Horgen, Switzerland - A technology called designed diffusion for waterborne coatings improves and accelerates early property development in such latex coatings so that formulators and end users have the option to be able to lower VOCs, according to a paper given by Dow Coating Materials at the European Coatings Conference on 12 Nov in Berlin, Germany.
The DD approach also improves line productivity and reduces energy requirements, said a Dow statement.
The paper, 'Synergistic Waterborne Acrylic Urethane Systems,' shows how coatings formulators can meet the increasing pressure to reduce volatile organic compounds (VOCs). "DD technology is helping to meet environmental regulations without compromising film performance," said author Andrew Swartz of Dow Coating Materials, part of Dow Chemical Co.
To gain the proper hardness and resistance to mar, block, print and dirt pick-up, "latex-based industrial coatings need high glass transition (Tg) polymers," Swartz added.
"More and more, the coatings industry is being asked to comply with a wider range of regulations. We look forward to sharing information that can provide innovative solutions to the industry that assist in the reduction of VOCs without sacrificing product quality," added Dr Andrew Trapani, technical director EMEA, Dow Coating Materials.
