Heat-resistant composite materials / heat-resistant adhesive "Skybond"
Skybond is a varnish based on the most thermally stable aromatic polyimide. It was developed by Monsanto in the United States, and I.S.T acquired the manufacturing and sales rights in April 1996, producing it at the Monsanto Indian Orchard plant in Massachusetts. However, in 2014, the plant was relocated, and it is now produced at the I.S.T New Jersey plant. Skybond can form extremely excellent polyimide prepregs and honeycombs with high thermal resistance and flexibility by combining with high-strength heat-resistant fibers such as glass fibers, carbon fibers, and aramid fibers. It can also be used as a heat-resistant adhesive and sealant. Its applications are mainly in the aerospace field, used in aircraft structural materials, jet engine covers, and wing components. Additionally, taking advantage of its excellent heat resistance, it is used as insulation covers for structures and engines that operate at high temperatures. Heat-resistant bearings and bushes utilizing powder molding properties are also used in a wide range of fields, including office automation equipment. The resin's exceptionally high thermal stability, mechanical and electrical properties, and high reliability are backed by years of proven performance, and its applications continue to expand into aircraft and industrial equipment.
