The DoD has specifically set forth the precise attributes that happen to be present in HCTI chemistry for the components of the industrial coating they require: Google SERDP.
Excerpted from SERDP: 'Currently, the military (Department of Defense) uses polyurethane coatings for many of its applications because they’re durable and perform well. However, the polymers use a group of chemical compounds called isocyanates, which are toxic and very hazardous for human health and safety. This is why there is a lot of interest across the globe, to limit or eliminate the use of isocyanates.'
