In one of our Industrial processes we utilize a product called PR-420 Part B - I have made numerous inquiries with the manufacturer PPG Aerospace PRC-Desota, to no avail. I am seeking information regarding 'Silicic acid, chromium lead salt' (CAS # 11113-70-5) and whether this chromium based chemical constituent is in fact Hexavalent. My research has led to it being only trivalent however i was hoping that of the pool of industrious engineers out there, one may be able to provide objective quality evidence to confirm or deny my claim. So the question is - is the chromium Hexavalent or not? Thanks in advance for any research or information anyone can provide. I apologize if this is the incorrect forum.
