Abstract

The Radiometric Emanation Method (REM) was used for the characterization of barrier properties of protective coatings. Radon diffusion parameters of the hardened protective layers prepared from ORMOCER lacquers of varying compositions were examined. The differences in the barrier properties of non weathered and weathered ORMOCER coatings, as well as of INCRALAC coatings, were compared.

REM is recommended for the characterization of barrier properties of protective coatings submitted to weathering at varying conditions and time.
