Function of wetting agents used in casting procedure is_________________?
Correct answer: C. To reduce contact angle of liquid with max surface
- A. To felicitate wetting of ring liner
- B. To felicitate mixing investment
- C. To reduce contact angle of liquid with max surface
- D. For better wax elimination
Explanation
A wetting agent lowers the contact angle between the liquid and the wax pattern or investment surface, allowing the liquid to spread more completely and reducing surface defects. It is not primarily used to improve investment mixing or wax elimination.
