HIGHLIGHTS

SKYBOND is a varnish that is composed of aromatic polyimides, which are one of the most thermally stable organic materials. The products originally developed by Monsanto(USA) are polymide precursors which, when properly cured, yield composites and adhesives with the highest thermal stability of any commercially available resin system. In April 1996, I.S.T acquired the right of manufacture and sales of the varnish. After acquiring SKYBOND, it was manufactured at our I.S.T factory on the premises of Solutia's Indian Orchard plant in Massachusetts. In 2014 we moved SKYBOND® plant to I.S.T New Jersey factory(inside DuPont) and now we are manufacturing SKYBOND in there. Polyimide prepreg or honeycomb composite materials can be made combining SKYBOND with glass, carbon, or aramid fibers, that have superb thermal-resistance and flexibility. In addition the varnish is used as a thermal-resistant adhesive material or sealing agent. SKYBOND is applied mainly to airplane structural materials, jet engine covers, and aerofoils in the aerospace. It is also applied to heat-resistant covers for structures and engines used under high-temperature conditions, making use of its excellent heat resistance. In addition, with its powder molding property, SKYBOND is applied to heat-resistant bearings or bushings, which have been introduced in various fields, such as office automation equipment. Two new classes of matrix resins have been developed in the Skybond® family. The first can be processed by RTM molding techniques to bring the outstanding thermal resistance of polyimide resins to RTM molded composites. The second new class of Skybond® matrix resins is the two-stage cure resins that when used in prepreg applications allow the manufacture of very low void level composites by autoclave processing (<0.5% voids) combined with the excellent thermal stability of polyimide resins.
