<p>Liquid and extrudable compositions curable to a rubbery solid comprise a liquid thiol terminated polysulfide polymer, a liquid epoxy resin and a liquid amine terminated polymer containing, on the average, from 1.7 to 4 amino groups per molecule and having the general formula Y-@ &lparstr& B &rparstr& @-Y in which each Y is a univalent organic group derived by removal of an amine hydrogen atom from an aliphatic, alicyclic, heterocyclic or aromatic amine containing from 2 to about 20 carbon atoms and at least 2 amino groups and B is a polymeric backbone comprising carbon-carbon linkages. Insulated window units fabricated using such materials possess superior mechanical and dewpoint retention properties.</p> |
