ERA-168 EPOXY ADHESIVE WITH VARIABLE FLEXIBILITY




ERA-168
EPOXY ADHESIVE WITH VARIABLE FLEXIBILITY


ERA-168 is a controlled flexibility epoxy adhesive. It is designed for use where shock and peel resistance
is desired. It can be cured at room temperature or more rapidly at an elevated temperature. Adhesion to
metal, glass, ceramic and plastic is excellent. The flexibility of the adhesive is determined by the amount
of hardener used. Apply the material using a brush, knife or roller.

INSTRUCTIONS FOR USE:

Mix ERA-168A before each use. Weigh out the desired amount of epoxy and then add the correct amount
of ERA-168B depending on the required flexibility. Mix thoroughly and degas if necessary. The pot life is
at least 3 hours at room temperature (25
o
C). The adhesive will set up after 8 hours at 25
o
C but it will
require 24 hours to reach maximum bond strength. The material may be cured more rapidly by following
the alternate cure schedule.
