Abstract
The invention relates to a high thermal efficiency, insulated glass unit structure sealed with a cured composition containing, inter alia, moisture-curable silylated resin, the cured composition exhibiting low permeability to gas(es).
Claims21
An insulated glass unit comprising at least two spaced-apart sheets of glass, or other functionally equivalent material, in spaced relationship to each other, a low thermal conductivity gas or mixture of gases therebetween and a gas sealant element including a cured sealant composition resulting from the curing of, moisture-curable silylated resin-containing composition comprising:
- a) moisture-curable silylated resin, which upon curing, provides cured resin, exhibiting permeability to gas;
- and,
- b) at least one other polymer having a permeability to gas that is less than the permeability of cured resin (a), and, optionally,
- c) at least one additional component selected from the group consisting of filler, adhesion promoter, catalyst, surfactant, UV stabilizer, antioxidant, cure accelerator, thixotropic agent, moisture scavenger, pigment, dye, solvent and biocide.
