- Model LM (AC-900) Series - Long Duration Foam



RusFoam LM long duration foam products (LM4, LM12 and LM20) produce an impermeable, flexible membrane that seals a surface to prevent release of emissions. RusFoam LM utilizes foam as a distribution method for latex. After the foam has been applied, the air bubbles begin to collapse and the latex cures to form a continuous flexible membrane that adheres to the substrate for long term control of dust, odors and volatile organic compounds (VOCs). RusFoam LM is designed for use with all Rusmar Pneumatic Foam Units. RusFoam LM is available in black, red, brown, yellow and green. Wintergreen or vanilla scents can be added.

RusFoam LM is recognized by the U.S. Environmental Protection Agency, the U.S. Army Corps of Engineers, state agencies and major corporations as providing superior emission control for periods up to 6 months. RusFoam® LM has been specified for use at Superfund and other hazardous waste sites across the United States and Canada, as well as elsewhere in the world.

The primary application for RusFoam LD is control of odors, VOCs and dust for extended coverage of contaminated soils at hazardous waste sites. RusFoam LM can also be applied on liquid surfaces, such as lagoons and retention ponds. Depending on the formulation selected, RusFoam LM will provide effective coverage for up to 6 months.

Controls Challenging Odor Problems
The remediation of hazardous waste sites often includes excavation of soil contaminated with odorous compounds that are stockpiled for later removal or treatment. RusFoam LM forms a barrier between the substrate and the atmosphere and provides an effective method for containing odors and emissions emanating from these stockpiles for extended periods. RusFoam LM can be applied on liquid surfaces, such as lagoons and retention ponds for extended odor and emission control. It is completely biodegradable and poses no threat to workers, neighboring residents or ground water.

RusFoam LM can also be applied on top of trucks, railcars and barges for emission control during transport of materials such as contaminated soils or sewage sludge.

Controls Fugitive Dust
At hazardous waste sites, fugitive dust can present a health hazard. RusFoam LM can be applied to the dusty material to prevent any wind-borne emissions. The initial foam application provides immediate control and the latex membrane provides coverage for extended periods.

Controls Fugitive Dust
Graded areas can be covered with RusFoam LM to reduce erosion damage caused by rain, melting snow or ice and wind. Sand and other high percolation soils do not effectively repel water. Covering such substrates with RusFoam LM will dramatically reduce soil permeability.

Controls Fugitive Dust
RusFoam LM is supplied in either 450 pound (200L) drums or in bulk. Bulk shipments can be stored outside in a Rusmar Bulk Storage-Dilution System. The Bulk Storage and Dilution system is comprised of a 7000 gallon (26.500L1 heated and stirred chemical storage tank with a microprocessor to accurately dilute and transfer the chemical. RusFoam LM is designed to be applied with all Rusmar Pneumatic Foam Units.
