Alkyd Resins for Ambient Temperature Drying Coatings
Alkyd resins are formed by the condensation reaction of oil or fatty acid, acid and polyol. They are used in various applications and materials. In particular, medium and long-oil alkyd resins and modified alkyd resins can form strong films when dried with a dryer.
