Consider the following statements : I. Pine oil is used as antifoaming agent in the emulsion paints. II. Protective colloids are used in the emulsion paints to decrease their stability. III. Driers having oxidizable oils are added to the emulsion paints to accelerate drying process. Which of the statements given above is/are correct?

  1. A. I and II
  2. B. I only
  3. C. II and III
  4. D. I and III

Correct Answer: B. I only

Explanation

Pine oil is frequently used as an antifoaming agent in emulsion paints. Statement II is incorrect as protective colloids are used to increase (not decrease) stability. Statement III is incorrect because emulsion paints dry primarily by the evaporation of water, whereas oxidizable oil driers are used for oil-based paints.
