Surface Preparation
TM
The following surface preparations were used for substrates described in this Technical
Data Sheet.
A. Aluminum Etch
B. Oakite Degrease
C. MEK/Abrade/MEK
D. Isopropyl Alcohol Wipe
E. Isopropyl Alcohol/Abrade/Isopropyl Alcohol
Optimized FPL Etch - 3M (test method C-2803)
1. Alkaline degrease – Oakite 164 solution (9-11 oz./gallon water) at 190°F ±
2. Optimized FPL Etch Solution (1 liter):
3. Rinse immediately in large quantities of clear running tap water.
4. Dry – air dry approximately 15 minutes followed by force dry at 140°F
5. Both surface structure and chemistry play a significant role in determining
Oakite 164 solutions (9-11 oz./gallon of water) at 190°F ± 10°F (88°C ± 5°C) for
2 minutes. Rinse immediately in large quantities of cold running water.
Wipe surface with a methyl ethyl ketone (MEK) soaked swab, abrade and wipe
with a MEK soaked swab.* Allow solvent to evaporate before applying adhesive.
Wipe surface with an isopropyl alcohol soaked swab.* Allow solvent to evaporate
before applying adhesive.
Wipe surface with an isopropyl alcohol soaked swab, abrade using clean fine grit
abrasives, and wipe with an isopropyl alcohol soaked swab.* Then allow solvent
to evaporate before applying adhesive.
*Note: When using solvents, extinguish all ignition sources, including pilot lights,
10°F (88°C ± 5°C) for 10-20 minutes. Rinse immediately in large quantities
of cold running water (3M test method C-2802).
Material
Distilled Water
Sodium Dichromate
Sulfuric Acid
Aluminum Chips
To prepare 1 liter of this solution, dissolve sodium dichromate in 700 ml of
distilled water. Add sulfuric acid and mix well. Add additional distilled water
to fill to 1 liter. Heat mixed solution to 66 to 71°C (150 to 160°F). Dissolve
1.5 grams of 2024 bare aluminum chips per liter of mixed solution. Gentle
agitation will help aluminum dissolve in about 24 hours.
To FPL etch panels, place them in the above solution at 150 to 160°F (66 to
71°C) for 12 to 15 minutes.
Note: Review and follow precautionary information provided by chemical

bond or prime freshly primed clean surfaces as soon as possible after surface
preparation in order to avoid contamination and/or mechanical damage.
