A bedding composition for use in sealing insulated glass units to a frame consisting essentially of from 10-50% by weight of a polar solvent or mixture of polar solvents which are substantially insoluble with nonpolar hydrocarbon compounds and which contain elements or functional groups other than carbon and hydrogen; from 5-25% by weight of a plasticizer selected from the group consisting of a polar plasticizer containing at least one noncarbon/hydrogen functional group, a polymeric plasticizer, and mixtures thereof; and from 1-30% by weight of an elastomer compatible with said polar solvent and said plasticizer. A bedding composition comprising: 11% nitrile rubber, 2% polychloroprene rubber, 17% benzoate ester plasticizer, 24% methyl ethyl ketone, 10% talc, 18% ground limestone, 16% tackifier, and 2% stabilizer, all percentages by weight.
