Pretreatment of the adhesion surfaces
The parts to be joined must be free from oil, grease, moisture, dirt
and release agents.
One proven method of preparing the bonding faces of plastics is
mechanical roughening of the surface (brushing, abrasive rubbing,
sandblasting). Such mechanical treatment removes adhesion-
inhibiting surface layers (e.g. release agents). Metals may either
be primed (e.g. cathodic EC, 2-component epoxy resin primer) or
they should be grinded.
The Teromix system
The Teromix system consists of the Teromix hand gun, the
efficient Teromix-6700 double cartridge and a mixer nozzle
(static mixer). Precise instructions are included with every pack.
Inserting the cartridge
Push the lock on the Teromix hand gun upwards and draw the
piston bar back as far as the stop. Place the Teromix cartridge in
the cartridge guide, unscrew the cap from the cartridge and screw
on the mixer nozzle. Cut the end of the mixer nozzle to produce
the desired size of bead.
Applying Teromix-6700
When the gun lever is operated, the material is forced through the
mixer nozzle and the two components are automatically mixed.
(Do not use the first 2 cm of extruded adhesive bead, for these
might not be perfectly mixed.) Teromix-6700 is applied directly
onto the substrate without the need for any chemical primer. Any
excess material should be removed immediately after application.
The cured adhesive within the mixer will seal the cartridge. A new
mixer nozzle will have to be used if the cartridge is re-used.
