Pursell Agri-Tech and Huntsman expand portfolio with coating related patent

Pursell Agri-Tech and Huntsman International recently announced the issuance of a U.S. Patent relating to the PurActive polyurethane-based coating technology used in the production of controlled-release fertilizer (CRF). The technology is set to serve a broad range of markets including turf and ornamental and consumer home and garden.

“The PurActive coating technology leverages Huntsman’s advanced Rimline polyurethane system and optimized processes to produce controlled-release fertilizer at faster batch times, lower processing temperatures and with a much thinner coating weight,” said Jan Buberl, vice president, Huntsman Polyurethanes Americas. “These unique advantages translate into lower energy usage and a reduced carbon footprint.”

University trials conducted on behalf of Pursell Agri-Tech demonstrated that the PurActive technology also protected the core fertilizer substrate and minimized nutrient loss, greatly reducing volatilization and leaching.

According to the company, the PurActive coating technology is thinner and allows for higher nutrient content per ton. The lower processing temperature promotes the survivability of such health-boosting additives as micronutrients, microbials and biostimulants.

“We are committed to introducing CRF technology that helps reduce greenhouse gas emissions and improve water quality,” said Taylor Pursell, chairman, Pursell Agri-Tech. “This patented coating technology has proven its ability to do this while allowing us to offer customers a broader portfolio of coated substrates and numerous product features previously unavailable.”
