Master Bond

When design engineers face the challenge of bonding dissimilar materials — composites, engineering plastics, metals, and ceramics — Master Bond delivers polymer systems engineered to perform where conventional fasteners fall short.

Founded more than 50 years ago, Master Bond has grown into a leading formulator and manufacturer of high-performance adhesives, sealants, coatings, and potting/encapsulation compounds. Its product line spans more than 3,000 grades of epoxy, silicone, UV-curable, and other specialty systems, giving engineers in aerospace, automotive, electronics, medical devices, and renewable energy a broad toolkit for demanding applications.

For engineers working with composites and plastics, the company's structural epoxy adhesives distribute stress evenly across bonded joints — reducing fatigue-inducing stress concentrations — while simultaneously sealing the interface. Select formulations bond reliably to polycarbonates, acrylics, and other engineering thermoplastics, as well as to carbon fiber, fiberglass, and hybrid composite structures. Select grades offer a wide variety of performance properties including service temperature ranges from cryogenic to 600°F, thermal conductivity, chemical resistance, low outgassing, outstanding bond strength and more.

Master Bond's compounds comply with a wide range of industry certifications, including NASA low-outgassing specifications, UL 94V-0 for flame retardancy, RoHS compliance, and FDA, USP Class VI, and ISO 10993-5|10 standards — critical for end-use environments where material qualification is crucial.

Every inquiry is assigned to a dedicated technical representative who supports customers from early design through prototyping and full-scale production. Moreover, every formulation is made to order, ensuring optimal performance and extended shelf life. Products ship directly from Master Bond's U.S. manufacturing facility in quantities ranging from single-gram syringes to multi-gallon production containers.
