摘要：

The water content of 12 paints on steel, exposed to 0. 1M sodium chloride at 25 C for 24 hr, is calculated from impedance measurements and compared with gravimetric determinations. Brasher's empirical expression is compared with five mixture formulas derived from the theory of dielectric properties of heterogeneous substances by Boettcher, Bruggeman, Looyenga, Wagner, and Rayleigh. The 12 paints were based on two grades of red lead and iron oxide in epoxy, chlorinated rubber, alkyd, and linseed oil binders. Results for cyclic wet/dry paint tests according to the difference between the water absorption and desorption rates of a single paint and testing of different types of paints in the same program are discussed.
