Epoxy resin is biocompatible, meaning it is made of non-toxic materials that do not irritate or damage living human tissue and do not cause physiological or immune system reactions. This makes it suitable for use in medical devices, including prosthetics. Epoxy adhesives play an integral role in the design of medical devices. For example, biocompatible epoxy adhesives are used in the fabrication of prosthetics and dental devices, such as intraradicular reinforcement of the dental structure. Additionally, epoxy-based adhesives are used in surgical equipment, including endoscopes, infusion pumps, catheters, and diagnostic probes.
EPO-TEK® medical-grade epoxies are commonly used in healthcare and biotech industries. These epoxies are used in the manufacture of cardiac, ophthalmic, skeletal, and neurological implants, as well as in dental and surgical tools. The biocompatibility of epoxy resins is certified by the United States Pharmacopeia (USP) Class VI testing in North America. This certification ensures that the epoxy is suitable for direct or indirect contact with human patients.
Overall, epoxy resin is a versatile material that is widely used in construction, electronics, and medical industries due to its high strength, durability, and biocompatibility. Its unique properties make it a valuable material for various applications, including prosthetics, dental devices, and surgical equipment.

Frequently asked questions
Epoxy resin is a type of thermosetting plastic that is widely used in construction, electronics, and other industries due to its high strength, durability, and excellent adhesive properties. It is formed by mixing a resin and a hardener in a specific ratio, resulting in a strong and durable bond.
Regular plastics like PET or PVC are typically thermoplastics, which means they can be melted and reshaped multiple times. On the other hand, epoxy resin is a thermosetting plastic, meaning that once it cures and forms a solid polymer structure, it cannot be melted and reshaped. This irreversible curing process creates a permanent and strong bond.
Epoxy resin is commonly used in the construction industry for concrete repairs, waterproofing, grouting, anchoring, and seamless flooring systems. Its advantages include high strength and durability, excellent adhesive properties, resistance to chemicals and moisture, and the ability to withstand moderate temperatures. It also provides a smooth, glossy, and waterproof finish, making it ideal for garages, basements, and patio floors.
