Master Bond has announced the release of its new product, EP41S-5Med. The two part epoxy system features a high temperature resistance and is electrically insulative, therefore making it suitable to be utilised in medical electronic applications.
EP41S meets the requirements of ISO 10993-5 for non-cytotoxicity and can be used for bonding, sealing, and coating in medical devices. This epoxy was tested against many sterilisation methods, such as autoclaving, STERRAD®, Cidex® and Steris®, successfully resisting a hundred cycles. It is also capable of withstanding exposure to gamma radiation, ethylene oxide, as well as other aggressive sterilants and chemicals.
The new epoxy provides a tensile strength of 10,000 psi – 12,000 psi and adheres well to a variety of similar and dissimilar substrates, including metals, plastics, rubbers, ceramics, and composites. The compound has a glass transition temperature of 140°C – 145°C and is serviceable from -80°F to +450°F (-62°C to +232°C). EP41S-5Med also features reliable electrical insulation characteristics with a dielectric constant of 3.5 at 60 Hz and a volume resistivity greater than 1014 ohm-cm.
EP41S is black in colour and contains no solvents or diluents. EP41S-5Med also offers convenient handling with a 100 to 25 mix ratio by weight. The mixed epoxy has good flow properties with a moderate viscosity of 25,000 cps – 30,000 cps. Upon cure, it offers low shrinkage and a hardness of 85 – 95 Shore D.
EP41S-5Med comes in standard sized units of ½ pint, pint, quart, and gallon kits. It is also compatible with automated gun dispensing systems.
