MIL-PRF-32348 Class Distinction

Q. In MIL-PRF-32348 [link is to free spec at Defense Logistics Agency, dla.mil] (Powder Coating, Camouflage Chemical Agent Resistant Systems), 2 different classes are mentioned. Are there any advantages to either of these classes? Besides the different maximum temperatures reached, what are the differences of these two classes?

"Class I - No limitation on maximum temperature reached by substrate during coating cure.
Class II - Maximum temperature of 350F (177C) reached by substrate during coating cure."
