Linde Advanced Material Technologies Inc.

Linde Advanced Material Technologies Inc., doing business as Praxair, a foreign-owned manufacturer of advanced materials, thermal spray equipment, and specialized powders, operates as a prime contractor delivering physical goods and maintenance services to the Department of Defense, NASA, and the Navy across 45 federal agencies with no small-business set-aside positioning. The company competes in full-and-open procurements and holds no SBA certifications; it is a subsidiary of Linde Inc., headquartered in Danbury, Connecticut, and is classified under multiple NAICS codes spanning adhesive manufacturing, aircraft parts and auxiliary equipment manufacturing, and aircraft engine parts manufacturing.

Praxair's federal footprint centers on three capability areas grounded in recent awards: specialized additive manufacturing powders (GRX-810, HR-2, environmental barrier coating powders), thermal spray equipment maintenance and calibration, and high-temperature coating materials for aerospace and defense applications. Representative prime awards include a $168.75 million sole-source purchase order from NASA Shared Services Center in June 2022 for GRX-810 powder to support metallurgical testing and fatigue studies for lunar and Mars missions; a $279.138 million indefinite delivery contract with the Department of the Air Force Materiel Command Ogden Air Logistics Complex running through March 2026 for thermal spray equipment service, calibration, emergency maintenance, and parts supporting the 309th Maintenance Support Squadron at Hill Air Force Base, Utah; and a $127.844 million purchase order from NASA Shared Services Center in May 2024 for additive manufacturing powders supporting NASA's research laboratories.

Customer concentration splits sharply between volume and dollar value. By award count, the Department of the Air Force dominates with 146 awards accounting for 59% of all awards, followed by Naval Air Systems Command (81 awards) and the Air Force Materiel Command (62 awards). By potential value, however, Air Force Materiel Command Oklahoma City Air Logistics Complex commands $5.4 million across just five awards, NASA Shared Services Center carries $1.3 million across 25 awards, and the Air Force Materiel Command Ogden Air Logistics Complex represents $782 thousand across ten awards — signaling that Praxair's high-dollar awards cluster in Oklahoma City and Ogden, while maintaining a broad, low-dollar transactional relationship with multiple Navy and Air Force depots. Combined potential value across all 603 awards in the source data totals $9.2 million, though obligated dollars ($25.3 million) exceed this figure, indicating older or closed awards in the portfolio.

The top parent vehicle is an indefinite delivery contract (M0014603D9008) with 72 task orders and $779 thousand in combined potential value, likely supporting recurring maintenance and supply demand at Hill Air Force Base. Four additional Air Force IDVs (FA810404D0012, F3460199D0128, F4160898D0686, F3460198D0154) carry between 14 and 21 task orders each, with the second generating $59 thousand in combined value. Recompete exposure is minimal — only one award ($63 thousand) completes within the next twenty-four months.

In its subcontractor role, Praxair delivers specialized processing and materials supply to Moog Military Aircraft LLC (multiple awards for electrochemical machining of V-22 platform actuators as outside processing since January 2026), Moog Inc. (electrochemical machining of electromechanical actuators, dating to March 2025), Honeywell International Inc. (TIGER III powder delivery per specification, January 2026), and University of Dayton (materials, engineering services, and sustainment support for advanced manufacturing programs under SABR-C and EPSE initiatives, spanning 2022 through October 2025). Praxair also supplied materials for Air Force Research Lab work on large-scale additive manufacturing for hypersonics through Spirit AeroSystems in May 2023.

Activity has grown unevenly — eight awards in 2022, ten in 2023, dropping to four in 2024, then spiking to twenty in 2025 and six in the first quarter of 2026. The surge in 2025 reflects both an influx of subcontract work under Moog primes and sustained NASA and Air Force maintenance demand. With 96% of awards as a prime versus 4% as a subcontractor, Praxair's business model emphasizes direct-sale manufacturing and logistics rather than teaming arrangements, positioning the company as a sole-source supplier of specialized powders and a captive maintenance provider for its own thermal spray equipment at critical Air Force depots.
