DeconPeel coating traps and encapsulates a wide spectrum of radioisotopes and chemicals in easy to apply , no requirement for pre-preparation process allowing easy and safe disposal without the use of water. When dry, the product locks the contaminants into a polymer matrix. The film containing the encapsulated contamination can then be peeled and disposed.

General chemical is a worldwide supplier of decontamination coating to reduce and clean up hazardous residues in nuclear facilities set a new standard of excellence. These proven coatings and cleaners are innovative, economical and easy-to-use. They are environment friendly, safe to apply and easy disposal. our products  will work in your  Nuclear Decommissioning, Decontamination and Reutilization projects.

The uses of DeconCoat can be considered in applications such as these:

1 To prevent contamination taking place on the surfaces of objects such as robots, glove boxes or modular containment systems which would otherwise become contaminated by low radiation dust particles.

The Deconcoat peelable coating is first applied to the clean surface and as this becomes contaminated by the ensuing process subsequent layers of Deconcoat are applied to encapsulate and tie down the contamination. The whole strippable film may then be stripped away for disposal as dry waste.  

2 Containment or tie down of radioactive contaminants. A Deconcoat Peelable coating is used to 'tie down' surface contamination on objects or areas being decommissioned, dismantled or removed for disposal. The coatings are available in a variety of colors for application by spray, roller or brush.

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? "

2.We are working in a facility contaminated with Tritium. We have to purchase a portable gantry crane to move some equipment around. Our client ( National Laboratory) wants to be able to reuse this crane in another facility afterwards and wants to minimize the decontamination efforts and the potential for not being able to release the crane to the other facility later down the road.
The crane is a typical gantry crane. That is, a horizontal top beam (steel) that holds the chain hoist mechanism) approximately 9 feet across and the end structures (all steel) tri-pod frames on castors for easy rolling. The crane can be adjusted to a maximum height of 12 feet. The moving parts consist of the hoist mechanism traveling across the upper horizontal beam. The chain in the hoist mechanism is the only other moving part. The paint will be applied primarily to the structure itself. We will probably cover the hoist mechanism in plastic to minimize contamination. We anticipate that we will have to perform some decontamination, but the idea is to try and keep the basic structure of the crane clean after stripping off the paint.
We realize that Tritium is different than other radioisotopes since it is not a particulate, but rather a gas. Nevertheless, the client wants the paint to try to minimize decontamination efforts.

Our Recommendation: Deconcoat  2050 is a water based peelable coating promoted for the protection of metal from rusting. This coating cures by water evaporation a goes from white to clear. The coating can be applied to metal, glass, marble and painted semi or glossy surfaces.

In this case, we suggest of applying a coat of  2050, about 6 to 10 mils, and start using your equipment. When the job is finished apply a second coat, sandwiching contaminates, and let the coating dry to clear state. Pry a corner and peel the coating off. Dispose of the coating and contaminates properly. Camel hair brush is the best.

3. we are a Finnish engineering company providing services and products for nuclear industry. Our client for which we have provided a decontamination system to clean walls of the reactor pool has now asked us to provide also a system to clean reactor vessel flange surfaces which can be seen in the photo attached. The areas to be cleaned consists of the floor area (25 m2 x 2 units) shown in the photo except the area covered with a blue plate. The bolt holes will be equipped with flat blinds during the cleaning.

We have learned that you provide strippable coatings for nuclear industry. We are interested in DeconCoat 2050 and we have couple of questions about it.

1. What is the price of six gallons of DeconCoat 2050?

2. What is the recommended way to apply DeconCoat 2050 to reactor vessel flange surface?

Our Recommendations : DECONCOAT 2050 is a water based peelable coating to be applied by airless spray to a minimum wet thickness of 12 to 14 mils. The product cures by water evaporation and transforms from white to clear. Clear coating is hard a flexible. The cure process encompasses most particles into the coating and can be disposed when Deconcoat is peeled.

Typical customer Inquiry: Dear Sir / Madam, Please could I have some more information (Tech data sheet, MSDS and cost) on your DeconPeel 4580? Is it suitable for use on concrete surfaces? If not can you recommend an alternative? We intend using it to 'tie down' contamination on the walls of a cooling pond located on a Nuclear site. Please contact me if you require any further information, Thanks for any assistance you can offer, Design Engineer.

"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 dissolved 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?"

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.
2. Typical customer Inquiry: Dear Sirs, We at the A Nuclear Power Station are in the middle of various de-commissioning activities on site prior to entering a long-term period of care and maintenance.

One of the next activities to be performed is the draining-down of the concrete built reactor cooling water ponds.

Our technical guys have suggested that there might be the need to apply a Temporary Protective Removable Coating to the wet concrete surfaces of the ponds after drain-down and power spray cleaning to contain any contaminated surface particulate and also prevent airborne contamination.

This temporary coating would later be peeled away taking any loose particulate with it to be replaced with a more permanent and hard-wearing coating.

We found your company name via the internet and in the first instance would be grateful if you could advise which office/contact point within your group would be the best recipient when we are ready to issue a further detailed enquiry.
If you can offer any suitable product(s) or other related advice etc then we'd be pleased to hear from you.
Our recommendations :4580 and 4000 are water based peelable coatings that can be applied to a moist concrete surfaces. Both products cure upon water evaporation. The cured coatings are clear(uncured coatings are milky)and water resistant.
Peeling can only be accomplished with cured coatings. We recommend a minimum of 12 mils of wet coating to accomplish good peel and debris pickup.
