Appl. No.:

7/172560

Inventors:

John McShane - North Hollywood CA

Assignee:

Products Research & Chemical Corp. - Glendale CA

International Classification:

E06B 366

US Classification:

428 34

Abstract:

A multi-pane thermally construction in which one or more chambers are provided by two or more spaced argon gas and permeable transparent panes are filled with argon gas, said panes having inner edge margins, which includes the combination of: spacing means for spacing said means at said inner edge margins, and a seal having low permeability to argon gas between said spacing means and each of said inner edge margins, said seal comprising a solid elastomer of a cured polymer composition composed of thioether mercaptan terminated disulfide polymer of the formula HS(RSS). sub. m R'SH; (b) from about 10 mole percent to about 75 mole percent of diethyl formal mercaptan terminated polysulfide polymer of the formula HS(RSS). sub. n RSH; wherein in the formulae R is --C. sub. 2 H. sub. 4 --O--CH. sub. 2 H. sub.

Abstract:

A method for substantially preventing the escape of argon gas from a chamber defined by two window panes in spaced relation and spacing means between the inner edge surface portions of the window pane by: forming a seal at the edge portions of the spacing means of a liquid polymer composition composed of (a) from about 90 mole percent to about 25 mole percent of thioether mercaptan terminated disulfide polymer of the formula HS(RSS). sub. m R'SH; (b) from about 10 mole percent to about 75 mole percent of diethyl formal mercaptan terminated polysulfide polymer of the formula HS(RSS). sub. n RSH; wherein in the formulae R is --C. sub. 2 H. sub. 4 --O--CH. sub. 2 H. sub. 4 --; R' is alkyl thioether of from 4 to 20 carbon atoms and the value of m and n is such that the diethyl formal mercaptan terminated polysulfide and the thioether mercaptan terminated disulfide polymer have an average molecular weight of between about 1000 and about 4000; and (c) a curing effective amount of a curing agent; curing said liquid polymer composition to a solid elastomer which is substantially impervious to argon gas; and filling the chamber with argon gas.
