Did you know2023
Sherwin-Williams is publicly known for house paint, but through the 2017 Valspar acquisition they became the dominant North American supplier of food can interior coatings — the thin polymer film lining the inside of every tin can of soup, vegetables, and pet food that prevents metallic taste and corrosion. The valPure product line (formerly Valspar) became a strategic asset as consumer and regulatory pressure drove the phase-out of BPA (bisphenol A) from food can linings. Sherwin-Williams and PPG together form an effective North American duopoly in food can coatings. Every Campbell's soup can, Del Monte vegetable can, and Purina wet pet food can uses a Sherwin-Williams or PPG interior coating. A paint company typically associated with houses and bridges controls whether canned food is safe to eat and whether canned food tastes like metal or tomatoes. The BPA alternative chemistry developed by Sherwin-Williams for food cans is one of the most consequential food packaging material decisions in recent decades, with no competitive alternative at scale.

Henry Sherwin and Edward Williams founded Sherwin-Williams in 1866 in Cleveland, Ohio with a revolutionary business model: selling ready-made paint in sealed tin cans. Before Sherwin-Williams, painters mixed their own pigments and linseed oil on the job site — a skilled trade requiring knowledge of pigment ratios, drying times, and oil quality. Sherwin's innovation was industrial consistency: factory-mixed paint with known performance. The company later invented the resealable paint can (1877) and developed the first truly washable house paint. This consistency-at-scale concept made Sherwin-Williams dominant as building construction industrialized in the 20th century. The company also developed lead-based paints that were standard for over a century — the same Sherwin-Williams that makes FDA-compliant food can linings today paid a $409 million settlement in 2019 for childhood lead paint poisoning claims stemming from its pre-1978 lead paint products. A company that pioneered industrial paint manufacturing also created one of the largest US toxic legacy liabilities.
