It also acts as a mass transfer barrier, inhibiting oxygen from reaching the thermally insulative ablative material. During the intumescence process, the swollen material will also back fill into interstices within the ablative material and char to enhance their strength. The intumescent coating also acts as a moisture barrier to protect the thermally insulative ablative material from ambient elements such as moisture.Type: GrantFiled: December 22, 1999Date of Patent: November 26, 2002Assignee: The Boeing CompanyInventors: Jim L.

Publication number: 20020122880Abstract: A method of making a composite polymer of a molecularly doped polymer. The method includes mixing a liquid polymer precursor with molecular dopant forming a molecularly doped polymer precursor mixture. The molecularly doped polymer precursor mixture is flash evaporated forming a composite vapor. The composite vapor is cryocondensed on a cool substrate forming a composite molecularly doped polymer precursor layer, and the cryocondensed composite molecularly doped polymer precursor layer is cross linked thereby forming a layer of the composite polymer layer of the molecularly doped polymer.Type: ApplicationFiled: April 16, 2001Publication date: September 5, 2002Inventors: John D. Affinito, Peter M. Martin, Gordon L. Graff, Paul E. Burrows, Mark E. Gross, Linda Sapochak

Patent number: 6444718Abstract: Aqueous urea and/or aqueous urea condensate and/or aqueous urea composition may be utilized to fight grass, forest, building, and other flammable organic material by applying it to these flammable organic materials. The aqueous urea and/or aqueous urea condensate and/or aqueous composition may also be incorporated into flammable materials such as solid and foam plastic and natural materials. Aqueous urea composition are produced by adding and mixing carbon auxiliaries, such as phosphorus containing compounds, metal containing compounds that will accelerate carbonization, heat reflector, surfactant and fillers to the aqueous urea.Type: GrantFiled: September 1, 2000Date of Patent: September 3, 2002Inventor: David H.
