Assessment of water uptake in coil coatings by capacitance measurements (vol 46, pg 55, 2003)

摘要

A model for the estimation of water uptake in polymeric coatings is presented, based upon a linear combination of the individual capacitances of the polymeric phase, the water and the air contained in the coating. Experimental comparison of the model with the Brasher-Kingsbury (BK) equation has revealed an improvement in the agreement with respect to the gravimetry. [References: 1]
