3M™ Scotchkote™ Product Provides Rugged Pipeline Protection That Is Easy to Apply
3M is proud to continue its legacy of pipeline protection with the launch of the 3M™ Scotchkote™
Abrasion Resistant Epoxy Coating (AREC) 328, a patent-pending new technology for the protection of
steel pipelines from the harsh effects of corrosion. An AREC combines a traditional liquid epoxy with
enhanced abrasion resistance, flexibility, and impact resistance. This allows Scotchkote AREC 328 to be
used in place of a conventional Abrasion Resistant Overcoat (ARO) or as a primary corrosion protection
coating. Best of all, Scotchkote AREC 328 is easy to apply.
The Market Need for Rugged Coatings
The Oil & Gas Industry has many options for field applied corrosion protection coatings ranging from
Field Applied Fusion Bonded Epoxies (FBE), two part liquid epoxies, heat shrink sleeves, tapes, and coal
tar enamel. More and more the popular choice has become the 2 part liquid epoxy coating. 2-part
liquid epoxies provide excellent corrosion protection and are easy to apply, but in many cases are less
rugged and less flexible than the parent coating.
Field applied Abrasion Resistant Overcoats (AROs) are also an important tool in the pipeline protection
toolbox. Every pipeline job has obstacles such as roads or rivers that may require directional drilling
and/or thrust boring. In these cases, an ARO provides extra protection to the parent coating. Factory
applied AROs based on FBE powders are good solutions, but field joints require a rugged and flexible
field applied solution. Moreover, if only a short section of pipe needs additional protection, it may
be more cost-effective to use a field applied ARO on a small section. However, many field applied ARO
solutions are difficult to apply and may lack the post-cure flexibility to provide effective corrosion
A 3M Solution for Multiple Applications
Recognizing the need for both rugged corrosion protection coatings and easy-to-apply AROs in the field,
3M has developed a 100% solids, 2-part liquid coating known as Scotchkote Abrasion Resistant Epoxy
Coating (AREC) 328.
Scotchkote AREC 328 is applied with the same ease as traditional two part epoxy coatings. This makes it
an easy way to protect factory-applied FBE coatings for directional drilling, thrust boring, river crossings,
or similar applications. Scotchkote AREC 328 is also ideal for the protection of field joints on pipe coated
with a factory applied Abrasion Resistant Overcoat such as the 3M™ Scotchkote™ Fusion Bonded Epoxy Dual
Coating System 6352.
With strong adhesion to both metal and FBE, Scotchkote AREC 328 is also effective for use as a primary
corrosion protection coating for directional drilling, rocky terrain, or other situations that require a
rugged coating. Scotchkote coating 328 also demonstrates improved flexibility (greater than 4.0 °/PD at
70°F/20°C) over traditional liquid epoxy coatings for applications which require high flexibility after cure.
With cathodic disbondment values lower than many traditional epoxy coatings, ARECs can also be used
where long-term adhesion is critical.
Scotchkote AREC 328 exhibits enhanced cathodic disbondment, adhesion, abrasion resistance, flexibility,
and impact resistance performance over traditional 2-part liquid epoxies. Learn more about Scotchkote
