Another reader pointed out that the QQ-P-416, Type II, Class 2 specification clearly states that the conversion coating is not intended for long-term exposure to temperatures over 150F or to intermittent exposure over 300F.

A "strict" interpretation of the specification would not allow you to bake the parts at the temperatures specified in the question. However, you might be able to produce useable parts if the final use of the parts is not too demanding.
