Alara TM 1146 Strippable Coating

Category: Decontamination > Surface Cleaning > Strippable Coatings
Reference # : OST/TMS ID 2314, DOE/EM-0533 Model No : 1146

The ALARA 1146 strippable coating is a water-borne vinyl butyl, which can be sprayed, rolled, brushed, or pour squeezed onto the surface to be decontaminated in the same manner as paint. The coating is free of solvents and toxic materials. Applied over a contaminated surface, ALARAT 1146 strippable coating migrates into micro-voids of the surface to contact and bind surface contaminants. Upon curing, the product mechanically locks the contaminants into a polymer matrix. Removal of the film decontaminates the surface and produces a solid waste: Removal of the strippable coating from the surface after curing involves stripping or pulling the coating away from the surface. To facilitate its removal, the coating can be scored into large sections with a sharp knife. The coating can be rolled as it is removed for ease of handling and to further trap any residual contamination on the surface of the coating. The ALARAT 1146 can be applied to bare and painted concrete, wood, carbon and stainless steel, plastic, and insulation. Dimensions of Tech Model (LxWxH):Weight of Tech Model (lb.):

Benefits

The ALARA TM 1146 strippable coating is an effective product for the removal of surface contamination. The use of strippable coating is specially applicable for facilities with a need to minimize the amount of the liquid waste generated during decontamination activites. Reduces solid waste - dried coating can be incinerated. Immobilizes surface contamination. Adheres to and easily removable from complex surfaces and components. Rapid application and removal.

Limitations

The ALARA TM 1146 strippable coating would benefit from the following design improvements: A drying time of less than 24 hours would potentially improve worker productivity.
