| A long term field test monitored by the Swedish
Corrosion Institute has resulted in remarkable findings for
functionalised polyolefin alloys such as PPA 571.
After 11 years of being buried in the salty clay soils around
Gothenburg six water pipes coated with thermoplastic polyolefin alloys
were dug up for examination and were found to be in outstanding
condition.
The pipes showed absolutely no rusting, cracking or flaking. In fact
all of the test pieces were deliberately damaged before they were laid
and the spread of these defects such as scratching, holes and blow marks
were also found to be nil.
The Swedish Corrosion Institute has indicated that water pipes in
similar conditions, coated with Plascoat PPA 571 would have a
lifetime of over 200 years.
PPA 571 has been used for water pipes all over the world from snow
making in Switzerland to the seaport in the US city of
Seattle. It has a
wide range of
water approvals including NSF61 and
conforms to the requirements of FDA food contact.
PPA 571 is available for both fluidised bed and electrostatic
spraying.
