Moisture permeability of mature concrete, cement mortar and cement paste
Moisture permeability tests were performed on specimens of concrete, cement mortar and cement paste with the bottom side in water or in moist air and the upper side in a relative humidity of 33 %. The distribution of the relative humidity within the specimen was measured, at stationary conditions, …

An experimental apparatus for the measurement of moisture permeability of building materials
… was built and operated for the measurement of moisture permeability of building materials. The data are for use in resolution of problems associated with moisture buildup in porous building materials. The apparatus is capable of maintaining simultaneous humidity and temperature differences …

DEVELOPMENT AND IN-SITU CHARACTERIZATION OF BI-LAYERED LAMINATED COMPOSITES FOR ENHANCED MOISTURE BARRIER PERFORMANCE
… resistance. However, silicone is susceptible to moisture-induced failures due to high moisture permeability. This study mainly focuses on improving the moisture ingression characteristics of the silicone encapsulation by adding a polyurethane moisture barrier layer. This study focuses on the …

Moisture transfer in porous materials exposed to combined humidity and temperature gradients
Moisture migration is responsible for much damage in modern buildings. Air infiltrations were almost eliminated because of the use of various qualities of materials and insulation. Water is mainly transferred through building materials by diffusion, under three different phases (vapor, liquid and …

HYGROTHERMALLY-INDUCED DELAMINATION AND CRACKING IN PLASTIC IC PACKAGES
Plastic-encapsulated packages are susceptible to moisture-induced cracking due to high moisture permeability of the typical epoxy molding compound. During solder reflow, the high temperature together with the previously absorbed moisture will result in high hygrothermal stresses at material …

Scalable corrosion resistant coatings for thermal applications
… due to their high dielectric breakdown and low moisture permeability. However, their application to arbitrarily shaped metals is difficult or expensive. Here, we develop a sol-gel solution capable of facile and controllable dip coating on arbitrary metals, resulting in a very smooth (< 5 nm …
