I have learned that when searching for paint product MSDS's and Product Data Sheets for jobs we are doing at work, I don't get trapped in a revolving door by going to the MFG website. Instead, I Google a string something like this:
SEARCH BOX ENTRY PPG delstar MSDS PDF or PPG Deltar flatener PDF
In my experience, this will get right whereyou need to be. These documents are usually in PDF format and by putting that in the search string, it filters out all the riff-raff.
