Fact Sheet
DusTreat* DC9136
Dust Control Binding Agent
 Provides a semi-permanent, rain-resistant crust
 Controls fugitive dust emissions from inactive
storage piles
 Protects piles against wind erosion
 Reduces inventory losses
 Reduces oxidation and coal pile fires
 Improves working conditions and community
relations
 Reduces coal pile run-off
 Effectively crusts coal, coke, metallic ores, fly
ash, waste materials, mine tailings, and various
other materials
Description and Use
DusTreat* DC9136 is blend of wetting and binding
agents specifically formulated to reduce fugitive
emissions from inactive storage piles. DusTreat
DC9136 will penetrate and bind the material to form
a cohesive, durable, rain-resistant crust. This prod-
uct does not contain sulfur or heavy metals.
The semi-permanent crust helps maintain inventory
value by suppressing dust emissions, reducing pile
rutting, and slowing the rate of oxidation by inhibit-
ing oxygen penetration. The rain resistance of the
crust will help keep the reserves available for winter
reclaim by decreasing the potential for freezing.
Typical Application
Storage piles can be a large source of fugitive emis-
sions. These emissions can be both a safety hazard
and an environmental nuisance that can grossly
affect community and personnel relations. In coal
handling systems, oxidation of the coal can signifi-
cantly reduce its heating value. Stratification of coal
piles can increase the severity of dust and oxida-
tion. In addition, pile run-off can contaminate water
resources.
The application of DusTreat DC9136 as a water so-
lution via spray systems can significantly reduce the
problems associated with open storage. Applying
DusTreat DC9136 to the surface of the storage pile
will immediately result in the binding of the fines. As
the crusting agent cures, a hard but flexible crust
will develop.
Applications of binder to protect stockpiles can be
made with conventional spray equipment. Hy-
droseeders are ideal for mixing and spraying the
binder. Trucks usually used to spray the haul roads
can be replumbed and used. The main concerns are
to reach all areas of the pile with the sprayed solu-
tions while minimizing run-off and waste of the
binder solution.
DusTreat DC9136 may be used for crusting materi-
als in rail cars or trucks. This will suppress fugitive
emissions and reduce the potential for freezing by
inhibiting water penetration. Other applications of
DusTreat DC9136 include ash piles, soil stabilization,
road berms, and pile crusting for various solid ma-
terials.
