Master Bond Supreme 12AOHT-LO One Component Epoxy
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive; Epoxy, High Temperature

Material Notes: Key Features:
  • Cryogenically serviceable
  • Superior ability to withstand thermal cycling
  • Convenient handling, no mixing and no freezing
  • Excellent bonding and physical strength properties
  • High temperature resistant
  • Exceptionally low shrinkage upon curing
Product Description: Master Bond Supreme 12AOHT-LO has an impressive combination of easy and straightforward processing along with an array of superb properties after curing. It is a single component system that cures at 125°C (257°F) in 60-70 minutes and 150°C (302°F) in 40-50 minutes. There is no need for it to be stored frozen. Additionally, it has unlimited working life at room temperature. Upon cross-linking, Supreme 12AOHT-LO has numerous favorable attributes highlighted by excellent thermal conductivity, superior electrical insulation and the ability to withstand rigorous thermal cycling. It bonds well to a wide variety of substrates, including metals, composites, glass, ceramics and many plastics. This epoxy has formidable bond strength, particularly in the shear mode, exceeding 3,500 psi. The service temperature range is eye-catching, extending from 4K to +500°F. Also, it truly qualifies as a NASA low outgassing system. Along with the attractive profile, this structure has superlative dimensional stability and a robust aggregation of physical strength properties. Supreme 12AOHT-LO is a toughened system with superior resistance to aggressive thermal cycling and shock. It is notable for its dimensional stability and its impressive array of physical strength properties. Supreme 12AOHT-LO has ample chemical resistance, particularly to water, oil, fuels and solvents. It is gray in color. Supreme 12AOHTLO is a compelling choice for bonding and sealing in aerospace, electronic, electro-optic, specialty OEM as well as for vacuum environments, where the combination of convenient processing and handling along with the extensive performance profile discussed previously is highly desirable.

Product Advantages:

  • Single component system; no mixing prior to use
  • Unlimited working life at room temperature
  • High bond strength, particularly lap shear
  • Extraordinary temperature range from 4K to +500°F
  • Fully meets ASTM E595 for low outgassing
  • Capable of withstanding rigorous thermal cycling
  • Combines excellent electrical insulating values along with substantial thermal conductivity
