As discussed before, low viscosity of the film is an important factor for better flow and leveling. With progressive evaporation of the sol­vents, the viscosity of the coating film increases rapidly. Therefore, slowly evaporating, active solvents are good leveling agents that allow sufficient time for the liquid film to level out any unevenness. Among the slow evaporating solvents, the choice is largely depen­dent on the binder system. Typical solvents are hydrocarbons such as alkylbenzenes, high boiling paraffinics, terpene solvents, esters such as lactates and esters of glycol ethers, ketones such as methyl amyl ketone, and glycol ethers such as 2-butoxyethanol.
