RODREPEL ® - Non-hazardous Bird
and Animal repellant
This unique and novel product is offered as a Non Hazardous and
Non Toxic bird and animal repellent. It is based on a quaternary
ammonium adduct of a purine based synthetic Animal repellent perfume
and oleoresin derivatives.
Rodrepel Masterbatches ® are also available. These
are universal masterbatches, recommended addition level of this
masterbatch is 1%-5%.This masterbatch is based on LDPE or EVA. Specially
formulated masterbatches are also available on request.

EFFECTIVENESS
On laboratory tests conducted with Cables containing RODREPEL®,
it was demonstrated that cables that were bitten by rats produced
a very foul reaction in the animal, without harming it in any way.
In 100% of cases, the animal did not bite into the cable again.
These tests are carried out across a period of time. RODREPEL®
actually helps in modifying animal behaviour.
Testing is done on actual cable or pipe pieces simulating actual
conditions as that would exist in the environment.
RODREPEL® is effective at very low concentrations e.g.
200ppm (parts per million). However the dispersion of Rodrepel®
in polymers requires dosages from 200-2000 ppm depending on the
dispersion process and application.
In polymeric application we suggest the use of Rodrepel® Masterbatch,
this masterbatch has been produced using a patented process developed
by C Tech Corporation, the Rodrepel® Masterbatch is designed
for optimum dispersion and ease of handling.
COMPATIBILITY
RODREPEL® is 100% organic in nature and is non-hygroscopic.
It is compatible with all thermoplastic and thermosetting polymers
such as PE, XLPE, PP, PVC, polyesters, epoxies and paints, both
water and oil based.
APPLICATIONS
- Cable protection from rodent damage
- Plastics requiring protection from animal and bird damage
- Variants of RODREPEL ® can be added to Pharmaceutical
preparations or other poisonous substances to prevent accidental
ingestion by children
- Can be added to Pesticides to avoid accidental ingestion
- Can be used to prevent cribbing in animals
- Suitable for topical applications to prevent e.g. thumb sucking
SAFETY and HANDLING
The product is non-toxic to humans.
Special precautions in handling are the use of face masks and gloves
to prevent accidental ingestion.

Addition & compounding in Polymers:
C-Tech Corporation's chemists started studying animal behaviour
& also realized why animals are drawn to plastics products,
the plasticizers & the aromatic odours of polymers, the bright
colours & the texture of polymer products are all responsible
for animals being attracted to plastic goods.
Rodents are present everywhere & can cause a lot of damage
to power cables. They chew on plastic doors, sidings, benches moulded
plastic parts, cables, wires, railway components, practically anything.
In the wild too, several animals chew on products made of plastics
such as plastic bins containers, cables etc.
Rodents chewing cables, exposing them & causing a short circuit
also cause a few fires.
The best part about the RODREPEL® family of products
was that these products were not dangerous to both humans &
animals.
We also started manufacturing special perfumes mimicking the smell
of predator urine & incorporated these perfumes into RODREPEL®,
the non-toxic bird & animal repellent product we produced for
polymers. These perfumes are not detected by the human olfactory
sense, but animals read this as a signal for danger. RODREPEL®
also contains oleoresin derivatives, these are extracted from green
peppers, these peppers are found very commonly in India & are
extremely spicy, and they are often used in the extremely spicy
Indian curries.
RODREPEL® is effective at parts per million levels, thus it
does not interfere with the physical or chemical properties of polymers
or compounded polymers. Similarly we developed these products to
withstand the extreme heat of polymer processing, extremely small
particle size to help in the dispersion of these products in all
kinds of plastics. The suggested loading in polymers is 500 parts
per million or 0.05%, at such small loadings the physical properties
of the polymers or the compounding process are not at all affected.
We have got terrific results with RODREPEL ®.

on RODREPEL ®
RODREPEL® has been incorporated as an
aerosol spray, used as gel to protect from woodpeckers & other
birds, used on roofs.
RODREPEL® has been very successfully added to Wires & Cables,
Plastic screens & sidings, railway doors & windows, seats,
wires & cables used in automobiles.
The graphs below will explain the effective use of RODREPEL ®
& the results we obtained.
RODREPEL® used in PVC Cables & Wires

It is possible to modify the behaviour of animals. We have seen
quite conclusively in the laboratory or the wild, that the number
of animal attacks on plastic objects decrease gradually with time.
Subsequent generations of animals also stay away from polymer objects,
to which RODREPEL® has been added. RODREPEL® thus
works by modifying animal behaviour instead of poisoning the animals
in any way. RODREPEL® works at very small concentrations
without modification of the inherent property of the polymer or the
compounded polymer finished products. RODREPEL® can be used
in any polymer system as it is used at 0.05% active concentrations.
We have tried RODREPEL® in most polymers with excellent
results.
WHY RODREPEL ®
Rodent damage to cables & optical fibre conduits often disrupts
power supply and is a cause for many fires due to short circuits
& also causes service outages.
RODREPEL® is an unique Non toxic Rodent repellent for
wires & cables. RODREPEL® is also available as a master
batch.
HOW DOES RODREPEL® work?
RODREPEL® works on the following 5 principles,
- Aversion, By adding an extremely foul tasting component to
the Cable sheath.
- Discomfort, By adding a component which causes severe distress
to the mucosa of the animal
- Fear, by exploiting the olfactory response of animals to compounds
which mimic the behaviour of predator urine
- Training, the animal learns that Rodrepel® is not a nice
thing to bite into. By Modification of Animal Behaviour towards
products made from Rodrepel®, this involves sensory stimuli
modification
- Association and conditioning, the animal would remember the
bad experience, it is also found the animal passes on the information
to its progeny. The fear response & unpleasant reaction is
also communicated to other animals in the vicinity.
SAFETY ASPECTS & ENVIRONMENT
RODREPEL ® is actually designed not to harm the rodent
or animal in any way. We are committed to our environment &
we believe that no harm must be caused to animals or to the environment.
RODREPEL® does not leach out to pollute. It is completely
inert
Cables & pipes often pass through large expanses of untouched
forests & outdoors, several native & protected species often
come into contact with these cables. Thus RODREPEL ® is
designed to be a completely harmless product.
In fact, it is the world's one & only complete Non Toxic Animal
repellent for Polymers.
POLYMER PROCESSING
Due to the small amount of addition levels suggested, RODREPEL®
does not interfere with the physical or mechanical properties of
the polymer. RODREPEL® is completely inert in nature.
RODREPEL® works by repelling the animals & by conditioning
the response of animals, without harming the animals in any way.
Rodrepel® is also available as a pre-dispersed formulated masterbatch
which offers excellent dispersion.
