Connecting radiation-protective mastic Abris RZ

Abris RZ - radiation-protective polymer mastic for joints of various structures made of lead, concrete, etc. (TU 6990-012-52471462-2009)

Mastic Abris RZ is a plastic or paste-like non-curing mixture based on a polymer binder, filler, plasticizer and technological additives. Barite, lead, and tungsten are used as fillers. The waterproofing properties of the Abris RZ material are provided by a polymer base. In addition, the applied polymer base of the Abris RZ material ensures the resistance of the material to seawater, chemically aggressive environments (solutions of salts, weak acids and concentrated alkalis).

Mastic Abris RZ is available in the form of self-adhesive tapes and cords, as well as in cartridges and in file packages.

Mastic materials Abris RZ are used:

1. For sealing slotted holes, output communications (mastic in cords, in cartridges, in file packages).

2.For sealing the docking points in structures made of lead, steel, concrete, combined protection (mastic in the form of tapes, cords with various fillers).

3. For the rehabilitation of cracks in concrete. The consistency of the mastic allows you to apply it with a spatula.

4. When installing barite panels, Abris material is used (mastic in the form of tapes with various fillers) for sealing joints between panels.

5. For the arrangement of premises in the form of profiled materials:

a set of parts (flat sheets) of the required thickness, width, length;
flexible roll materials (roll width up to 500 mm, roll length up to 10 m.);
it is possible to supply material with reinforcement (hard plastic, metal, PVC, etc.).
