PPG makes paints, coatings, and specialty materials for surfaces across a broad range of end markets, including buildings, cars, aircraft, ships, bridges, packaging, and industrial equipment. PPG operates through three segments: Industrial Coatings (~43% of sales), Performance Coatings (~33%), and Global Architectural Coatings (~24%). Industrial Coatings covers factory-applied coatings for automotive OEMs, packaging, appliances, and industrial equipment — often with PPG teams embedded directly inside customer plants. Performance Coatings is the highest-margin segment and focuses on aftermarket customers in aerospace, automotive refinish, protective and marine, and traffic solutions. The aerospace business is growing fastest, covering coatings, sealants, and transparencies for commercial and military aircraft. In automotive refinish, PPG has built a digital ecosystem of mixing equipment and software subscriptions that adds recurring revenue on top of paint sales. Global Architectural Coatings covers decorative paints for residential and commercial construction, with PPG's strongest positions in Mexico (via the Comex brand and ~5,200 concessionaire stores) and across EMEA. PPG manufactures primarily local-for-local, limiting tariff exposure. Profitability is driven by volume, pricing, and raw material costs — resins, solvents, TiO2, and pigments are the largest cost input. PPG's strategy focuses on organic growth, portfolio sharpening through recent divestitures of lower-margin businesses, share gains in automotive OEM and packaging coatings, and over $500M in aerospace capacity expansion.
