Master Bond EP13LTE One component, heat curing low CTE epoxy
Categories: Polymer; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: Key Features:
  • High temperature resistance
  • Excellent adhesion to a variety of substrates
  • Passes NASA low outgassing tests
  • Withstands 1,000 hours 85°C/85% RH
Master Bond EP13LTE is a one component epoxy featuring high temperature resistance and a low coefficient of thermal expansion (CTE). This system requires heat for curing and polymerizes readily at temperatures of 300- 350°F for 1-2 hours. For optimum properties, a post cure of 2-3 hours at 350-400°F is highly recommended. It is a true one part system—not premixed and frozen, and requires simple refrigeration for storage. Foremost among its desirable properties are its high glass transition temperature (Tg) and low CTE. With post curing the Tg exceeds 160°C. EP13LTE has a paste consistency that is easy to apply and has limited flow upon curing. EP13LTE bonds well to a wide variety of substrates including metals, glass, composites, ceramics and many plastics. It is a high compressive strength system with exceptional dimensional stability. EP13LTE has good resistance to many chemicals and retains superior electrical properties, even at elevated temperatures. The color is tan. EP13LTE is especially well suited for bonding and sealing applications, where precise alignment and a low CTE are particularly important requirements.

Product Advantages:

  • Single component system; no mixing prior to use. Unlimited working life at room temperature
  • High tensile modulus and compressive strength
  • Superior dimensional stability
  • Low coefficient of thermal expansion
