In the previous paper, the present author gave a description of a fundamental investigation about the molecular structure and the mechanism of “Solvent-Cracking” on brittle lacquer coating prepared from calcium rosin as a basic ingredient, in order to find out the effectiveness improving strain sensitivity of coating contacted with various media.
In this report, the interaction between the coating and various media is analyzed by considering the factors as follows:
The analysis of interaction will be comparatively easy, if the media are non-polar, but these media used for improvement of strain sensitivity are generally polar such as polyfunctional alcohols having a complicated molecular shape and strong association tendency.
As the result, it was been concluded that the interaction between coating and media, namely, the effectiveness improving the strain sensitivity of coating is proportional logarithmically to the initial dissolving rate of various media.
