Rinse immediately in large quantities of cold running water. 3. Acid etch – Place pannels in the following solution for 10 minutes at 150F+/- 5F (66C +/- 2C).* 1. Sodium Dichromate oz./gallon 2. Sulfuric Acid, oz./gallon T3 aluminum (dissolved)0.2 oz./gallon minimum 4. Tap waterBalance of volume 4. Rinse – Rinse panels in clear running tap water. 5. Dry – Air dry 15 minutes; force dry 10 minutes at 150F +/- 10F (66C +/- 5C) 6. If primer is to be used, it should be applied within 4 hours after surface preparation

31 3 Aerospace Cleaning methods  Plastics 1. Solvent wipe with Isopropyl Alcohol * 2. Abrade using clean fine grit abrasives 3. Solvent wipe again with Isopropyl Alcohol *  Rubbers 1. Solvent wipe with Methyl Ethyl Ketone (MEK)* 2. Abrade using clean fine grit abrasives 3. Wipe again with MEK *  Steel 1. Wipe free of dust with oil-free solvent such as Methyl Ethyl Ketone (MEK)* 2. Sandblast or abrade using clean fine grit abrasives 3. Wipe again with solvents to remove loose particles

32 3 Aerospace Cleaning methods  Glass 1. Solvent wipe with Acetone or Methyl Ethyl Ketone (MEK)* For glass applications which will be subjected to high moisture/humidity conditions, a primer should be used to prime the glass * Note: When using solvents or chemicals, be shure to extinguish all ignition sources and follow the manufacturer’s precautions and directions for use when handling such materials * Note: When using solvents or chemicals, be shure to extinguish all ignition sources and follow the manufacturer’s precautions and directions for use when handling such materials
