Perstorp, Sweden - The performance of UV/EB cured coatings can be radically improved by using Oxymer polycarbonate diols from speciality chemicals company, Perstorp, an 18 March press statement claims.
The R&D team at Swedish group Perstorp has developed a new use for Oxymer diols which is a significant breakthrough for formulators, the company says.
Coatings developers can produce coatings cured via UV/EB (ultraviolet/electron beam) routes with "excellent UV and chemical resistance, hydrolytic stability and outdoor weatherability," by using the Oxymer diols to make urethane-acrylate oligomers, according to Perstorp.
The Oxymer products will allow users to meet growing demands for tougher, longer-lasting end products, the company added.
"Our Oxymer range is already helping formulators achieve outstanding outdoor durability and chemical resistance in polyurethane dispersions and we expect to see similar interest from producers of urethane acrylate oligomers for UV/EB curing," explained Perstorp market development manager David James, in a company statement.
"Polycarbonate diols represent a winning technology that is growing very quickly and taking market shares from other macrodiols," added business development director Hakan Bj??rnberg.
