Building designers and contractors typically consider substrate materials, building geometry, project conditions, weather conditions, climate, time, and the need for the air barrier to control water vapor when deciding between sheet-applied and fluid-applied air barriers. Let's take a quick look at ...
“BASF has a portfolio in waterborne dispersions, and for fluid-applied air barriers we have four different types of latexes offered in two different areas: vapor permeable and vapor impermeable,” says Murphy. “Not only can our latex achieve permeability with low water absorption, it...

Chenevert (1970a), however, pointed out that the essential factor is the activity of the water in the shale (as determined in the laboratory by the vapor pressure of preserved cores), since it determines the potential swelling pressure, as shown by Eq. (9.8). Therefore, swelling will be ...

an optional annularly-shaped porous material 118 may be disposed in fluid passageway 112. The porous material 118 may contact the inner walls of the nozzle 102 to form a fluid permeable barrier. The purpose of the porous material is to ensure that the fluid such as air in the passageway is...
As a result of the use of a CTFE copolymer as the material of the layer [Q], the fluid transfer member of the invention acquires not only low water vapor permeability and gas barrier properties but also low chemical liquid permeability that has not been observed as a characteristic of PCTFE...
