Polyplex radon gas sealing. Two-component sealant

Polyplex radon gas sealing

Polyplex radon gas sealing www.denber-paints.co.il

Characteristics:

Prevents the passage of gases in general and radon gas in particular.
100% solids, does not contain solvents/thinners, can be applied in closed places without odor and without solvents in the air.
Flexible extends by at least 150% and bridges capillary cracks.
A perfect seal against the passage of gases and water.
The strength of its adhesion allows a multi-thickness coating in one thick casting from 5 mm on walls to 5 mm or more on concrete floors.
Ready for repainting and/or coating the same day and even within a few hours in the summer.
A very dense chemical structure that prevents the passage of gases and water.
Resistant to blows and scratches and heavy loads.
Resistant to heat up to 100 degrees and cold to minus 50 degrees.
High electrical insulation.
Hard to tear and easy to repair in case of damage.
Sealing asphalt surfaces through which gas seeps from underground gas tanks.

uses:

To prevent the penetration of radon gas through the walls or through the floor of underground concrete buildings, shelters, basements, bunkers, etc.
Thick coating in one pour of concrete floors in civil, industrial and military shelters or underground structures.
Coating of underground ammunition warehouses, including those where forklifts and heavy vehicles travel.
For internal and external coating of gas tanks.
For coating welding seams in piping and containers to prevent leaks.

Technical data:

Theoretical coverage – 1 liter per 2 square meters on a smooth wall. 2-5 liters per square meter for floors depending on load resistance requirements.

Abrasion – 120 micron – 2500 cycles (Gardner) ASTM
Recommended layer thickness – no thickness limit, but in walls with a roller thin layers of 100-200 microns without leakage and up to 500 microns in total to guarantee the prevention of gas penetration.
Recommended number of layers – floor: in one thick layer, walls: in several thin layers until a total thickness of 5 mm is obtained.

Compressive strength – 800 kg/cm2
Tensile tear strength at a speed of 100 mm per minute – 60 kg/cm2 (ASTM D-412)
Adhesion to concrete – more than the strength of the concrete.
Electrical insulation level – X10 ¹⁴ 5 ohms/cm3.
Minimum ripening time – 24 hours
Final ripening time for exposure to chemicals – 7 days.
