Radiation-protective mastic Abris RZm

Packaging: metal barrels, cans, plastic buckets
TU: 6990-012-52471462-2009

 Mastic in the form of a homogeneous paste-like non-hardening mass with a special filling, applied with a spatula.

Radiation-protective mastic Abris RZm

Color - from white to dark gray.

Application area:

radiation protection against ionizing radiation, for sealing and anti-corrosion protection in problem areas (joints, utilities, cable entries, etc.);

Characteristics

 Colour: White to dark gray

 Release form: pasty mastic, non-hardening, with special filling.

Depending on the type of fillers, the mastic is produced in two grades: mastic Abris RZm-01 (barite-filled), mastic Abris RZm-02 (lead-filled). Designed for filling protective devices (tanks, containers, cassettes of various configurations) that provide radiation protection of objects, as well as for sealing shallow (less than 10 mm) cracks and slotted holes.

Mode of application:

 Temperature conditions of operation from -40 °С to +70 °С. Depending on the required lead equivalent to protect the object, the mastic thickness is calculated, taking into account its lead equivalent. Before applying the mastic to a concrete or brick surface, it is necessary to strengthen the loose crumbling areas of the surface. When filling the internal parts of the protective devices, pumping equipment for high viscosity systems is used. The filling quality of protective devices is controlled by theoretically calculating the amount of mastic required to fill the desired volume. A spatula is used to seal cracks and slotted holes. Compaction of the mastic is carried out by pressing the material into hard-to-reach places. To increase the fluidity of the mastic, its manufacturability and exclude air voids when filling cassettes and containers, it is possible to use mastic heating up to (70-100)°C. To heat the mastic, you can use thermal equipment such as: heat guns, electric heaters, water baths, etc. It is forbidden to use an open flame to heat up the mastic! Work should be carried out in rubber gloves, away from open sources of fire, in well-ventilated areas or in the open air. The radiation-protective material Abris RZ does not form toxic substances during application and operation, and does not have a harmful effect on the body. Consumption of mastic Abris RZm-01 with a layer of 1 cm is 18 kg per 1 m², mastic Abris RZm-02 - 37 kg per 1 m².
