Abstract: An insulating glass unit including a first pane of glass, a second pane of glass, and a spacer system. The spacer system includes (i) a spacer positioned between an inner surface of the first pane of glass and an inner surface of the second pane of glass and (ii) a sealant system for adhering the inner surfaces of the glass panes to the spacer. The sealant system includes at least one sealant having (a) at least one thermoplastic hot-melt material having a melt temperature ranging from about 125null F. (51null C.) to about 250null F. (121null C.), and (b) at least one curable material. The sealant, when cured, forms a covalent bond between the spacer and the panes. The sealant has an initial hardness ranging from about 25 Shore A to about 450 Shore A and a post-cure hardness measured about 48 hours thereafter ranging from about 30 Shore A to about 50 Shore A.

Abstract: The present invention relates to the use of cycloaliphatic diamines as cosolvents for hydrophobic amines in aqueous solution. The cycloaliphatic diamines of the present invention have a formula: 1 where n is 1 or 2, each R is independently selected from a group consisting of: hydrogen, a 1 to 6 carbon aliphatic, and a 0 to 6 carbon containing amine, wherein each R is chosen such that the cosolvent amine comprises at least two amine groups; and a quantity of water to maintain said solution as a homogeneous phase. The cosolvent diatines have particular utility in the formation of water based epoxy resin curing agents. Superior water miscibility is achieved for hydrophobic amines through the use of cycloaliphatic amines as compared to conventional cosolvents.

Abstract: Methods for treating a substrate are disclosed. The substrate is deoxidized and then immersed in an electrodepositable pretreatment composition comprising a lanthanide series element and/or a Group IIIB metal, an oxidizing agent, and a metal-complexing agent to deposit a coating from the electrodepositable pretreatment composition onto a surface of the substrate. Optionally, the electrodepositable pretreatment composition may comprise a surfactant. A coating from a spontaneously depositable pretreatment composition comprising a Group IIIB and/or Group IVB metal may be deposited on the substrate surface prior to electrodepositing a coating from the electrodepositable pretreatment composition. Following electrodeposition of the electrodepositable pretreatment composition, the substrate optionally may be contacted with a sealing composition comprising phosphate and a Group IIIB and/or IVB metal. Substrates treated according to the methods also are disclosed.
