ISOLEMFI 3100 MONO

One-part polyurethane-based moisture curing adhesive.
D4 water resistance classification according to European standards EN 204 and EN 205.

APPLICATION AREAS

Bonding of outdoor joinery requiring very good resistance to humidity. Bonding of exotic and greasy woods. Miscellaneous bondings in boat fittings.
Bonding of wood, plaster, plasterboard, metal, bricks and concrete on themselves or with each other on the condition that at least one of these materials contains moisture.
Bonding of rigid insulating foams like extruded or expanded polystyrene, phenolic foam or of mineral wool panels on plaster boards with or without vapour shield, fibre cement, chipboard panels, steel sheets and wood.

MANUAL

Substrates preparation :
The substrates to be assembled must be flat, dry, dust free and not have any traces of grease or other contaminants that could adversely affect the bonding performance.
If the substrates need to be cleaned, EMFINET 683 or methylethylketone (MEK) may be used. Solvents must comply with local regulations. Check the compatibility of the solvent used with the substrates. If necessary, rub down metal surfaces beforehand.
When using solvents, extinguish all sources of ignition and carefully follow the safety and handling instructions given by the manufacturer or supplier.
Application :
The adhesive is applied on one of the substrates to be bonded with a brush or a serrated spreader.
One of the materials to be bonded must be porous or contain moisture.
In case of two non-porous materials, spray a light water mist (10 to 15 g/m²) onto the adhesive film.
The setting time depends on hygrometry and temperature. So it is necessary :
- in case of working under 20 °C : to be sure that the pressing time is long enough
- in case of working over 20 °C : to be sure that open time is not excessive
Otherwise, defective bonding could happen.
Assembling has to be followed immediately by a uniform pressure applied across the entire surface. A strong pressure is not necessary but the materials must stay in full contact during setting time.
Cleaning :
Tools can be cleaned with EMFINET 683 or MEK before the adhesive has completely cured. After curing, abrasion is necessary.
