New polyaspartic coatings improve throughput speed by reducing handling times

Mike Jeffries, Strategic Technology Manager, aliphatic isocyanates and polyaspartics, Bayer MaterialScience LLC, discussed the benefits of polyaspartic coatings for steel construction during a presentation entitled "Polyaspartic Coatings: Next-Generation of Durable Shop and Field Applied Finishes," as part of the Advances in Polyurethane Technology conference. This event, sponsored by the American Coatings Association, was held 14 - 15 September 2011 in Charlotte, NC, USA. During his presentation, Jeffries detailed polyaspartic coating chemistry and its features, including improved shop and field throughput by reducing handling time, fast cure at ambient and low temperatures, high film build and proven durability. He also highlighted the results of independent ambient and cold temperature tests comparing handling times of current coating technologies with next-generation polyaspartic coatings. More specifically, he described initial ambient test results indicating that polyaspartic coatings offer better resistance to abrasive/dust pick up and compression damage. Furthermore, according to Jeffries, cold temperature testing showed polyaspartic coatings outperformed current coating technologies in resistance to abrasive/dust pick up, compression damage, and contact point damage.
