DeconPeel_4580 : Temporary Protective Removable coatings For Decontamination , Strippable Coatings For Nuclear decommissioning
|
|
|
|
|
| |
Our DeconPeel coatings are
formulated to protect your nuclear facility by
reducing hazardous residues. Deconpeel are
peelable coatings and are proven products. They
are innovative, economical and easy-to-use. In
addition, their non-toxic composition ensures
their safe application and easy disposal.
Strippable Coatings. With this
process a plastic membrane or coating
(such as polyethylene, or large number of small,
spherical silicon carbide pieces
polyvinylchloride) is put on the contaminated
surface. attached to the ends of a corresponding
number of This coating material is best applied
with a brush-stiff nylon bristles. The resulting
coating is peeled off, loose surface
contaminants are removed with the coating.
Strippable coatings are also often used to
prevent the recontamination of decontaminated
surfaces. This process has been extensively
used in the nuclear industry.Temporary Protective Water Resistant Peelable Coating, Protects: Metals, Glass, Acrylics. Enamels And Other Surfaces. Water reducible. VOC Free.Water Resistant Peelable coating for various applications to temporarily protect surface from exterior and interior environment , prevent damage and scratches including glass, good sag resistance spray through Air Assisted conventional spray equipment . Low temperature curing and low viscosity
process of developing
methods to decontaminate a
process hot cell that has a
film of residual solids left
after the evaporation of
Hydroflouric Acid, Boric
acid, Nitric Acid and
Aluminum Nitrate chemicals
that contained relatively
high concentrations of
dissolved cadmium, boron,
uranium and zirconium.
Deconpeel can be used
to help strip off and
minimize the contamination
on walls and floors made of
welded stainless steel.
Customer Inquiry : Nuclear application -
a strippable coating to bind
up and help remove
solidified residuals of the
following liquids: Zirconyl
Nitrate in 2M Nitric Acid;
Aluminum Nitrate 2 M with 30
g/L cadmium Nitrate;
Hydrofluoric Acid with 12
g/L Boron, cadmium sulfate,
Nitric Acid 13M with 30 g/L
cadmium nitrate. These
acids would have zirconium
alloys, uranium and
transuranic isotopes
dissolved in them. The
materials have dried to a
crystalline powder on sst
and hastaloy surfaces.
Also, small volumes of these
liquids will be spilled on
the applied coating over a
period of 12 months prior to
removal.
Do you have a coating that
can be applied over a wet
surface? There appears to
be a wet layer at the bottom
of some of the thicker
layers of these materials.
Also, we may wash down the
surfaces with high pressure
water prior to applying the
coating and do not have a
good means of drying the
surfaces other than allowing
the ventilation flow to dry
it out over time. The
radiation levels are
relatively high so this
coating will need to be
applied be sprayer using
remote manipulators.
Customer Inquiry :"I
am in process of developing
methods to decontaminate a
process hot cell that has a
film of residual solids left
after the evaporation of
Hydroflouric Acid, Boric
acid, Nitric Acid and
Aluminum Nitrate chemicals
that contained relatively
high concentrations of
disolved cadmium, boron,
uranium and zirconium. Do
you have a product that is
compatible with these
chemicals to use to help
strip off and minimize the
contamination on walls and
floors made of welded
stainless steel? " |

Application: Temporary Protective Removable coatings For Decontamination , Strippable Coatings For Nuclear decommissioning |
|
|
|
|
|

DeconPeel 4580 is normally used as received. It can be applied by spray, roll or brush . DeconPeel 4580 may also be diluted at the rate of one to four ounces of water per gallon or as needed for proper application. The sprayed coating dries, depending on the film thickness, in 30 minutes to 4 hours. DeconPeel 4580 should be applied to yield a dry film from one to ten mils (.001" to .010") thick. The coating, when totally dry, is resistant to water and some solvents used in paint. Application temperatures range from 120º F. for fast force cure to no lower than 45º F. DeconPeel 4580 cures upon water evaporation. Faster cure can be realized by placement of air fans to remove the water from the coating. The coating when applied is milky but when cured is totally transparent. The milky appearance is indicative of water presence in the coating. Brushes, rollers and spray equipment can be cleaned with water immediately after coating application. The coating becomes water resistant when clear . |

Removal: |
|
|
| |
DeconPeel 4580 is removed by peeling. Simply, pry a piece of coating in one corner and lift.

|
|
|
|
|
| |
 |
Flammability: |
|
|
| |
Water Resistant DeconPeel 4580 presents no fire hazard as received, during, or after application.
|

|
|
|
|
|
|
|
|
|
| |
 |
Disposal: |
|
|
|
|
|
| |
DeconPeel 4580 is formulated to exclude ingredients that are deleterious to the painting process, such as silicones, or to the water wash system, such as foam generating or foam stabilizing ingredients. |

 |
Operating Guidelines: |
|
|
| |
|
When applying, use the same protection as used while applying paint. The booth ventilation stem should be operating while the material is being sprayed. |
|
Chemical goggles and impervious gloves should be worn when handling DeconPeel 4580. |
|
Use of non-sparking metal equipment is advised when scraping to remove booth coatings, to avoid fire hazards from the accumulated paint. |

First Time Application: |
|
|
| |
I. Cleaning of Equipment: |
|
|
|
|
| |
To clean the pressure pot, airless equipment, spray guns, or spray lines: |
|
|
|
|
| |
|
Flush equipment and lines with the current paint thinner (toluene, xylene, or mek), |
|
Follow with a water reducible solvent, such as butyl cellosolve. This will help to remove any solvent residue. |
|
Thoroughly rinse with water. Making sure that all solvent and paint residues are removed. |
|
|
|
|
|
| |
II. Cleaning of spray booth walls: |
|
|
|
|
| |
To clean all surfaces where DeconPeel 4580 is to be applied: |
|
|
|
|
| |
|
Clean surface with butyl-cellosolve type cleaner. |
|
Remove all previous peelable coatings, oils, dirt, and solvent residue from the surface.
NOTE: You do not have to do this cleaning step to have DeconPeel 4580 peel or rinse off the surfaces. This procedure can be eliminated after the second and all subsequent applications. |
|
DeconPeel 4580 can now be applied. |
