ICE-PHOBIC CHARACTERISTICS OF THE DEICING SYSTEM COMPRISING THE Navy gray deck paint system, an A4014 primer with the Compound 23 was investigated. For a material to be considered icephobic, the values for ice adhesion should remain below 15 psi for 10 repeated ice releases with water immersion between successive releases. Results of ice adhesion tests on samples of 24 different pro uction lots of Compound 23 yielded ice-adhesion values in the ice-phobic range on the first test none of the lots maintained its ice-phobicity upon repeated test cycling. Determination of the ice adhesion of this compound appears to give an extremely sensitive indication of minute differences which may be inherent in the preparation of polysiloxanes.
