Metis Scientific says that its product DG Sure has been approved for use in some nuclear plants in the UK.
DG Sure was formulated specifically to adhere to the UK’s disposal regulatory requirements and therefore could be used at other facilities throughout the UK and European Union.
The company says the product is void of chelators and has low levels of halides and sulfides. The product has almost a year of testing as part of the approval process.
DG Sure is a polymer-based hydrogel with unique binding properties. Upon application, the coating penetrates into contiguous microscopic surface pores, mechanically binding and encapsulating surface contaminants in a semi-crystalline polymer matrix. Upon drying, the film can be peeled away, safely remediating the underlying surface and allowing for the effective disposal of a reduced waste volume.
The company says some of the attributes of the material are:
- Easy application, high decontamination factor
- Safe to use and handle
- Nonflammable, water-soluble
- Compressible, biodegradable
- Non-destructive to most surfaces
- Locks decontaminants with no spreading
- Reduced waste volumes (in excess of 90 percent in some cases)
- Reduced labor requirements
DG Sure may be used on all hard surfaces including bare, coated, or painted concrete, metals, plastics, rubber, glass, wood, porcelain, stone, grouts, ceramic, linoleum floors and others.
The product can be applied by brush, trowel, roller, or sprayer (if diluted with water). The gel, dry or wet, can be disposed of as regular waste. However, the dried gel and the contamination encapsulated in and around the gel must be disposed of according to local/national regulations.
