NuPLUG 2140 R Foam

Introduction
The NuPLUG 2140 R* Foam is a flexible product used as both a radiological barrier and as fire break to caulk electrical and mechanical penetration assemblies, in addition to sheaths cast in both concrete slabs and walls.

* Also named 935.BC

Product Data
- Bi-component silicone foam
- Shielding factor for gamma radiation, X-rays and neutrons equivalent to that of concrete
- A flexible product that makes it possible to insert extra penetration modules in penetration assemblies that have already been caulked
- Acts as a fire break for up to two hours (EI 120) (Tested according to the 2004 French decree and the EN 1366-3 standard)
- Product used for caulking penetration assemblies with a saturation level of sixty percent
- Product can be imbued with sealant and decontaminable properties if coated with a paired MECATISS product such as NuCOAT 7110 I (SILCO Fabric) or NuCOAT 3110 I (TSR 750)

Operational Information
- Minimum thickness: 150 mm
- To be used on clean, dry and degreased surfaces
- - 3 possibilities for implementation:
o Pneumatic pump (for large volumes)
o Manual or pneumatic caulking gun (for the filling of small volumes)
o Manually, through the use of gravity (for easily accessed volumes)
- Setting time: < 15 min
- Complete cross-linking: 24 hours
- End product density (polymerised): 2.4 to 2.6

Other Technical Information (Packaging, storage)
