EMFIMASTIC HIGH POWER is a single component high-viscosity elastomeric sealant, based on silane terminated polymer and presenting high immediate bonding properties.
After application, it cures under the effect of moisture present in the air or in the substrates to form a flexible joint presenting a high resistance to tear.


EMFIMASTIC HIGH POWER can be used in the building and general industries, indoor or outdoor, to bond elements which may be subject to vibrations or deformations.
The adhesion is excellent on a wide range of substrates commonly used in the building industry (tiling, glass, wood, PVC, pre-lacquered aluminium, most of the metals, polystyrene, stone, polyester, concrete, etc.)
However, due to the large variety of substrates, suppliers and installation conditions, it is necessary to make tests beforehand on difficult materials (particularly on non-ferrous or lacquered metals and plastic substrates like PVC, PMMA or ABS) to determine whether abrasion or the use of a primer may be necessary to improve adhesion.
For further information, contact our technical department.
Not suitable for substrates like PE, PP, Teflon, wallpaper-glass cloth.
Avoid any contact with oils, plasticizers or products like bitumen, asphalt, silicone, etc.


Substrate preparation:
The substrates must be clean, even, dry, dust free and not have any traces of grease or other contaminants that could harm bonding.
If the substrates need to be cleaned, use EMFINET 683, methylethylketone (MEK), acetone or SAPOCOL GR 1001 degreaser.
Check their compatibility with the substrates.
It is recommended to rub down concrete, particularly cement film residue, with a metal brush. After scraping, remove the dust. On concrete, if the surface is poorly cohesive, apply primer EMFIPRIM PU 2001.
If necessary, rub down metallic surfaces beforehand (especially in presence of oxidation). After rubbing down, clean them with a solvent and allow to dry for at least 10 minutes.
If necessary, apply a primer - contact our technical department if needed.
Note: when using solvents, extinguish all sources of ignition and carefully follow the safety and handling instructions given by the manufacturer.

EMFIMASTIC HIGH POWER can be applied by a manual, pneumatic or electrical gun with a triangular nozzle (supplied with the cartridge), in ropes spaced out from 5 to 10 cm, depending on the substrates.
It is possible to apply heavy materials vertically without any mechanical holding.
However, for heavier elements, a mechanical holding before curing is required.
This product should be used within 24 hours which follow the opening of the packaging; otherwise the sealant could cure.
Avoid any contact with non-cured polyurethanes during curing.

Tools can be cleaned with EMFINET 683, MEK, acetone or EMFICLEAN AL wipes before the sealant has completely cured. After curing, abrasion is necessary.
Hands can be cleaned with EMFICLEAN AL wipes.
