First Claim
Patent Images
1. An insulated glass unit comprising at least two spaced-apart sheets of glass in spaced relationship to each other, a low thermal conductivity insulating gas or mixture of gases therebetween and a gas sealant element including a cured sealant composition resulting from the curing of a curable sealant composition comprising:
- a) at least one silanol-terminated diorganopolysiloxane;
b) at least one crosslinker for the silanol-terminated diorganopolysiloxane(s);
c) at least one catalyst for the crosslinking reaction;
d) at least one organic nanoclay; and
, optionally, e) at least one solid polymer having a permeability to gas that is less than the permeability of the crosslinked diorganopolysiloxane(s).
