Acryloid B-67 is made by Rohm and Haas and is a resin based on a isobutyl methacrylate polymer. It is an alkyd-compatible acrylic ester resin particularly designed to have good compatibility with medium and long oil alkyds. The addition of Acryloid B-67 to alkyds, oils or varnishes produces coatings of improved hardness, faster drying speed, better color and gloss retention and improved hold out and brushing characteristics. Acryloid B-67 is available as a 100% resin in the form of beads, or in solution, supplied as 45% solids in mineral spirits. Acryloid B-67 produces a clear film with an ultimate hardness of 11-12 KHN and a glass transition temperature of 50 (Tg°C).
