Master Bond EP40Med, a two-part epoxy system, has received the International Organization for Standardization (ISO) 10993-5 certification for meeting the requirements of ISO 10993-5 testing and is now considered to be non-cytotoxic. The compound can be used for bonding, sealing, coating and encapsulating.
Low Tensile Modulus with High Lap Shear Strength
Master Bond EP40Med combines toughness and a low tensile modulus while still providing a relatively high lap shear strength. The epoxy system resists sterilization to gamma, EtO, chemicals, and liquid disinfectants. It is recommended for the use in medical device manufacturing and repair for both disposable and reusable instruments.
Master Bond EP40Med is an effective adhesive for applications where toughness and flexibility along with good structural strength are needed. The formulation bonds well to polycarbonates, acrylics, metals, ceramics and composites. The flexible epoxy has an elongation of 80-90 percent, a lap shear strength of 1,600 to 1,800 psi and a low tensile modulus of 25,000 to 50,000 psi. Master Bond EP40Med is a reliable electrical insulator with a volume resistivity of over 1012 ohm-cm.
Working Life and Availability of Master Bond EP40Med
The epoxy system is easy to use with a one-to-one mix ratio by weight or volume and a low to moderate viscosity of both parts A and B. The working life of a mixed 100 g batch is approximately 120-150 minutes. The optimal cure schedule is overnight at room temperature followed by a post-cure for 2-3 hours at 150°F. The product is available in half pint, pint, quart, and gallon kits. Specialty packaging is available in gun dispensers and premixed and frozen syringes.
