Syntech HAG Mono

Low viscosity hydro-expansive single-component polyurethane resin

Resina poliuretanica monocomponente idroespansiva (non necessita di catalizzatore e aumenta il proprio volume iniziale di circa 3 volte), esente da solventi, ideale per sigillare, mediante iniezione, piccole e grandi infiltrazioni d'acqua nel calcestruzzo o nelle murature piene in genere. Ideale per colmare grandi vuoti e vespai interni alle murature. Reagisce con l'acqua e forma una schiuma flessibile a cellule chiuse. Sviluppato per l'applicazione in strutture umide e asciutte.

    Syntech HAG Mono

    • Thanks to its flexibility, the foam is able to partially absorb the movement of the crack.
    • Penetrates deeply even into thin cracks.
    • Does not need any additional catalyst to react with water.
    • Reacts with water to form carbon dioxide gas. This gas produces a swelling pressure and the resin expands into a dense closed-cell foam, sealing all water penetrations.
    • Free expansion: ± 300%
    • Good general chemical resistance.


    Fields of application

    Stops water infiltration into underground rooms. Ideal for sealing small cracks and fissures in concrete and solid masonry in general.


    Allowed supports
    Concrete
    Prefabricated concrete
    Bricks
    Mixed walls (bricks and stones)
    Stone walls
    Rock walls
    Preparation of supports

    The application surfaces must be clean, free of dirt, crumbly and inconsistent parts, dust, moss, mould, etc.. Prepare the appropriate injectors, usually arranged in a "quinquonce" pattern (from one side of the discontinuity to be sealed to the other). Inject plenty of water into the discontinuity beforehand until it is saturated (if not already present).


    Mode of use

    Manually mix the product thoroughly in its packaging to make it homogeneous. Keep in mind that the resin may react with the same ambient humidity. Syntech HAG Mono resin can be injected with a single-component resin pump, manual or electric, at variable pressures between 40 and 200 bar. The reaction speed depends on the amount of water that is inside the structure or that is introduced before the resin. At the end of the operations, always carefully clean the pump used with Nitro thinner and the specific Syntech HAG Cleaner lubricating detergent.

    Warnings

    Syntech HAG Mono is physiologically harmless once the reaction has taken place. The product is packaged under dry nitrogen and is very sensitive to humidity, including environmental humidity. It is recommended to use a small quantity at a time and carefully close the cans before putting them to rest. Make sure the injectors positioned in the supports are securely held. Given the high injection pressures reached by the pumps, in the case of injectors not positioned firmly and correctly there is a real risk that they could escape from their seat at high speed (with the risk of injury to the operators!). Carefully study the positioning of the injectors near the wall discontinuities to be injected. Poor positioning, too close to the crack to be filled, under the pressure of the pump can cause the support itself to break. Be very careful when using electric pumps, which can easily reach 200 bar pressure, and therefore cause unwanted breakages of the concrete and masonry supports being injected. Remove resin residues coming out of the walls within a few hours after the infiltration has stopped. Delayed removal may be more difficult.
