 3M™ Scotchkote™ Pipe Coatings |
|
|
| |
3M has been the primary global supplier of fusion bonded
epoxy coatings for pipelines since 1960, and Scotchkote
materials have been used to coat more pipelines
worldwide than any other fusion bonded epoxy product.
Since 1960, the Scotchkote brand of products have
changed significantly with major improvements in
flexibility, adhesion, high temperature performance and
damage protection. New systems are available that
provide more choices to handle specific operating
conditions than ever before. Application standards and
overall quality of the applied coating have also increased
substantially, and 3M has been intimately involved in this
ongoing process at every step through extensive technical
service activities, involvement in industry associations,
and end user support. Take advantage of this expertise by
using Scotchkote
products on your next
pipe coating project. |

Pipeline Patch, Repair, and Rehabilitation
3M provides a complete line of patch/repair compounds for all 3M™
Scotchkote™ FBE coatings. Some are high build liquid epoxy coatings that may
also be used as field applied stand-alone coatings for general corrosion protection.
Applications include pipeline rehabilitation, pipe joints, water piping, fittings,
valves, structural members, and tanks.
Scotchkote 323/323i are ambient-temperature cure, 100% solids, two-part thermosetting
epoxy liquid coatings designed to protect metal, concrete and other surfaces from corrosion
deterioration. They may be applied in the field by cartridge, brush, roller, or plural
component spray equipment. These products are certified to ANSI/NSF Standard 61, Drinking
Water System Components.
Scotchkote 306 & Scotchkote 314 are ambient-temperature cure, two-part thermosetting 80%
solids liquid epoxy coatings designed to protect metal and other surfaces from corrosion and
deterioration. Scotchkote 306 and 314 may be applied in the field by brush, roller, or conventional or
airless spray equipment. Scotchkote 306 is color matched for repair of Scotchkote 215 and 413;
Scotchkote 314 for Scotchkote 134. These products are certified to ANSI/NSF Standard 61, Drinking
Water System Components. |

Preheating - After cleaning, parts are normally preheated to a temperature of 350OF/177°C to 488OF/253OC, then coated. |

Applying
Flocking is the
application of air
atomized powder.
Flock spray can
be used to maximum advantage when
coating parts with deep recesses and
crevices. All 3M™ Scotchkote™ FBE
coatings readily adapt to this method
of forced-air application.
The fluidized bed
consists of two
chambers separated
by a porous
membrane that diffuses air
throughout the coating powder. In
operation, the powder volume
expands and preheated objects are
coated by a dip process. Scotchkote
coatings applied by this method
encapsulate parts without sags, runs
or pinholes.
Electrostatic
coating is
accomplished
by charging
powder particles with high voltage as
they are sprayed onto an object at
ground potential. This coating
method is ideal for flat, angular, or
irregular shaped objects. Scotchkote
coatings applied electrostatically
have excellent edge coverage and
coating continuity.
Curing Curing after application is an easy process with Scotchkote. Many of the
coatings are designed for quick cure, high-speed application in
automated plants. These products are cured by residual heat imparted
during the preheat cycle and do not require a postbake. Coatings that
are applied by manually spraying and some internal coatings that
have long gel/melt cycles require postbake. Exact temperature and
time cycles may vary, depending on the objects coated and the
Scotchkote™ coating used.
Testing 3M tests Scotchkote products for properties such as
adhesion, impact strength, hardness, thermal shock,
abrasion resistance, penetration and chemical resistance.
In many cases, results are confirmed by independent
laboratory investigation. For more information on
test results please refer to the specific product data
sheet. Before use, you must evaluate the coating
to determine if it is suitable for your intended
application. |
