

Elimination of isocyanates alleviates a major occupational health and safety concern in the manufacture and use of solid rocket motor propellants. Replacement of isocyanates with chemical groups that are ubiquitous in the biosphere will greatly reduce the risk associated with future regulation obsolescence throughout the manufacturing, use, and de-militarization life cycle. Alternative cure chemistries that are successful for solid rocket motors may be transitioned to other applications, such as paints, foams, sealants, and adhesives that also represent a significant source of occupational health risk for DoD and DOE.
