Did you know2024
Michelman's Hydrosize aqueous fiber sizing agents are critical to carbon fiber composite manufacturing — the thin polymer coating applied to individual carbon fiber filaments before weaving and resin impregnation. Without the correct sizing chemistry, the interfacial bond between carbon fiber and epoxy matrix is weak, and the composite doesn't achieve design strength. Michelman's Hydrosize products are used in the carbon fiber that goes into Boeing 787 Dreamliner fuselage panels, wind turbine blades, automotive structural components (BMW i3, McLaren supercars), and military aircraft structures. The same Cincinnati, Ohio company that makes the water-based polymer emulsions coating agricultural seeds also makes the invisible molecular adhesion layer that allows carbon fiber composites to carry structural loads in commercial aircraft, fighter jets, and offshore wind turbines. A Michelman production disruption would simultaneously affect agricultural seed treatment supply chains AND advanced composite manufacturing for aerospace and energy.

The carbon fiber sizing market — the polymer coating applied to carbon fiber to enable composite manufacturing — is served by only a handful of specialty chemical companies: Michelman (US), Hexion (US), Evonik (Germany), and a few specialized Japanese producers. Carbon fiber itself is manufactured by Toray, Hexcel, SGL Carbon, and Teijin — but the sizing chemistry that makes the fiber usable in composites is supplied separately. A sizing specification change or supply disruption would require re-qualification of the composite material system — a process that takes 12-24+ months in aerospace applications (FAA/EASA process approval) and 6-12 months in automotive (OEM structural approval). Michelman's position as a qualified sizing supplier to aerospace composite manufacturers creates the same high-switching-cost, small-supplier dynamic seen across other critical industrial chemicals where the material cost is trivial but the qualification cost is prohibitive.
Michelman, Inc. ↗Origin2024
Michelman was founded in 1949 in Cincinnati, Ohio by Richard Michelman, initially producing emulsified wax products for paper and paperboard surface treatment. Cincinnati's chemical industry heritage (Procter & Gamble, Ashland Chemical, Cintas) provided an ecosystem for specialty chemical development. Over 75 years, Michelman expanded from wax emulsions into polymer emulsions, fiber sizings, and digital printing primers through sustained R&D investment rather than acquisition. They remain privately held — an unusual structure for a company with estimated revenues of $200-300M+ operating in capital-intensive specialty chemicals. Private ownership has allowed Michelman to make 10+ year R&D investments in sustainable packaging coatings (replacing non-recyclable PE-laminated paper with compostable aqueous barriers) and carbon fiber sizing without short-term earnings pressure.
