Coherex® dust retardant provides
a clean and economical dust control. By coating the dust particles,
Coherex® creates cohesive membranes that attach themselves to
adjacent particles resulting in “agglomerates” too heavy to be
dislodged by wind. Coherex® is well suited in applications where a
controlled or regular application can be performed.
Used as a soil stabilizer in the base construction of road beds.
Added to your compaction/dust control water, Coherex® will create a
solid, dense, waterproof road base. A longer lasting road starts
with better built road base.
Coherex® is a petroleum resin and water emulsion containing no
volatiles or cutback solvents. It is composed of 60% semi-liquid
natural petroleum resins and 40 % wetting solution. The resulting
solution carries the resinous particles into the layer of dust to be
treated. The emulsion can be stored for long periods and can be
freeze stabilized for winter storage. While prolonged storage of
diluted Coherex® might result in stratification, simple agitation or
stirring will prepare the mixture for use.
Coherex® is an emulsified petroleum resin and is diluted with water
for application. Application rate depends on the area of use and
soil makeup. Typical starting dilutions of Coherex® with water are
between 1:4 to 1:7 (product : water). With a buildup of residual
over regular use, continued long-term treatments potentially can be
reduced to 1:10 to 1:15 dilutions. Application rate of diluted
Coherex® is generally ½ to 1 gallon per square yard (2-4 liters) per
square meter). The build-up of Coherex® residual also means that
areas can be graded and the build up of resin will remain in the
soil.
The “agglomeration” effect gives depth to the dust retardant and not
just a surface crust.
Apply
Coherex® by spraying the area with sufficient amount of the diluted
dust-binder to penetrate the layer of dust to the depth required.
When determining the ratio of Coherex® to water, the depth of
penetration is controlled by the total amount of product applied
(concentrate plus water) and that the thickness of the deposit of
resins on the dust particles is controlled by the amount of Coherex®
concentrate applied. The type of soil influences both the amount of
product required to saturate it and the time required to reach the
depth of penetration desired. Spreader trucks, hand sprayers,
orchard sprayers, or other standard equipment can be used. |
