Interphase Materials, Inc.

Interphase Materials, Inc., doing business as Biointerphase, Inc., is a for-profit manufacturer of advanced materials and specialized coatings based in Pittsburgh, Pennsylvania, that develops PFAS-free omniphobic coatings, biomaterials, and sensor technologies for federal defense and civilian agencies exclusively as a prime contractor under total small business set-asides. The company has no subcontract footprint and operates entirely on SBIR, STTR, and definitive small-business contracts.

Interphase's capability portfolio centers on materials science and surface-chemistry innovation. Representative recent work includes a $1.36 million Army definitive contract (June 2026, completion June 2028) for development of a next-generation PFAS-free omniphobic coating platform engineered for military textiles, a December 2024 STTR Phase I contract from Army Research, Development and Engineering Command valued at $203,891 to develop biosynthetic omniphobic technologies for DoD clothing and equipment without fluorine or perfluorinated compounds, and a $499,587 Army Corps of Engineers definitive contract (September 2025) to develop a biomaterial designed to improve cooling efficiency and resilience of Army facilities. The company also received a $641,446 Department of Transportation SBIR Phase II award (September 2022, completed September 2024) on AI-driven inspection and sanitization of transit vehicles, and a $239,793 Naval Sea Systems Command STTR Phase I contract (July 2023) for fouling-prevention and corrosion-resistance coatings. Grant work includes a Bureau of Reclamation cooperative agreement (June 2022 through December 2023) focused on preventing biofouling on reverse-osmosis membranes through biomaterial coatings and real-time biofilm-monitoring systems for desalination plants.

Customer concentration splits across defense and transportation. Naval Sea Systems Command, Army DEVCOM, and the Army overall together represent 73% of recent awards by count and 99% by combined potential value. The Department of Transportation holds three awards but lower dollar volume ($989 thousand), while the Office of the Secretary of Defense and Bureau of Reclamation each hold one award. Activity has remained modest — fifteen total awards across nine distinct federal agencies over the source period, with two awards (combined potential value $1.9 million) reaching completion inside the next twenty-four months and therefore facing recompete exposure. All fifteen prime awards carry total small-business set-aside designations. The majority of work maps to NAICS 541712 (Research and Development in the Physical, Engineering, and Life Sciences) and centers on advanced materials development, sensor integration, and environmental-performance innovation for military textiles, facility infrastructure, and water-treatment applications.
