PennzSuppress® D-Dust Suppressant
Certified Performance Claim
The certification of PennzSuppress® D is based on its use as a dust suppressant in accordance with the manufacturer’s instructions. PennzSuppress® D, when topically applied as a dust suppressant (0.15 gallons of concentrate per square yard of treated surface), reduces PM10 emissions by approximately 85 percent after 7,000 vehicle (predominantly light-duty) passes on an engineered unpaved road consisting of a well-graded aggregate.
PennzSuppress® D is a patented product designed to control dust, stabilize soil and control silt run-off from unpaved roads. PennzSuppress® D is composed primarily of a petroleum resin that contains C-25 and higher hydrocarbons. The product relies upon its high carbon-index resin to agglomerate a road’s soil particles and increase the cohesion among the aggregate particles. The agglomeration potential and the increase in cohesion hold the aggregate, including the dust particles, in place.
The PennzSuppress® D is used as a dust suppressant on engineered unpaved roads consisting of well-graded aggregate. Engineered unpaved road means a purpose-built road. Well-graded aggregate is an engineering term that defines road material with a wide range in grain sizes.
