Question

Which base coat is preferred for a low absorbency crust leather?

• A. Sealing Coat
• B. Clearing Coat
• C. Impregnation Coat
• D. Both (a) and (c)

Hint:

For low absorbency leather, Sealing Coat and Impregnation Coat are preferred to ensure even finishing and prevent excess absorption.

Answer 1

The Correct Option is D

Step 1: Understanding the Base Coats
- Sealing Coat: This is typically applied to prevent excessive absorption of finishing materials, especially in leathers with low absorbency.
- Clearing Coat: Generally used to remove any impurities and improve the overall finishing process but is not specifically aimed at low absorbency.
- Impregnation Coat: This is used to seal the surface and help with the uniform distribution of the final finish, especially for low absorbency leathers.

Step 2: Conclusion
For low absorbency crust leather, both Sealing Coat and Impregnation Coat are commonly used to improve absorption properties and ensure uniform finishing.
