Master Bond EP30HT-LO NASA Low Outgassing, Optically Clear Coating
Categories: Polymer; Adhesive; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: Description: Master Bond EP30HT-LO is a moderate viscosity, two component epoxy adhesive formulated to cure at room temperature or more rapidly at elevated temperatures, with a four to one mix ratio by weight. This is a version of EP30HT that has passed the rigorous testing for NASA low outgassing based on ASTM E595. It is 100% reactive and does not contain any solvents or other volatiles. EP30HT-LO cures rigid with dimensional stability and good physical strength properties. The shrinkage upon curing is very low—less than 0.1%. Most notably, EP30HT-LO also combines good high temperature resistance with excellent optical clarity. EP30HT-LO has good chemical resistance to oil, fuels, acids, bases, salts and solvents. Its temperature range is from -60°F to +400°F. EP30HT-L O has excellent adhesion to a variety of materials including metals, glass, ceramics and many rubbers and plastics. It is a good electrical insulator and can be readily used for smaller encapsulation applications. To optimize the properties for outgassing applications, it is recommended to post cure this system for 2 hours at 150-200°F. It is widely used in the aerospace, electronic, vacuum, optical, fiber-optic and OEM industries.

Product Advantages:

  • Convenient handling and easy to apply.
  • High mechanical strength, excellent structural adhesive.
  • Good optical clarity, high light transmission properties.
  • Outstanding electrical insulation properties.
  • Good chemical and temperature resistance.
  • Forms dimensionally stable, rigid bonds.
  • Meets NASA low outgassing requirements.
