Epoxy Technology EPO-TEK® 302 Fast Setting, Optical Epoxy
Categories: Polymer; Thermoset; Epoxy

Material Notes: Product Description: EPO-TEK® 302 is a two component, fast-gelling, room temperature curing epoxy, designed for electronic, optical, medical, and general applications.

Advantages & 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.
  • 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: rapid 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.
  • Medical: adhesion to most metals, plastics, ceramics, and glasses found in tubing, substrates or housing.
  • General: arts and crafts repair, restoration, and hobbyists.
