Acrylic oligomer for high solid automotive top coating system having excellent acid resistance

Ichiro Azuma; Norio Kosaka; Goro Iwamura; Yoshiaki Marutani; Hiroyuki Uemura

Acrylic oligomers containing siloxy groups were synthesized using trimethylsiloxyethyl methacrylate (TMSEMA) which have lower polarity and lower viscosity than those containing naked hydroxyl groups, and developed as high solid automotive top coatings by application of the crosslinking reaction between the siloxy groups and isocyanate groups or by the hybrid crosslinking reaction using the siloxy groups, epoxy groups, acid anhydride groups and hydrolyzable silyl groups. The hybrid crosslinked films show excellent acid resistance and scratch resistance.
