Services
Steel Pickling Additives
Crown Technology develops specialized inhibitors and accelerators for steel pickling processes. These chemical solutions protect base metals during acid treatment while improving line speeds and reducing acid consumption. Our products cater to both hydrochloric and sulfuric acid applications, offering formulations for standard and high-reactivity steel grades.
Ferrous Sulfate Products
As North America's leading supplier, we produce high-purity ferrous sulfate in multiple forms. Our products serve agricultural, pharmaceutical, and water treatment industries, meeting strict quality standards. Applications include fertilizer micronutrients, soil remediation, and analytical chemistry reagents with 14% iron content.
Acid Recovery Systems
Our patented acid recovery technology enables steel mills to reclaim and reuse sulfuric acid from pickling processes. This system reduces waste, lowers operational costs, and produces marketable ferrous sulfate by-products. Available in 2-25 GPM capacities with corrosion-proof construction.
Industrial Cleaners
We manufacture heavy-duty cleaning solutions for industrial facilities, including galvanize precleaners and concrete removal agents. Our formulations effectively remove oil, grease, and mill dirt from equipment and floors while maintaining environmental compliance and worker safety.
Toll-Blending Services
Crown offers ISO-certified aqueous blending capabilities with annual capacity exceeding 10 million gallons. Our technical team develops proprietary formulations under strict confidentiality agreements, supporting private label production with bulk packaging options from 55-gallon drums to 330-gallon totes.
