Specifications
Master Bond EP21AOLV-2Med has biocompatibility and cytotoxicity certifications, and it is often chosen for sealing, bonding, coating and encapsulation applications in the industry of medical devices. This two-component epoxy system endures a range of sterilization methods, such as EtO, radiation and many cold sterilants.
EP21AOLV-2Med is thermally conductive and electrically isolating with good flow properties and seamless consistency. It bonds well to metals, glass, ceramics, composites, plastics and several rubber materials.
This dimensional system provides a high-tensile modulus of 500,000–550,000 psi — a compressive strength surpassing 22,000 psi — and very low shrinkage when cured. EP21AOLV-2Med’s viscosity and low coefficient of thermal expansion make it ideal for encapsulation and potting applications.
Also, it resists several chemicals such as fuels, oils and water. This medical-grade product is serviceable over the temperature range of –60 °F to +250 °F.
Featuring a one-to-one mix ratio by weight, a 100 g batch of EP21AOLV-2Med has a working life of 4 to 6 hours at room temperature. Part A is gray and Part B is off-white, which also eases mixing. It can be easily applied with a spatula, trowel, knife, brush or paint roller.
This system cures at room temperature or more quickly when heat is added. EP21AOLV-2Med has a shelf life of nearly six months in its original, unopened containers and comes in half-pint kits, quart kits, pint kits, gallon kits and five-gallon kits.
