  • Very long open time
  • Good flow properties
  • Withstands 1,000 hours 85°C/85% RH

Product Description

Master Bond EP34CA is a two component epoxy system specially formulated to resist higher temperatures and aggressive chemicals. This lower viscosity material has an easy to use 100 to 50 mix ratio by weight. It will not cure at room temperature and it has an exceptionally long working life, far exceeding 24 hours. Although, it is slightly exothermic, it can be cured in sections exceeding 1/4 inch thick. Particular attention should be paid to the curing schedule. The main attribute of EP34CA is as a high temperature resistant structural type adhesive, although it has many other outstanding properties as well. In this context, it can be used for filament winding, tooling compounds along with bonding composites and pultruded structures. As mentioned previously, it bonds well to a wide variety of substrates, including metals, composites, glass and many plastics. EP34CA is highly resistant to water, oils, acids, bases and solvents. It has top notch physical strength properties and is a superior electrical insulator. The color of Part A is black, and Part B is amber. The service temperature range for this system is -80°F to +500°F. EP34CA is specified in many applications in aerospace, electronics, optical and specialty OEM, where the special combination of properties described above is needed.
