Dymax Corp. has added the new 1040-M to its MD line of adhesives for medical device assembly applications. Developed to be autoclave resistant for more than 100 cycles, MD 1040-M offers low water absorption (0.5%), suiting it for surgical tools and devices that are subjected to numerous instances of sterilization, including autoclave or STERRAD (plasma), the company shared in a news release. The adhesive can also serve as an encapsulant to protect critical sensors and electronic components, where moisture ingression may be of concern.
MD 1040-M cures quickly upon exposure to broad-spectrum UV light and is optimized to be LED curable at 365 nm wavelength, the company reported. It can bond to a variety of substrates including stainless steel, aluminum, glass, PP/PE, and PCB, and it can encapsulate RFID chips, sensors, and other electronic components. Other uses include a variety of medical scopes and dental equipment.
1040-M meets the requirements for ISO 10993-5 cytotoxicity, is formulated without IBOA, has a durometer hardness of D60, and viscosity of 775 cP, Dymax reported. The adhesive is solvent free and RoHS compliant, positioning it as a “greener” choice over comparable one- and two-part solvent-based epoxies currently on the market, the company stated.
