Protech Flex

Polyurethane sealant in a cartridge with a high modulus of elasticity

A single-component, moisture-curing and fast-hardening polyurethane sealant with a medium-to-high modulus of elasticity, remaining permanently elastic yet with high surface hardness and being tear- and weather-resistance and paintable. Ideal for the deformable sealing of expansion joints on terraces and balconies, for filling joints on prefabricated walls and on wooden, steel, aluminium, copper and plastic materials along with plasters and so on.

    Preparation of supports
    The application supports must be perfectly clean and dry, free from dust and soiling. Preliminarily treating the side walls of the joint with the appropriate primer single-component polyurethane Protech Flex Primer.

    It is appropriate to provide for inserting into the joint, whatever its nature, the specific foamed polyethylene kerb Filtene Fondogiunto, of the appropriate size to the joint to be sealed.

    Prepare an easily removable paper ribbon (coachbuilder ribbon type) on both sides of the joint, in order to prevent the sealant overflowing outside of the natural seating of the joint.

    Mode of use
    Slowly and carefully extrude the sealant from the cartridge in the specially prepared seat of the joint, with the appropriate gun (of the type for silicone). Before the total hardening of the sealant, spread it to the brim with spatula on the surface of the joint. After hardening, remove the adhesive tape.

    Clean any product overflows from the seat of the joint with suitable solvents (like acetone or Nitro thinner).
