What FMi Chemical does

FMi Chemical is a Connecticut-based, specialty manufacturer and distributor of nonmetallic aerospace sealants, compounds, and coatings serving jet engine OEMs, airframe manufacturers, and MRO (Maintenance, Repair, and Overhaul) facilities. Founded in 1987 and headquartered in Bloomfield, CT, the company focuses on heat-resistant RTV-2 silicone chemistries for high-temperature applications such as abradable air seals in turbine blade channels and potting/damping compounds in low-pressure compressor stator vanes. Its proprietary Thermosil product line (T7000, 4000, 3005, 3002, 3006) is qualified to the specification systems of leading engine OEMs including Pratt & Whitney (PWA 407, PWA 404-2, PWA 36723-1), GE Aviation (A15F18A1/B1), and Honeywell (EMS53163 Type 1&2), with Thermosil T7000 rated to 525°F. The company also operates as an authorized distributor for third-party aerospace chemical brands from Dow (Dowsil, Molykote), Henkel (Loctite), Hexion (Epon, Epikure), Cytec, Everlube, Permabond, 3M, and others.

Underlying technology centers on proprietary microsphere surface treatment and glass-polymer matrix chemistry for abradable sealants, paired with void-free pre-measured injection cartridge systems that eliminate air pockets in sealed components. The Thermosil portfolio is supplemented by an in-house Nadcap- and ANAB ISO/IEC 17025:2017-accredited laboratory that operates as Pratt & Whitney's Laboratory Control at Source (LCS) and GE's S-450 certified lab, supporting both internal R&D and external testing/repackaging services. The company maintains AS9100D + ISO 9001:2015 quality certifications and emphasizes batch traceability and short lead times as operational differentiators.

Revenue is generated through one-time product sales of proprietary and distributed aerospace chemicals plus three service lines: (1) accredited laboratory testing including recertification programs that extend material shelf-life, (2) custom repackaging into application-ready configurations from 2.5 oz injection cartridges to multi-gallon pails, and (3) epoxy adhesive roll slitting services with on-site cold storage. Go-to-market is enterprise-direct field sales via phone and website inquiry, targeting aerospace procurement and MRO supply chains. In 2024, Novaria Group, an aerospace/defense chemicals and materials holding company, announced an acquisition agreement under which FMi Chemical now operates as a division.
