Cationic Emulsion Notice
Certain Cationic Emulsions are known to be corrosive to carbon steel, aluminum, and even some
grades of stainless steel. Hydrocloric acid is often used in cationic emulsions to produce the electronic
charge that makes the emulsion cationic. Cationic emulsions may be identified by the “C” at the beginning
of the product name or identification number, such as “CRS-2” or “CSS-1”. Cationic emulsions with low
amounts of residual asphalt, (below 60%) such as “CSS-1” have been found to cause corrosion to a
greater extent than those containing a higher percentage of asphalt.
Tanks used in cationic emulsion service may experience unexpected corrosion inside the tank,piping
and spray bar system. This corrosion may be worse if the tank is left loaded with a cationic emulsion
containing a low asphalt content, over extended periods of time, or in continuos use.The effects of this
corrosion activity may be lessend by alternating cationic emulsions with other products in the tank, such
as anionic emulsions, cut backs, or asphalt cements. Take necessary precautions whenever changing
types of asphalt to avoid boiling the water from emulsions when loading “HOT” asphalt cement.
Periodic inspection of tank should be performed in the normal course of operation. It becomes even
more important in the case of cationic emulsions. Visual inspection of the inside of the tank should be
performed regularly. Removal of the spray bar end caps will allow visual inspection of the spray bar. If any
corrosion is noted, the tank, piping, and spray bar should be flushed with a cut back asphalt, such as an
“MC” grade or with an asphalt cement.
Warning
Fluoroelastomer Handling
Some O-rings and seals used in this vehicle are made from fluoroelastomers, When used under design
conditions, fluoroelastomers do not require special handling. However, when fluoroelastomers are heated
to temperatures beyond their design temperature (around 600º Fahrenheit), decomposition may occur
with the formation of hydrofluoric acid. Hydrofluoric acid can be extremely corrosive to human tissue if not
handled properly.
A degraded seal may appear as a charred or black sticky mass, Do not touch either the seal or the
surrounding equipment without wearing neoprene or PVC gloves if degradation is suspected. Wash parts
and equipment with 10% lime water (calcium hydroxide solution) to neutralize any hydrofluoric acid.
If contact with the skin occurs, wash the affected areas immediately with water. Then rub a 2.5 calcium
gluconate gel into the skin until there is no further irritation, while seeking prompt medical attention.
Note to Physicians: For advice or treatment of HF burns, call the DuPont Medical Emergency number,

WARNING
To prevent possible burns from hot asphalt
spray: Do not stand, or allow anyone to
stand, where accidental opening of a valve
may cause contact with hot asphalt.
Spray bar nozzles have a limited flow range at
which optimal performance will be achieved. Flow
rates greater than this optimal range will cause
excessive fogging. Rates that are too low will
cause the fan to sag and cause heavy edges.
Refer to the nozzle selection chart in the
operator’s manual to select the nozzles appropri-
ate for your conditions.
Adjusting the Spray Bar Nozzle Angle
Adjust the nozzles to obtain an angle of
approximately 30 degrees with the spraybar
centerline. Every nozzle should be at the same
angle. A nozzle adjustment wrench is supplied
with each new unit.
