POLYMASTIC 1 is a one-part adhesive based on synthetic elastomers and non-aggressive solvents towards polystyrene.
POLYMASTIC 1 has a strong setting after evaporation of solvents and a good water resistance.


POLYMASTIC 1 can bond expanded or extruded polystyrene in slabs or panels, common building insulating materials (mineral wool, polyurethane panels), decorative ceiling roses and cornices, wood or PVC skirtings on most porous and non-porous substrates.


Substrates preparation :
The surfaces must be even, clean, dry, free of grease, dust or anything that could that
could adversely affect the adhesive performance.
If necessary clean with solution EMFINET 688/1. Suitability between cleaning solvent and substrate
has to be tested beforehand.
If necessary rub down the metallic surfaces. Clean after rubbing down.
Let the surfaces dry after cleaning.
Note: When using solvents, extinguish all sources of ignition and carefully follow the safety and handling instructions given by the manufacturer.
Temperature of adhesive and substrates have to be between 10 and 30 °C.

Application :
POLYMASTIC 1 has to be spread with a spatula or in beads on the most rigid and smooth surface.
Put the materials into contact with each other to transfer the adhesive, then separate to let the solvents evaporate.
Verify if transfer is good.
After 10 minutes apply in pressing firmly. Bonding is definitive.
Definitive setting will be reached after 48 to 72 hours for insulating materials and 7 days for non-absorbing materials ( if evaporation of solvents was correct before definitive assembling).
