The Chemline Story


Chemline was founded in 1997 in John Pantanella’s garage. Three years before founding the company, he was working nights and weekends to develop a handful of products that would launch Chemline. In the early days, Chemline rented lab space and had access to fractional office and warehouse staff from another coatings manufacturer. They answered phones and shipped product while John traveled the eastern United States selling Chemline products.

After eight months, a steel tank manufacturer located in North Carolina gave Chemline its first order. Word spread quickly about the performance of Chemline products and exceptional service. Sales to other steel fabricators of tanks, pipes and poles followed. With steady sales from several loyal customers, Chemline was able to hire a few industry all-stars and build on the early success of the company.

In 2005, Chemline purchased a 100,000 sq. ft. facility in St. Louis, Missouri, which became company headquarters. After multiple acquisitions and rapid growth, Chemline added several full-time industry professionals to manage operations, sales and research functions.


Chemline continues to grow rapidly as we strive to be the best in class. Chemline now has approximately 100 employees between two facilities in St. Louis, Missouri and Los Angeles, California. The head office is located in St. Louis and, after an extensive plant expansion, now occupies a 250,000 sq. ft. facility where the most up-to-date chemical processing technology enables Chemline to quickly produce a wide range of polyurethane resins. Chemline also has multiple state-of-the-art laboratories where chemists work to create the next generation of polyurethane formulations. With an ever-expanding facility and competent management team in place, Chemline has scaled to become the largest privately held polyurethane system’s business of specialty elastomers and coatings.

“Thank you to our loyal customers for making this such a great story – we remain forever grateful.”
