Permeability of shellac coatings to gases and water vapor

Journal of Agricultural and Food Chemistry, 1991
Shellac was coated onto highly permeable polymer films and its permeability calculated from measured values of permeance for coated and uncoated films. At 75per thousand relative humidity and 30°C, the O*l2*s and CO*l2*s permeability was 230 and 803 cc mil/(m*h2*s day atm), respectively, for Shellac coatings cast from ethanol.

Water Vapor Permeability of Edible Bilayer Films

Journal of Food Science, 1984
ABSTRACT Edible films composed of a water soluble, carbohydrate layer (hydroxypropyl methylcellulose) and various kinds of lipid layers were tested for resistance to water vapor permeability. Films were tested at 25°C and a relative humidity differential of 85%.

Quick determination of water vapor permeability and water vapor resistance of plasters and putties

Construction Materials
The existing methods for determining the coefficient of vapor permeability and vapor permeability resistance of plaster and putty materials are characterized by a long time of the experiment.This underlines the need to create a method for accelerated determination of these indicators, taking into account the simplicity of its practical implementation ...

THE PERMEABILITY OF THE EPIPHRAGM OF TERRESTRIAL SNAILS TO WATER VAPOR

The Biological Bulletin, 1968
1. A method for the measurement of epiphragma permeability is described.2. Permeability coefficients varied greatly, depending on the water content of the epiphragm.3. Permeability coefficients of epiphragma from different species of snail were similar at a given water content.4.
