Sells proprietary ZERUST corrosion-prevention products and Natur-Tec bio-based, compostable resins and finished products. Revenue comes from direct sales, subsidiaries, and a network of manufacturing-and-marketing joint ventures.
ZERUST supplies rust- and corrosion-inhibiting products and services to automotive, industrial, mechanical, mining, agricultural, retail-consumer, and oil-and-gas markets. Natur-Tec supplies bio-based and compostable polymer resins and finished products.
ZERUST and Natur-Tec are the reportable segments. Operations combine direct sales with subsidiaries and joint ventures, including a worldwide ZERUST distribution network whose local partners manufacture and market products in assigned territories.
The company participated in 15 active joint ventures across North America, Europe, and Asia. This model relies on local partners’ regulatory and market knowledge, while raw-material costs and competitive Natur-Tec pricing can affect margins.
