What Hylomar does

Hylomar is a UK-headquartered manufacturer of high-performance sealants and adhesives, originally founded circa 1960 with its flagship non-setting gasketing compound co-developed with Rolls-Royce for aircraft engine sealing. The company operates from its headquarters and main manufacturing facility in Wigan (Hylo House), with wholly-owned subsidiaries in Grevenbroich, Germany (Hylomar GmbH) and Center Point, Texas (Hylomar LLC) serving European and North American markets respectively. Its product portfolio spans nine formulation categories: non-setting gasketing compounds (Universal Blue, M, Aerograde PL32, Aerograde Ultra, Advanced Formulation, LMF, AF Spezial), RTV silicone sealants (Hylosil), anaerobic adhesives (HyloGrip, Gasket 2000/3400), structural adhesives (Hylobond), instant adhesives (Hyloglue), epoxy systems (Tilebond), MS polymers (HyloFlex), semi-hardening compounds (Hylotyte), exhaust assembly products rated to 1000°C, and ancillary cleaners. Aerospace-grade variants are specified by Rolls-Royce, Pratt & Whitney, and NATO, and the company holds ISO 9001, ISO 14001, IATF 16949, and NSF certifications across the 2024–2027 cycle.

The company monetizes through direct, specification-driven B2B sales to OEM manufacturers and industrial customers across automotive, aerospace, white goods, power generation/distribution, electronics (including EV battery applications), and general engineering verticals. Go-to-market is sales-led with technical consultation, supported by participation in industry exhibitions (Automechanika, Hannover Messe, Battery Show Europe, InterBattery, BondExpo), downloadable technical documentation, product demonstration videos, and direct contact channels (phone, email, web forms) from each regional office. No public pricing or revenue figures are disclosed. As of August 2026, Hylomar was acquired by US-listed specialty materials group Chase Corporation from previous owner PHD Industrial Holdings, with employees joining Chase's broad-based ownership program; deal terms were not disclosed.
