Mold release agents can cause which issue?

• A. Corrosion
• B. Poor paint adhesion
• C. Cracking
• D. Warping

Answer: (B)

Mold release agents leave a residue on the surface that prevents paint from bonding properly. This film blocks proper wetting and adhesion of primer and topcoat, so the paint doesn’t stick well and finish quality suffers. The other issues—corrosion, cracking, and warping—come from moisture, stress, or substrate deformation, not from surface contamination by release agents when the surface is correctly cleaned. To prevent this, thoroughly remove any release residue with a wax-and-grease remover or appropriate solvent and ensure the surface is clean and prepared before painting.
