Need PPG/Omni tech sheets

I need to find tech sheets for PPG deltron DBC500 , Omni MP180, and MBC9300. I went to the PPG website and found each of the products, but when I click on the PDF file for the tech sheet, all I get is pages of random letters and numbers. Where else can I find these tech sheets or what am I doing wrong on the PPG site? Thanks in advance!
