International Classification:

C08G 7500

US Classification:

525535, 528373, 528374, 528378

Abstract:

A blend of multimodal average molecular weight sulfur or ether linkage containing organic polymers provides sealants, potting compounds and moldable compositions with good physical properties. In the case of S-containing polythioether or polysulfide, these properties are well suited to the formulation of aerospace sealants even using standard lightweight filler technology. Sealants based upon this multimodal blend concept exhibit improved strength and toughness even when relatively large amounts of lightweight fillers are used. Multimodal polyurethanes and other ether linkage containing polymers also show enhanced physical properties.

Abstract:

In the vertical corner transition arrangement for semi-membrane tanks disclosed in the specification, curved horizontal sides plate of a semi-membrane tank wall are welded to one side of a vertical extruded aluminum modified I-beam with a vertical tapered stiffening corner block projection on the opposite side of the extruded aluminum I-beam, and the edge of a vertical unstiffened curved cylinder section is butt-welded to the projecting edge of the vertical tapered stiffening corner block. The curved plates of an orthogonally oriented semi-membrane tank wall are welded to one side of another vertical extruded I-beam member having a projecting vertical tapered stiffening corner block welded to the opposite side with a projecting edge which is welded to the opposite edge of the vertical stiffened curved cylinder section to complete the corner of the tank.
