GT 12097 epoxy silver conductive glues

Use : GT 12097 is two-component silver-loaded epoxy, specially designed as a chip adhesive for when low temperature
polymerisation is required. GT12097 is also recommended for applications needing high temperature polymerisation
: at 105°C, GT12097 polymerises in 5 minutes, unlike the 30 minutes needed by many single component products .
This low viscosity resin contains no solvents

Life span : Before mixing, the resin has a life span of 2 years in ambiant conditions; mixed product remains usable
foR 4 days also at ambiant. Due to its long mixed lifespan and the absence of solvents, GT12097 is ideal for us on
automated production lines. The combination of a long lifespan when mixed and rapid polymerisation mean that
GT 12097 is an ideal production optimistion tool.

Temperature : Experience demonstrates that, polymerised above 120°C, GT12097 withstands soldering
temperatures of 300°C to 400°C.
