What Cotronics does
Cotronics Corp is a privately held, Brooklyn-based specialty manufacturer founded in 1971 that produces high-temperature ceramic and epoxy adhesive materials for industrial, electronics, and laboratory applications. The company's product portfolio spans five core categories — Resbond Epoxy Adhesives, Ceramic Adhesives, Ceramic Materials (castable, machinable, and potting), Flexible Ceramics (blankets, boards, papers, sleeving, tapes), and Repair Materials — sold under six proprietary sub-brands (Durabond, Resbond, Durapot, Rescor, Thermeez, Ultra Temp). Differentiated technical features include formulations rated up to 4000°F, room-temperature curing options that eliminate the need for specialized equipment, machinable ceramics workable with standard shop tools, and metallic composite adhesives designed for dissimilar material bonding up to 2000°F. Most products are described as asbestos-free and low-VOC, with custom formulations available on request.
The business operates a direct-to-customer model: orders are taken by phone, fax, email, or website order form, with products shipped from the single Brooklyn headquarters at 131 47th Street. Pricing is unit-based and not publicly disclosed (the current catalog is explicitly marked 'NO PRICES'), with quotes generated on a pay-as-you-go basis. Marketing is limited to downloadable catalogs and product data sheets on the company's website, which is maintained by a third-party vendor (NST Web Solutions). The firm is independently owned with no venture capital, private equity, or institutional investment indicated, and serves industrial manufacturers, electronics/electrical equipment producers, and research laboratories primarily in the Northeast US, with no global footprint claim. With 11–50 employees and no disclosed revenue, Cotronics appears to be a stable, owner-operated niche manufacturer sustained by long-tenured product lines and specialty temperature-performance positioning rather than scale-driven growth.
