III. Directions for
use:
Surface preparation:
1. Metals
The bonding surfaces must be free of dirt,
rust, oil and grease, oxidation and
eloxated layers.
Clean surfaces with acetone or white
spirit and roughen them with abrasive
paper.
Leave on well-fixed coatings if the
required bonding strength is not very
high.
2. Plastics
Carefully remove oil and grease with
adequate solvent, e.g. white spirit or
alcohol. For rigid-PVC, ABS,
polystyrene and SAN roughening of
surfaces is not necessary.
Roughening of acrylic glass and
celluloseacetobutyrate increases
bonding strength. To remove
separating agents roughening is
absolutely necessary with glass-fiber
reinforced plastics.
3. Glass, ceramics, porcelain, marble,
stone
Clean surfaces with acetone, ethanol,
white spirit or clean with scouring agent,
rinse with water and allow to dry. Glass
or ceramics surfaces (e.g. tiles) can be left
smooth, roughening of surfaces will
considerably increase bonding strength.
4. Concrete
Concrete has to set completely
(> 28 days) and dry.
Clean surface from separating agents with
soap water. Remove dirt using a wire
b
rush. To remove ingrained paint use
ammonium chloride or sand paper.
5. Wood
Clean surfaces from dust and other
separating agents. Sand down varnish
coatings. Remove oil and grease with
solvent.
6. Further
With most materials, cracks will not need
any special preparation as long as the
surfaces are dry and free of grease.
Adhesive mixing:
The working set of 30 g consists of one
ready-for-use mixing trough, the
80 g set contains three ready-for-use
mixing troughs. Depending on amount of
Pattex Stabilit Express needed, put one,
two or three spoons of hardener powder
into the mixing trough. Then fill up the
mixing trough completely with resin and
thoroughly mix together the two
components with the spatula.
Adhesive application:
Application time:
Apply within 10 min. after the two
components have been mixed.
Application time extends at lower
temperatures.
Apply Pattex Stabilit Express with plastic
spatula onto both surfaces to be bonded.
If both surfaces are smooth only apply on
one.
Then join the two surfaces applying
moderate pressure and fix until initial
b
onding strength is reached (approx. 20
min.)
If the bonding are under high stress it is
recommended to fix until final strength is
attained (1 hr.). Remove any adhesive
remnants immediately, use acetone if
necessary.
Note that adjusting is only possible during
the application time of 10 minutes.
IV. Important
remarks:
Tools cleaning:
To remove adhesive remnants from
the mixing trough press its bottom
part.
Dissolving of bonding:
Hardened adhesive has very high
bonding strength. To dissolve
bonding, heat up the surfaces to
150°C. Or put the bonded surfaces into a
solvent containing bath, allow solvent to
react.
Precautionary measure:
Both components are combustible if not
hardened. Keep away from sources of
ignition. Do not smoke during adhesive
application. Use only in well ventilated
areas! (At high concentration and long
influence monomers from resin could
cause irritation). Harmless when cured.
Storage:
Store in a cold, dry place. Freezing is
possible (heightens shelf life). Avoid
temperatures above +30°C.
Shelf life:
Approx. 12 months at 20°C.
Warning:
F = highly inflammable
Xi = irritant.
Keep out of the reach of children.
The above instructions are based on thorough trials and on general experience gained in this field. As it is impossible to survey all installation
methods and in view of various different working conditions, we cannot, however, claim that the information given is complete. We therefore
recommend that tests should be carried out on your own to ensure the greatest possible success. We guarantee a uniform quality standard for this
