Trial Purpose:
To evaluate reformulated product on six supplied inks.
Date Run:
08/19/2008Experiment Procedure:
Coupons were coated with each of the six supplied inks. These included Dykem Stop Off, Markal Valve Action Paint marker, Nu-Mark marker, Sharpie permanent marker, Sakura Coatings Product Company Solid Marker and the Avery Marks-A-Lot permanent marker (black). Once dry, coupons were cleaned using a handheld swab that was immersed into the cleaning product. Cleaning lasted for up to 2 minutes (if necessary). Following the cleaning, the coupons was wiped once to dry surface. Observations were made and recorded. Product was used at full strength.
Trial Results:
| Vertec Bio Gold 35 | |
| Inks | Results |
| Dykem | Effective in under 30 seconds |
| Markal | Effective in under 30 seconds |
| Nu-Mark | Effective in under 30 seconds |
| Sharpie | Effective in under 30 seconds - little to no blue residue |
| Sakura | Effective in under 30 seconds |
| Avery | Effective in under 30 seconds |
Success Rating:
Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended.Conclusion:
The formulation was found to be effective on all six of the supplied inks. The Sharpie ink removal was better than the previous formulation.
