Technical Information paint

Use in coating applications Use of DURANOL™ allows you to obtain a polyurethane paint with excellent scratch resistance, chemical resistance, Abrasion resistance, and weather resistance. Above all, liquid type DURANOL™ is amorphous and its stress at a low strain is smaller than that of solid type PCD, thus it can offer softer feeling as a binder of a soft feel paint. Additionally, its solubility to solvents is high and thus, for solvent paints, allows reduction of the amount of solvent used and higher solid content. Furthermore, for water-based paint, it disperses into water with a small amount of solvent (or without solvent) and thus allows environmentally friendly paint design. DURANOL™ is used in a wide range of fields such as automobile, home appliances, mobile devices, and general industries

Chemical resistance of DURANOL™

It can be seen that PCD polyurethanes have a smaller swelling rate due to organic solvent when compared to polyether urethanes and polyester urethanes and copolymerized type DURANOL™ has an excellent swelling rate in particular.
