MSDS's are very useful and have good information for using what ever it is describing. But, unless it is for a material specifically designed for potable water systems I think you're giving too much credence to the info contained in them.
You will not get the applicable information you need to make that decision.
From GAF's website:
"TOPCOAT® Membrane WOB White is included on the list of approved potable water catchment coatings by the Bermuda Department of Health. TOPCOAT®Membrane WOB White has been tested and certified by the NSF International as an approved potable water catchment coating that complies with requirements of “NSF Protocol for Health Effects of Rainwater Catchment System Components dates August 1, 1995.” The ingredients of TOPCOAT® Membrane WOB White are listed by the U.S. Food and Drug Administration."
Before actually committing I would verify these claims.
For now, I accept them in deciding which ones to consider.
Plus, I had forgotten to mention that the white non pigmented coating is rated at 85% reflective for cutting heat transference through the roof.

Was a Democrat until gun control became a knee jerk, then a Republican until the crazies took over, back to being a nonpartisan again.
This time, I can no longer participate in the primary.
