Master Bond EP35 Two component, room temperature curing epoxy for bonding, sealing and coating
Categories: Polymer; Thermoset; Epoxy; Epoxy Adhesive

Material Notes: Key Features:
  • Good flow properties
  • Excellent machinability
  • High temperature resistance
  • Withstands 1,000 hours 85°C/85% RH
Master Bond EP35 is a two part, room temperature curing epoxy system used for bonding, sealing and coating featuring high temperature resistance. It has superior dimensional stability and is easier to machine compared to other epoxies. It has a 100 to 70 mix ratio by weight and a very convenient one to one ratio by volume. This system cures readily at room temperature or more rapidly at elevated temperatures. To optimize its properties, the recommended cure schedule is overnight at room temperature followed by a post cure at 150-200°F for 2-3 hours. Once cured EP35 has an exceptionally high temperature resistance, serviceable up to +450°F. It resists a range of chemicals including water, oils, fuels and many acids and bases. This system bonds well to a large variety of substrates including metal, glass, ceramics and many rubbers and plastics. It is a reliable electrical insulator. EP35 is 100% reactive and does not contain any diluents or solvents. The color of Part A is gray, Part B is amber. It is widely used in aerospace, electronic, electrical and specialty OEM type applications.

Product Advantages:

  • Convenient mixing: one to one ratio by volume
  • High temperature resistance up to +450°F
  • Excellent dimensional stability
  • Easily machinable
