Epo-Tek® ET302 Fast Setting Optical Epoxy (2.5G)

EPO-TEK® 302 is a two-component, fast-gelling, room-temperature curing epoxy, designed for electronic, optical and general applications. It is recommended as a general adhesive where convenience and speed of bonding at room temperature are desired. It can also be used for backfilling of fiber optic connectors, lens and filter mounting as well as a coating or sealant for glass, ceramics, wood, metals and most plastics.

Advantages and Suggested Application Notes:

• Due to its versatility, it may be used to adhere, seal, pot or encapsulate.
• Allows for % transmission in VIS and NIR range. It can be used as an adhesive in the optical pathway of light.
• A convenient and easy-to-use 1:1 mix ratio allows for hand, meter mix, or specialty packaging.
• Suggested Applications:
  • Field Assembly: mix and cure in the field. Fast gelling and curing in 2-3 hours is accomplished.
  • Electronics: radio prototyping of parts with fast-curing epoxy - no need for oven cycle times.
  • Optics: active alignment of optics such as lenses, prisms, diodes, filters, etc. to opto-circuit.
  • Fiber Optics: "field curing" or field assembly of connectors and couplers; also suggested for fiber optic splicing.
  • General: arts and crafts repair, restoration, and hobbyists.
