Abstract: The high-pressure phase behavior of coating-solvent-supercritical or sub-critical carbon
dioxide system was investigated experimentally. The coating matrix used was 108-acrylic
resin at concentration ranging from 10% to 50% (by mass) in mixtures with n-butyl acetate.
The experiments were conducted in a high-pressure view cell for temperatures from 35℃ to
65℃ and for pressures from 3.0 MPa to 8.0 MPa. The effect of temperature, pressure and
content of every component on the phase behavior of the systems was observed. Finally, the
ternary phase diagram for resin-solvent-CO2 was plotted.

Key words: phase behavior, supercritical CO2, coating matrix
