Ellis Paint Company http://www.ellispaint.com/

Capture Permacoat

Latex flexible impermeable barrier. Sprayed, rolled or brushed for permanent contamination encapsulation

Originally formulated for ocean-going cargo containers. Very durable and very resistant to the elements

Midwest Industrial Supply, Inc.

Soil Sement

Polymer Emulsion.

Normally sprayed onto surface to seal contamination in place. Has been used inside buildings to capture asbestos, beryllium, and radioactive contamination. It is easy to apply and dries to a hard surface. Can be applied with fire hose, which makes it easier to spray large areas. It is more expensive than other dust control agents.

Fixative does not wash off easily with water or rain. Fouls operating mechanisms and fasteners. Does not contain sugar, which would attract critters.

Used at Building 233-S at Hanford. Contractors mix at 10:1 ratio of water to Soil Sement for covering soil. Ratio is 4:1 for inside buildings.

Sanchem Inc. www.sanchem.com

Safegard

5022-A

Water and Glue.

Normally sprayed onto surface. Seals contamination in place.

Fixative does not wash off easily with water or rain. Fouls operating mechanisms or fasteners. Does not contain sugar, which would attract

critters. Used at Hanford Tank Farms

Bartlett Services, Inc

Polymeric Barrier System (PBS)

PBS is a non-toxic, water-based solution which forms an impermeable barrier between hazardous or contaminated materials and the environment.

Can be applied by industrial spray equipment, paint rollers, or brushes. Seals contamination in place. Need proper ventilation.

Commonly used to stabilize large components, concrete, valves, and other problematic radwaste equipment prior to shipment

Very hard to remove. Can be diluted with water. Seals bare lead to keep it from oxidizing. Has been used to “cocoon” large items that have to be left outside or shipped. Used at ORNL on outside of a metal Quonset Hut to seal contaminated flaking paint, prior to demolition.

TLC Stripcoat

Temporary Layered Strippable Coating that is non-hazardous, non-toxic, water-based solution designed to safely remove and prevent the spread of contamination.

Can be sprayed, rolled, or brushed. Several light coats recommended. While curing, Stripcoat mechanically and chemically entraps contamination.

DeconGel 1101, 1120 and

1121

Cellular Engineering, (808)

208-2208

http://decongel.com/product

-docs.html

See examples at website

Temporary layered strippable coating. Can be applied by paint brush, trowel, etc. 1 to 24 hour drying time before it can be stripped. Can be thinned with water. Each product has a different viscosity.

Decon Gel 1120 has been sprayed with Wagner Power sprayer at 7.2 GPH Wide Shot Max w/1 mm tip. Decon Gel 1121 has been applied with Graco UltraMax 795 @3300 psi, 0.095 GPH w/0.021” tip.

Easy to remove. A nuclear power plant favorite because it will not harm plant systems. It can be applied to horizontal, vertical, and inverted surfaces. When dry, the product locks the contaminants into a polymer matrix. Has 12 month shelf life.

Decon Gel cleans out any old paint left in the spray gun and this can cause plugging.

Typically, non-porous surfaces require 1-2 coats and semi-porous surfaces require 3-4 coats.

Rust Doctor

www.therustdoctor.com

Water based latex paint.

Can be sprayed, rolled or brushed on. Seals loose contamination in place when it converts from rust to magnetite.

This unique product chemically converts rusty metal to black magnetite, which is a very hard form of iron oxide. Very hard to remove.

Used at Hanford by BHI at 100N to fix contamination inside large steel tank before demolition. When the Rust doctor was applied on the rusty, contaminated surface, the loose contamination became fixed when the rust changed to black magnetite.

Instacote Inc. www.instacote.com

Instacote CC WET

Water-based Anti-dusting Media.

Stabilizes radiological, beryllium, asbestos and other hazardous contamination.

Spray as a fine mist to reduce airborne contamination in accessible and inaccessible locations.

Seems to be similar to glycerin and water. Used as a first step in a two step approach to fix contamination.  Once the surface has been stabilized using CC Wet, another fixative like CC Fix can be applied. This rehydrates the loose contamination and it’s adsorbed into the matrix of the fix. This leaves a hard coating.

Instacote Inc www.instacote.com

Instacote SEFR

A Polyurea coating used in the construction of low level waste shipping packages. to control the spread of contamination. Used in areas with heavy traffic, impact, or harsh environmental conditions.

SEFR is used to restore the structural integrity of compromised waste packages, such as Sea Land containers, Intermodals and other waste containers.

Instacote M-25

M-25 is a Polyurea used to control contamination in industrial facilities. It can also be used to control contamination in soils and surfaves that are exposed to harsh environmental conditions.

It can be used to protect clean surfaces from becoming contaminated during the D&D process.

Contaminated areas that are exposed to harsh environmental conditions will be controlled for long periods using M-25 polyurea. When applied over geotextile fabric, M-25 provides a hard, water-

proof “soil cap” that lasts for many years.

M-25 is provided in kits. A kit consists of one 55-gallon drum of isocyanate “Part A” and one 55-gallon drum of resin “Part B”. InstaCote provides a “turn key” service for the application of M-25, or they can train your work force to spray the product.

Soil Conditioner:

AgriGator Terra Bond www.pildyshtech.com/terra- bond.htm http://www.agrigator.com/L ABELS&MSDS/GatorLabel. pdf      www.agrigator.com Sold by America West at (509) 547-2797

Water based anti-dusting media. Company will mix additives to lower cure temperature, prevent freezing, and make more pliable. Spray applied. Effectively controls visible dust emissions & potential spread of contamination.

Product comes in liquid form and is easier to dilute than Soil Sement in dry form, and results in more consistent mixtures. Much cheaper than other fixatives.

Used for general dust suppression

D&D Emulsions www.ddemulsionsinc.com 419-525-4988

D&D Emulsions (419) 522-9440

Dust Bond

Dust control product that is formulated using a virgin adhesive petroleum resin suspended in a stable emulsion.

Sprayed. It penetrates, saturates, and bonds surface dust for a dust-free resilient surface. Used for heavy-duty dust suppression at Hanford in the 100 areas. It is diluted with water for spraying.

The cohesive resins penetrate the soil surface and attach themselves to the dusty fine particles, clustering them into particles that are too large to become airborne. The clustering of the particles aids in binding loose contamination and stabilizing the soil for easier excavation.

Dumond Chemicals Inc www.dumondchemicals.co m

They are a unique, versatile penetrating encapsulant used for porous sprayed on asbestos/soil.

Rapidly saturates loose or friable asbestos fibers, curing to a tough coating.
