Vibra-TITE 321 is a single component low viscosity
cyanoacrylate adhesive. It is specially designed for
silkscreen applications in the graphics industry.

Curing Properties
Ambient surface moisture will initiate the hardening
process. Handling strength is reached in a short period
of time and varies depending on environmental
conditions and substrates being bonded. Product will
continue to cure for at least 24 hours before full strength
and resistances are developed.

Curing Performance
The gap of the bond line will affect set speed. Smaller
gaps tend to increase the speed. Activators can be
applied to improve set speed but may also impair overall
adhesive performance.

General Instructions
Surfaces to be bonded should be clean and dry.
Dispense a drop or drops to one surface only. Apply only
enough to leave a thin film layer after compression.
Press parts together and hold firmly for a few seconds.
Good contact is essential. An adequate bond develops in
less that one minute and maximum strength is attained in 24
hours.
Wipe off excess adhesive from the top of the container and
recap. Cyanoacrylate products if left uncapped may
deteriorate by contamination from moisture in the air.
Because Cyanoacrylate products cure by polymerization,
whitening may appear on the surface of the container or the
bonded materials. Should this happen, wipe surfaces well
with acetone.
