Which statement about temperature and finishing is true?

Temperature controls how fast solvents leave the coating and how the film flows and cures. In finishing, you want a balance: enough solvent to let the film level out and form a smooth layer, then it should evaporate at a rate that lets the film harden without defects. If the temperature is too high, solvents flash off too quickly, which can cause issues like wrinkling, solvent popping, or micro-cracks and reduced gloss because the film doesn’t have time to flow and level properly. If the temperature is too low, evaporation slows, the film may stay tacky longer, flow poorly, and you can end up with orange peel or sagging and a dull finish. So, temperature truly affects both solvent evaporation and film formation, and extreme temperatures lead to defects.
