Anchor-Seal

What Anchor-Seal does

Anchor-Seal, Inc. is a privately held Massachusetts corporation founded in 1979 and headquartered at 54 Great Republic Drive, Gloucester, MA. The company custom-formulates and manufactures high-performance thermoset materials — specifically epoxy encapsulation systems, polyurethane elastomers (Shore A flexible, Shore D rigid, and water-clear aliphatic), polyureas, and RTV-2 silicone rubber compounds (Tin and Platinum series). These materials are engineered for challenging production requirements including dimensional stability, heat and chemical resistance, low shrinkage, impact resistance, optical clarity, and deep-section cure behavior, and are sold into potting/encapsulation, adhesives, sealants, casting resins, mold making, prototyping, and surface coating applications.

The company serves a diversified industrial customer base across at least five vertical segments: industrial manufacturing, medical and healthcare (including prosthetics), electronics, construction and marine, and entertainment/special effects (including animatronics). Referenceable engagements include supplying materials used in Disney animatronic skin applications and components for the prosthetics market serving military veterans. Anchor-Seal also operates as a New England distributor for Silicones, Inc. RTV-2 products and distributes Solvay Chemicals' EPA-registered Proxitane AHC disinfectant (5-gallon pails), and offers private white labeling of epoxy, urethane, and polyurea products for retail brands. Supplementary products include pigment dispersions, mold release agents, and dry gas blanket shelf-life extenders.

Revenue is generated primarily through direct sales (phone, email, contact form, and a recently launched e-commerce storefront for disinfectant products) on a quote-based pricing model for custom-formulated materials, with publicly disclosed unit pricing only on the Proxitane AHC disinfectant. Marketing channels are limited to a company website, an organic Facebook page, and earned media (Fox Business Network's Manufacturing Marvels feature in 2022). The company demonstrated operational flexibility in 2020 by pivoting to hand sanitizer production during COVID-19. Leadership comprises CEO Pete Spinney (noted in 2011), with no disclosed board, institutional investors, or active funding activity; ownership appears closely held.
