文摘

Cosolvent retention is related to its evaporation and solvent-polymer interaction;. Surface mechanics increases over time as residual cosolvent evaporates;. Butyl glycol evaporates too fast to ensure full coalescence yet results in stiffest coating;. Texanol stays in the coating for better film formation but deteriorate the surface stiffness.
