Master Bond EP46HT-2AO Black Thermally Conductive, Electrically Insulating Epoxy
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive; Epoxy Encapsulant, Unreinforced; Epoxy, High Temperature

Material Notes: Key Features:
  • Thermally conductive
  • Excellent electrical insulator
  • Long working life
  • Passes NASA low outgassing test requirements
  • Unrivaled dimensional stability
  • Exceptionally high temperature resistance
Product Description: Master Bond EP46HT 2AO Black is a two component epoxy system for demanding bonding, sealing and encapsulation applications where thermal conductivity, electrical insulation and high temperature resistance are required. It is 100% reactive and does not contain any solvents or diluents. EP46HT-2AO Black is formulated to cure rapidly and requires a cure temperature of 250°F or more. An optimal curing schedule is 3-4 hours at 250-300°F followed by a post cure of 2-3 hours at 350-400°F. The glass transition temperature is quite high, exceeding 200°C and the service temperature range is -100°F to +500°F. Once cured, EP46HT-2AO Black features exceptional physical and mechanical properties, along with exquisite dimensional stability. It bonds well to a wide variety of substrates including metals, glass, ceramics, composites, various rubbers and many plastics. It is a highly functional electrical insulator. It has very good chemical resistance to water, fuels, oils, acids and bases. Most importantly, it passes NASA low outgassing testing. The color of Part A is black and Part B is gray. This high powered combination of product properties allows this system to be used in challenging applications in aerospace, electronics, optoelectronics and in vacuum environments.

Product Advantages:

  • Extremely forgiving mix ratio
  • Very long open time at room temperature
  • Top notch heat resistance
  • Noteworthy thermal conductivity combined with fine electrical insulation values
  • High quality dimensional stability
  • Meets NASA low outgassing requirements
