How to select the right medical adhesive Picking the right adhesive almost always entails a balancing act as engineers attempt to find products that meet conflicting end-use and manufacturability requirements. Medical device engineers, who also have to contend with a strict regulatory environment, often have the toughest time striking that balance. Like engineers in less regulated industries, device engineers have to contend with difficult application requirements—such as high bond strength, thermal performance and chemical resistance. On top of these challenges, they have the added burden of...

This compound provides very good toughness with a high elongation of 50-60%. It is capable of withstanding many chemicals including liquid sterilants, antimicrobial agents, ethylene oxide (EtO), e-beam,...

See UV17Med in action in this video demonstration WATCH NOW What biocompatibility tests can be performed on an adhesive, to be considered for use in a medical device applications? It is important to not only be aware of the location of the adhesive, sealant, or encapsulant within the medical device but also the nature of the medical device in question. As a rule of thumb, in choosing such compounds, the adhesive must exhibit non-leaching characteristics. Biocompatibility is of utmost importance when there is skin or body contact involved, while in some non-contact type applications, this biocompatibility...

ISO 10993-5 test on the other hand involves non-cytotoxic deterministic procedures. The USP Class VI test is conducted by producing an extract of the product in sodium chloride, alcohol, polyethylene glycol, and vegetable oil. These are also injected in specimens, so that the biological response to the extracts can be observed. The Acute Systemic Toxicity (Systemic Injection) Test measures the toxicity and irritation when a sample of the compound is administered orally, applied to the skin, and inhaled. The Intracutaneous Test measures toxicity and localized irritation (between the skin) when...

• High temperature resistant • Superior chemical resistance to acids, bases and many solvents • Withstands 100 cycles of many sterilization methods • Long working life at room temperatures This graph displays the autoclave resistance of a casting of EP62-1Med, roughly 2 inches in diameter, and 0.125 inches thick. The casting was then subjected to multiple autoclaving cycles up to 100 cycles. Each autoclave cycle was around 20 minutes at 250°F (~121°C) and about 15 psi of steam pressure. The weight change was then measured periodically. Also included is a reference epoxy, which shows much more...

EP3HTMed is formulated to cure rapidly at elevated temperatures. It has excellent resistance to multiple cycles of radiation, EtO, autoclaving and chemical sterilants. Its service operating temperature range is -60°F to +400°F. Another benefit of this single component, no mix epoxy adhesive is its unlimited working life. • Superb resistance to autoclaving, chemical sterilants, radiation and EtO • Excellent adhesion to many substrates Video Testimonial: Liger Medical Master Bond worked one-on-one with Liger Medical to meet their specific assembly and use requirements. After thoroughly reviewing...
