AES-450
Protective Coating
|
Storage &
Handling
|
| AES-450
is tough and flexible protective coating.
It is a 100% solids Polyamidoamine resin epoxy
especially designed for use in oilfield tanks or other
vessels where chemical resistance is required.
|
Resistance
AES-450
is highly resistant to acids, solvents, caustics,
hydrocarbons, saltwater, and freshwater.
It was developed to withstand extreme corrosive
and abrasive conditions with excellent outdoor
durability.
|
Application
Areas
AES-450
is excellent as an anti-corrosive protective lining for
floors, interior and exterior of tanks, pipe lines, boat
bottoms, swimming pools, aquariums, vats, etc.
It retains a resilient body, even after final
cure. Can be used under constant spillage, immersion
conditions, or highly abrasive applications.
It also works well as a brushing type adhesive.
|
Preparation
Surfaces
should be free of rust, mill scale, oil, paint, films,
grease, soluble salts, and other contaminants.
Sand blasting to white metal is necessary in most
cases. Concrete should be etched to provide a profile
for optimal adhesion. Latinate
and other loosely bound materials should be removed to
provide a solid bonding surface. The preparation
procedures above are general guidelines. Detailed
preparation methods are available through SSPC at www.sspc.org
or 412-281-2331 or NACE at www.nace.org
or 281-228-6200. |
Mixing
The mixing of parts A & B is
very important! Material
is supplied in two containers as a unit.
Always mix a complete unit in the proportion
supplied. Agitate
each part separately before combining the two.
AES-450 has a mixing ratio of 1½ parts “B”
to 1 part “A” (1 ½:1).
Use a jiffy mixer to thoroughly combine both
parts and mix for 2 minutes. Use Lacquer Thinner to thin
AES-450. Add no
more than one quart of solvent per gallon of epoxy.
In addition to a thinner product, it also creates
a longer pot life and easier workability. |
Application
Apply
AES-450 with a brush, 3/8” nap roller cover, or
conventional spray equipment.
Airless spray equipment should not be used.
The heat created by an airless system can shorten
pot life considerably and damage the coating and
equipment. Caution!
Without the use of aggregate, AES-450 is slippery
when wet.

Heavy
coats may be applied (up to 20 mils) without danger of
bubbling or pinholes in film.
Several coats may be necessary in building up a
heavy tank lining. Do
not apply heavier than 20 mils per coat or sagging will
occur. For heavier film, apply additional coats.
Additional
coats must be applied as soon as the surface is tack free
or within 36 hours.
|
|
Clean
Up
Application
equipment should be cleaned immediately with Lacquer
Thinner. Use
Apple Cider Vinegar to clean hands and skin. Do
not allow AES-450 to remain on tools!
Once it sets and is cured, it is extremely
difficult to remove.
