Product Description

Master Bond EP21LVMed is a two component, low viscosity epoxy resin system for high performance bonding, sealing, coating, encapsulating and casting. It is formulated to cure readily at room temperature or more quickly at elevated temperatures. To optimize the system’s properties and to ensure biocompatibility, a highly recommended cure schedule is overnight at room temperature followed by 2-3 hours at 150-200°F. It has a convenient one to one mix ratio by weight. EP21LVMed produces high strength, durable bonds which hold up well to thermal cycling and resist many chemicals including water, acids, bases and most importantly, EtO, radiation and many cold sterilants. It is serviceable over the wide temperature range of -65°F to +250°F. It bonds well to a variety of substrates including metals, glass, ceramics, wood, rubbers and many plastics. Once cured, EP21LVMed is an outstanding electrical insulator. This, combined with its low viscosity, makes this system an excellent encapsulating and potting epoxy. It fully passes USP Class VI testing for biocompatibility and it is widely used for medical applications. EP21LVMed contains no solvents or diluents. The color of Part A is clear, while the color of Part B is amber.

Case Studies

In a thesis titled "An Implantable Device for Electrical Nerve Stimulation" from the Norwegian University of Science and Technology, Lars Lye Moen designed a prototype for an implantable electrical nerve stimulator with the ability to be miniaturized into 1/4 of the size of similar stimulating systems. This was designed primarily for use in VNS applications (Vagus Nerve Stimulation).
