3C21 Choosing the right coating
There are many different
coatings to choose from when
it comes to coating metal
tubular items. The buyer can
choose liquid paints, tape-
wrap, sacrificial coatings, epoxy
coatings or powder coatings.
The powder coating market
comprises thermoset and
thermoplastic powders, with the former
product group often referred to as simply
powder coatings. Thermoplastic coating
powders melt onto the metal under the
influence of heat and then solidify into
a coating. No reaction takes place and
they contain no reactive ingredients.
Choosing the most appropriate coating
is dependent on the environment the
products will be exposed to. If they will
be exposed to water, acids in soil, UV
light, impacts, abrasion, chemical attack,
physical flexing, temperature extremes
or graffiti, polyolefin (thermoplastic)
coatings can be considered.
Thermoplastics are flexible yet tough.
They generally cannot chip or crack,
and adhere to the metal well. Polyolefin
thermoplastics in particular adhere very
well to metal without the need for a
primer. They contain no plasticisers,
BPA or TGIC and nothing can leach into
the environment or soil.
Polyolefin coatings are typically
supplied in powder form and can be
easily applied to tubular products
by electrostatic spray, flock spray or
fluidised bed dipping methods.
They are of benefit to manufacturers or
coaters because primers and chemical
curing are not required; they will not
chip, crack or flake; and no hazardous
fumes are generated on application.
The end customer has the reassurance
that coated assets will last for decades
with little to no maintenance costs,
and with no future environmental
liability. They are resistant to UV, wind
blown sand abrasion and sub zero
temperatures, and can withstand the
rigours of urban life such as graffiti.
Plascoat states that its polyolefin coating
powders are becoming increasingly
specified in the oil and gas, water and
street furniture markets, and are already
widely used to coat tubular products in
Europe, Asia, Australia, and South and
North America.
