Understanding PPG Aerospace Coating Terminology

PPG has a long history in the Aerospace coating business and this history comprises the integration of different companies and brands. All these companies had their own brands and part numbering systems that were retained for customer continuity. It is why today, PPG’s coatings portfolio is a heritage of these brands and part numbering systems. 

This guide will help you understand the main difference between the part numbering systems, making your product choice easier for DeSoto, Spraylat, Deft and Courtaulds CA. Scroll down to view the full guide.
