EO-31FL is a flexible, electrically conductive, silver filled epoxy paste. This two-component system is designed to be cured at room temperature or the cure can be accelerated by elevated temperatures. The system is a 100% solids epoxy system, contains no solvents. This smooth, flowing paste has over 3 hours working life. This long working life enables the user to apply this material by dispensing, printing or by hand. The versatility in application methods allows its use in a wide variety of applications.

EO-31FL exhibits superior adhesion to a wide variety of substrates including most metals, ceramics, glass and plastics. This material is well suited for use in electronic component and die attach, substrate attach and EMI shielding applications. It is also widely used in low temperature and cryogenic applications.
