UV Coating Cure Verification Log - MEK Double Rub

Inspection log for recording MEK double-rub counts, tack checks, and adhesion observations to verify UV or electron-beam coating cure and establish a job-specific baseline pass/fail result.

Inspection Details

• Job / work order identifier recorded
• Inspection date and time recorded
• Inspector name and department recorded
• Coating process identified as UV or EB
• Reference SOP or test procedure available
• Product, substrate, and coating lot numbers recorded

Test Setup and Sample Identification

• Test panel or production sample identified
• Test area cleaned and free of visible contamination
• MEK solvent and applicator prepared for test
• Rub direction and test area defined before starting
• Ambient conditions recorded if required by procedure

MEK Double-Rub Results

• Baseline double-rub count achieved before coating softening or transfer
• Coating surface remained intact during test
• No tackiness observed after solvent rubs
• No visible color transfer, smear, or coating lift observed

Adhesion and Cure Assessment

• Adhesion remained acceptable after MEK rub test
• Cure result meets job specification or baseline requirement
• Any evidence of incomplete cure, softening, or solvent attack

Disposition and Corrective Action

• Product released for next process step
• Non-conformance or corrective action documented when required
• Disposition selected
