RepliSet
The RepliSet system is designed to
produce an exact 3D copy of a surface.
It is used for non-destructive testing and
field applications allowing the structure
or irregularities on critical components to
be examined and measured under labo-
ratory conditions.
RepliSet is a specially formulated fast
curing two-part silicone rubber with a
good releasing ability for flexible high-
resolution 3D replicas, which behave like
a metallic surface when examined in an
optical microscope.
RepliSet compounds are supplied in car-
tridges and are dispensed using a hand-
operated dispensing gun. The cartridges
contain both polymer and curing agent,
which are automatically mixed in a dis-
posable static-mixing nozzle during ap-
plication to the surface. The application
system offers superior and fast results,
regardless of the conditions.
RepliFix is a less advanced parallel
to RepliSet. RepliFix and RepliSet are
designed to bond together. The two com-
ponents are mixed and applied by hand.
RepliFix is used as support for RepliSet
or as a stand alone product for moulding
of surface shape for low tech applica-
tions.
A backing slide bonds to the RepliSet or
RepliFix replica. The backing slide serves
to maintain the original profile and en-
sures a flat back to the replica.
A replica can be taken from all metallic
materials and most other solid materials
like ceramics, plastics and glass. There
are no size, shape or thickness limita-
tions on the replicas that can be made
and it is even possible to take replicas
from othervise inaccessible surfaces.
The RepliSet system can produce repli-
cas, which at the same time are dimen-
sionally correct, with ultra fine detail
reproduction and with a flat back.

Magnification 100 x
Further to examination by optical micro-
scopes, 3D examination can be carried
out using non-contact measuring instru-
ments such as laser measuring equip-
ment or measuring projectors with 2D
or 3D facilities. A replica of a cavity, for
instance inner holes, can be examined
using measurement and profile projec-
tors. The replicas are suitable for 3D
examination by SEM.
Metallographic applications
Typical applications are on-site non-de-
structive testing in connection with qual-
ity control, inspection and maintenance
of power plants, oil platforms, bridges,
aircraft, etc.
Water or high temperatures do not affect
RepliSet so the application range is very
broad.
Sample Replica
Typical tasks are:
- Quality control of edges, corners,
heights, angles, surface finish and
other dimensions.
- Inspection of internal surfaces such
as bolt hole threads.
- Detection and monitoring of pitting,
corrosion, cracking, creep and wear.
- Metrology.
- Forensic investigation.

An operator dispenses
RepliSet onto a sample,
and then peels off the
