APPLICATION HINTS
We recommend using:
• Lint-free cotton cloth
• Cleaning agents [e.g. Toluene, Isopropyl al-
cohol]
Please observe the safety regulations when
using solvents. Wear gloves when working
for long periods!
In
order to ensure an optimum adhesive
bond, the surfaces of the parts to be bonded
must be dry and free from dust and grease.
In particular, traces of thermal conduction
paste or residue from mould releasing agents
on plastic housings prevent reliable bonding.
Apply HERNON 746 adhesive sparsely to
one of the bond surfaces. Apply a thin film of
HERNON EF37173 activator to the other sur-
face to be bonded.
Slightly turn the parts to be bonded and join
by pressing down firmly for several seconds
.
The ideal processing temperature is 20 …
28°C, the position of the parts can be cor-
rected within 15-30 seconds.
Wait 5 minutes for the adhesive bond to
reach approx. 70% of its final strength and
24 hours to reach 100% final strength. Ex-
cess adhesive that accumulates at the edges
can be easily removed.
Note: Never apply pressure to the rotor of a
fan! Only apply pressure to the fan frame!
