What RELTEK does
RELTEK LLC is a specialty chemical manufacturer founded in 1996 by Robert E. Lindberg and headquartered in Santa Rosa, California. The company formulates and manufactures high-performance adhesives, sealants, and coatings sold under the BONDiT brand, with the core value proposition being reliable bonding of difficult substrates—including fluoropolymers, polyolefins, and dissimilar material combinations—in harsh environments where conventional adhesives fail, such as cathodic seawater, downhole oil, and high-temperature electronics. The product portfolio is organized into two families: B-series two-part epoxy adhesives (B-45, B-46, B-481, B-4811, B-482, B-4682, B-521, B-536, B-755) covering potting, conformal coating, and structural bonding from -50°F to 600°F, and A/C-series primers and adhesion promoters (A-3, A-43, A-46, C-6, C-52) that prepare substrates for the B-series. Differentiated technical assets include proprietary Accelerated Life Testing (ALT) capability that compresses qualification cycles, and a PTFE bonding kit combining fluoropolymer etchant with BONDiT adhesives for surfaces previously considered un-bondable.
RELTEK primarily serves defense, marine/subsea, oil & gas, electrical/electronics, and industrial customers. Named end users include U.S. Navy programs (submarine polymer-to-metal bonding, sonar cable assemblies), a Canadian defense contractor, major U.S. and European cable companies (17,000 PSI deep-sea fiber optic terminations with 20-year life ratings), an offshore oil equipment supplier, and BIW Connector Systems. The company emphasizes long qualification cycles and 20+ year customer tenures, indicating mission-critical use cases where revalidation costs deter supplier switching.
The business model combines factory-direct sales (minimum order $100 USD, with technical support) and a multi-tier distribution network: U.S. stocking distributors (McMaster Carr, Amazon), U.S. non-stocking distributors (Ellsworth, Port Plastics, Laird Plastics, Grainger, Fastenal), and a China stocking distributor (Duncotek, a Sino-Resource Group subsidiary). Revenue derives from one-time product sales (sample kits $100–$200, cartridges, bulk containers) and bundled engineering/consulting services. Pricing is transparent and publicly disclosed, with a 2023 price increase noted on the company website. The company is ISO 9001:2015 certified and remains privately held under founder ownership with no disclosed external funding.

RELTEK product offering
Product offeringCore offering
RELTEK manufactures and sells a proprietary line of adhesives, sealants, and coatings marketed under the BONDiT brand. The products are engineered for harsh-environment bonding applications on hard-to-bond substrates including metals, plastics, glass, ceramics, rubbers, and dissimilar material combinations used in industrial, defense, marine, oil and gas, and electronics applications.
Product overview
RELTEK manufactures and distributes adhesives, sealants, and coatings for hard-to-bond substrates and harsh environments. The product portfolio centers on the BONDiT brand family of polymer bonding systems, which includes two primary product lines: the B-series epoxy adhesives (B-45, B-46, B-481, B-4811, B-482, B-4682, B-521, B-536, B-755) which serve as the core adhesive, sealant, potting and coating formulations, and the A/C-series primers and adhesion promoters (A-3, A-43, A-46, C-6, C-52) which prepare surfaces for optimal bonding. The B-series products are two-part epoxy systems offered in various configurations (2:1, 1:1, 10:1, 4:1 mix ratios) for applications ranging from flexible coatings to rigid potting. RELTEK also offers specialized kits including PTFE Bonding Kits for fluoropolymer surfaces, Splice Kits for cable termination, and Technology Assessment Kits for product testing. These products are designed for bonding difficult substrates and dissimilar materials in military, marine, oil & gas, electronics, and industrial applications.

RELTEK competitors and assessment
Company assessmentBroad incumbents
- H.B. Fuller: Global industrial adhesive manufacturer serving packaging, hygiene, construction and durable-goods markets. Overlaps with RELTEK in specialty structural adhesives and sealants but operates at vastly greater scale across mainstream industrial accounts.
- ITW (Devcon / Permatex): Diversified industrial manufacturer whose Devcon brand supplies epoxy adhesives, coatings and repair compounds for MRO and production. Adjacent competitor to RELTEK in industrial two-part epoxies and sealants.
- 3M: Diversified industrial conglomerate with extensive adhesive, sealant and coating lines (including structural, epoxy, and pressure-sensitive ranges). Competes with RELTEK broadly across industrial, electronics and defense customers but at much larger scale.
- Bostik (Arkema): Arkema-owned global adhesives business with strong positions in industrial, construction and packaging bonding. Comparable to RELTEK in adhesive chemistry but competing primarily in high-volume categories rather than niche harsh-environment formulations.
- Henkel (Loctite): Global leader in industrial adhesives, sealants and functional coatings through its Loctite brand; dominates the structural and instant-adhesive segments. Sizable overlap with RELTEK's adhesive technology, though offering a far broader portfolio at commodity scale.
Direct peers
- Ellsworth Adhesives: Specialty adhesives distributor and formulator (parent of ResinLab) selling epoxy, silicone and urethane systems to industrial, electronics and defense OEMs. Directly competes with RELTEK via shared distribution channels and overlapping product chemistry.
- Permabond Engineering Adhesives: Specialty manufacturer of structural cyanoacrylate, epoxy and UV-cure adhesives for industrial and defense applications. Comparable to RELTEK in formulation-driven differentiation and engineered bonding solutions for difficult substrates.
- Dymax Corporation: Specialty formulator of light-cure, epoxy and structural adhesives with harsh-environment electronics and medical applications. Overlaps with RELTEK on potting compounds, conformal coatings and engineered bonding systems for regulated markets.
- Epoxy Technology Inc. (EPO-TEK): Specialty epoxy and adhesive manufacturer serving semiconductor, electronics, optics and medical device markets. Comparable niche model to RELTEK with high-performance, application-specific formulations sold technical-direct.
- Master Bond Inc. U.S. specialty formulator of epoxies, silicones, UV-curable and potting systems for harsh-environment electronics, aerospace and defense applications. Closely comparable to RELTEK in product mix (epoxy adhesives, sealants, potting compounds) and customer segments (military, aerospace, subsea, oil & gas).
