PREPARATION OF PARTS FOR FILLING AND ASSEMBLY

• Clean the surfaces of parts to be filled with liquid compound with a wire brush to remove any dirt, chips, and rust. Sandblasting may also be used.
• Wipe the surface of the parts, cleaned with a wire brush, with clean rags.
• In winter, in order to speed up the polymerization process of the compound, it is advisable to heat the poured part to a temperature of +18+20°C.
• The ratio of components A and B of the compound is A: B - 3: 1 (by weight).
• Mix component A thoroughly with a spatula to remove any sediment, avoiding introducing large amounts of air, which could cause foaming. Therefore, the container containing component A should be hermetically sealed immediately after mixing or after removing the next portion. The container containing component B should also be hermetically sealed.
• Pour component B into the container with component A and mix thoroughly for 3-5 minutes, either by hand or with a drill and paddle mixer, avoiding air or undermixing, until a homogeneous mixture is achieved. Mixing should be done in a warm room at a temperature of 18 to 20°C, in close proximity to the assembly into which the mixture is to be poured.

Pouring and Curing

The time from the moment of surface treatment until the filling of the housing should not exceed 24 hours.

The composition prepared for pouring must be used immediately for its intended purpose, since the viability of the mixture does not exceed 30 minutes, after which the viscosity of the composite increases and the penetrating ability deteriorates.

Fill the assembly cavity using appropriate receiving devices, such as funnels, in batches no larger than 5 kg of compound. The interval between each batch should not exceed 15-20 minutes.

The completion of pouring should be judged by the exit of the compound from the hole opposite the one being poured.

Curing occurs within 4-5 hours, depending on the temperature during the curing process. The composite achieves full strength within 24 hours, after which the assembly can be used. After 24 hours, the compound also acquires chemical resistance.

SAFETY MEASURES

When working with the material in a closed space, ensure adequate ventilation, avoid open flames, and do not weld. The material may cause skin irritation. If ventilation is inadequate, wear personal protective equipment. If contact occurs with mucous membranes or eyes, rinse immediately with plenty of water and seek medical attention.

There are no harmful emissions into the atmosphere when working with the compound or during its curing. When cured, it is a non-toxic substance.

SEALING METHOD

• Quantity of compound S>= 20 mm.
• A= Sealed conductors.
• B= Two-component polyurethane compound.
• C= outer cable sheath.
• D= seal for IP protection.
• C min. 4 mm (sealing for outer cable sheath is required).
