Researchers at US laboratories and universities collaborated to demonstrate how a microfluidic valve-based pressure injector used with capillary-based CE–MS analyses will enable the high-throughput analysis of large numbers of samples for, e.g., measurement of prefractionated samples from an orthogonal separation. In this study, they cited Master Bond as follows: "Fused-silica capillaries were from Polymicro Technologies (Phoenix, AZ), and acid enduring epoxy (EP42HT-2) was from Master Bond (Hackensack, NJ).”1
Two component, room temperature curing epoxy compound
Key Features
- Heat, chemical and steam resistance
- Cures at ambient or elevated temperatures
- Can be used for bonding, sealing, coating, casting & potting applications
- Serviceable from -60°F to +450°F
Product Description
Master Bond EP42HT-2 is a room temperature curable, two component epoxy adhesive, sealant, coating and casting material featuring high temperature resistance along with outstanding chemical resistance. While EP42HT-2 is a superior adhesive, sealant and coating, it is also relatively low in exotherm and castable up to 2-3 inches thick. EP42HT-2 cures readily at ambient temperatures in 2-3 days, or in 2-3 hours at 200°F. The optimum cure is either of these schedules followed by an additional post cure for 3-5 hours at 225-300°F. EP42HT-2 has an easy to use 100 to 40 mix ratio by weight or 100 to 50 by volume. It is resistant to a wide variety of acids, bases, solvents, fuels, oils and salts. It also has excellent electrical insulation properties. Its service temperature range is from -60°F to +450°F. EP42HT-2 is used in electronic, electrical, fiber-optic, optical and OEM type applications. The regular color of Part A is clear and Part B is amber. It is also available in black and other colors, upon request. The system has superior optical transmission properties, particularly in thinner sections, as well as a high index of refraction for an epoxy.
Product Advantages
- Non-critical 100 to 40 mix ratio by weight or 100 to 50 by volume
- Easy application: only contact pressure required while curing; adhesive spreads readily
- Excellent chemical resistance to acids, alkalis and many solvents
- Castable up to thicknesses of 2-3 inches
- Outstanding physical strength properties
- Superior optical transmission properties
