Master Bond EP42HT-2 Epoxy Adhesive Resists Sterilization
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: Description: Master Bond Polymer System 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 or more quickly at elevated temperatures. A desirable cure schedule to optimize its properties is overnight at room temperature followed by 2-4 hours at 150-200°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 color of Part A is clear and Part B is amber. 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
  • Contains no solvents
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
