FORD LABORATORY TEST METHOD BI 106-03
HYDROLYSIS RESISTANCE OF PAINTED PLASTIC PANELS
Application
This procedure simulates adhesion loss of certain paint formulations over plastic substrates due to heat and
humidity aging.
Apparatus Required
Oven
Forced air circulation, capable of maintaining a temperature of 55 +/- 2 °C.
Glass Jars
250 ml, fitted with aluminum foil-lined lids
Syringe
Calibrated to 0.1 milliliters
Distilled or deionized water
Absorbent tissue or towel
Conditioning and Test Conditions
All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 °C
and 50 +/- 5 % relative humidity for not less than 24 h prior to testing and tested under the same conditions
unless otherwise specified.
Procedure
1. Cut a sample of coated substrate to be tested into a size that will fit in to a glass jar
2. Place sample in to jar. Add 2.0 mL of distilled or deionized water. Secure lid on jar as tightly as

4. Remove the jars from the oven after the specified period time and cool to 23 +/- 2 °C.
5. Note the presence of water condensate in the neck of the jar, and record the date when the jar was
removes from the oven.
6. Open the jar, remove the sample and immediately reseal the jar if there is a possibility of continuing
the test.
7. Blot away condensation on sample being tested with clean absorbent lab tissue or towel. Test
according to FLTM BI 106-01 within 30 minutes.
8. Return unfailed samples back into their respective jars as soon as possible. Replace lost water via
syringe. Hand seal as tightly as possible.
9. Return jars being tested to the oven set for 55 +/- 2 °C.
