  • REFRACTORY FOAM
    Publication number: 20240002301
    Abstract: A porous refractory in the K2O—SiO2—B2O3 system is formed by chemical direct foaming by heating to over 600° C., resulting in adherent black or white foam. The foam can function as highly porous thermal insulation, a high or low thermal emissivity surface, as a sealant for deteriorated refractory surfaces, as a filler for pockmarks/holes/gaps or as a bonding agent for parts with large gaps between them.
    Type: Application
    Filed: September 18, 2023
    Publication date: January 4, 2024
    Applicant: ZYP Coatings, Inc.
    Inventors: Cressie E. Holcombe, JR., Patrick J. Ritt, William Brent Webb
