Patent number: 5108832Abstract: Disclosed is an intumescent curable composition which contains as a resinous binder a flexible polyepoxide resin. The polyepoxide is cured with an appropriate curing agent adapted for the particular resin. An additive component is present which contains a mixture of materials which provide a source of(i) zinc,(ii) boron,(iii) phosphorus, and(iv) an expansion gas upon thermal decomposition. The composition is capable of forming a carbonaceous char upon exposure to heat or flame, with the proviso that the cured, unburned composition has sufficient flexibility that is passes at least 10 continuous cycles of a cold cycle test without cracking. The cold cycle test involves the following steps: the composition is applied at a thickness of 0.5 inch (12.7 millimeters) to a 10 inch (0.0254 meter) section of a 4W13 I-beam having two thermocouples attached to the surface, allowed to cure at ambient temperature for 16 hours, force cured for 5 days at about 60.degree. C. and subjected to the cold cycle test.Type: GrantFiled: September 28, 1990Date of Patent: April 28, 1992Assignee: PPG Industries, Inc.Inventors: Richard M. Nugent, Jr., Thomas A. Ward, Paul P. Greigger, Jerome A. Seiner
