Gelest

What Gelest does

Gelest, Inc. is a Pennsylvania-based specialty chemical company founded in 1991 by Dr. Barry Arkles and currently operating as a wholly owned subsidiary of Mitsubishi Chemical Corporation. The company develops, manufactures, and supplies silanes, silicones, metal-organics, and specialty acrylates (under the BIMAX® brand) for five primary application segments: CASE (coatings, adhesives, sealants, elastomers), microelectronics, medical devices, life science tools and diagnostics, and personal care. Its portfolio includes proprietary sub-brands such as ExSil® ultra-high elongation silicone elastomers (up to 5,000% stretchability, self-healing behavior), BIOSAFE® silicon-based antimicrobial technology, SiQube™ and SiBrid® personal care hybrid silicone fluids, and a new line of precursor chemicals for dry resist EUV lithography produced at a dedicated 50,000-square-foot Morrisville facility opened in May 2025.

The company's revenue model centers on the sale of specialty chemicals at unit pricing across research quantities (grams to kilograms) and commercial volumes, with NET 30 invoice terms and EXW Morrisville, PA pricing. Gelest operates a sales-led go-to-market with direct engagement through sales representatives and technical support teams, supplemented by distribution partnerships—most notably Nordmann for EMEA (effective January 1, 2026) and India. For advanced technology segments such as semiconductor EUV lithography, Gelest engages in enterprise-level field sales, evidenced by a 2026 research agreement with IBM to test precursors in High NA EUV processes, and a 2022 collaboration with Lam Research and Entegris announced at SEMICON WEST.

Gelest is led by President Dr. Jonathan Goff (Ph.D., Macromolecular Science and Engineering, Virginia Tech; 60+ patents), with Edward Kimble as Executive Vice President, William Fry as CFO, and Dr. Santy Sulaiman as VP of Research & Development. The company operates two European subsidiaries—Livchem Logistics (Germany) and Bimax Chemicals Limited (UK)—supporting regional logistics and distribution, and does not appear to have received external venture capital or private equity funding.
