AP400 approval

[Mahnaz Mansourpour]

Hello

The chemical has been approved previously. Please use it at headway and 
take all the precaution  that applies to HMDS. Please see me if you have 
any other question or process question , I have used it myself.
Please come by my office and do the proper paper work and get the label 
and the barcode before the chemical finds its way to the lab.
