Charlotte, North Carolina -- Visitors to the recent American Coatings Show (ACS) in Charlotte, North Carolina, had the opportunity to attend a tutorial on the evolution of polyurethane chemistry from Bayer MaterialScience.
"Tutorial 4 -- Polyurethanes," led by Myron Shaffer, product performance manager at BMS, looked at how PU chemistry has evolved to include diverse formulations such as an additive to curing agents in coatings, aqueous PU dispersions and two-component urethane coatings, as well as the role of isocyantes, UV curable urethane acrylates and other PU technologies in coatings, a 14 April BMS statement said.
"Understanding how a polyurethane system's chemical make-up affects its properties allows formulators to customise the resin system to meet a variety of application needs across many different markets," Shaffer said to attendees of the tutorial, giving an insight into how the structures of PU systems relate to end-use applications and properties.
Other topics included the use of PU coatings in personal-care products and medical products, benefiting from polyurethanes non-wear properties and its strength and elasticity, respectively, the statement said. (RD)
