Project Number 1
Summary:
Steam was determined to be effective at removing the wax when used as either the first or last stage. With rinse bath temperatures near 212 deg F, trace wax removal was almost complete.Test Objective:
Alternative to TCE vapor degreasing and dewaxingProduct Use:
customer's parts| Trial Number | Date Run | Purpose | Success Rating |
|---|---|---|---|
| 0 | 06/04/1997 | Determine the effectiveness of six test solutions | A cleanliness study, addressing only various analytical techniques. |
| 1 | 06/05/1997 | Is electrostatic charge causing high contact angle | A cleanliness study, addressing only various analytical techniques. |
| 2 | 06/11/1997 | Determine effectiveness of selected cleaners | Test showed little or no promise. |

Project Number 2
Summary:
Two products were found to work well on the Red Stop off lacquer using ultrasonic cleaning. Both had success at manual removal of excess lacquer as well. Products were evalauted on-site to determine actual effectiveness in the field.Test Objective:
Replace MEK with greener solvent| Trial Number | Date Run | Purpose | Success Rating |
|---|---|---|---|
| 0 | 03/03/2008 | To identify possible aqueous products for removal of lacquer from aluminum parts | Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. |
| 1 | 03/03/2008 | To evaluate non-aqueous alternatives for removing the supplied lacquer | Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined. |
| 2 | 03/04/2008 | To evaluate promising alternatives using increased operating conditions, time, temp and agitation | Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. |
| 3 | 03/04/2008 | To evaluate top two performing products using extended immersion cleaning | Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. |
| 4 | 03/05/2008 | To evaluate two products on supplied parts using ultrasonic cleaning | Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. |
| 5 | 03/05/2008 | To evaluate two products on supplied parts using extended immersion cleaning | Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. |
| 6 | 03/18/2008 | To evaluate top two products for spot cleaning on supplied parts using swabs | Results suggest a scale-up feasible match for cleaning chemistry and equipment. Pilot plant study with actual parts recommended. |
| 7 | 04/01/2008 | To replace methyl ethyl ketone in the removal of lacquer from aluminum parts. | Technology Transfer. |
| 8 | 05/02/2008 | To conduct on site testing to replace methyl ethyl ketone in the removal of lacquer from aluminum parts. | Technology Transfer. |
