- A.
To prevent mottling
- B.
To prevent bridging
- C.
To quicken spreading of the coat before complete evaporation occurs
- D.
To make the solvent evaporation slow
Correct Answer
C. To quicken spreading of the coat before complete evaporation occursExplanation
Surfactants are used in the non-aqueous film coat to quicken the spreading of the coat before complete evaporation occurs. Surfactants are compounds that lower the surface tension of a liquid, allowing it to spread more easily. In the case of a non-aqueous film coat, the surfactant helps to evenly distribute the coat over the surface before it evaporates. This prevents mottling, which is the uneven distribution of the film coat, and also prevents bridging, which is the formation of gaps or unevenness in the coat. By quickening the spreading process, the surfactant ensures a smooth and uniform film coat.Rate this question:
