EMFIMASTIC PU COLTUILE is a fast moisture curing one component sealant based on polyurethane, which forms a highly flexible, tear and weather resistant joint.


EMFIMASTIC PU COLTUILE is specially designed to bonding canal tiles.
Easy to apply, it adheres without any primer to most usual substrates : glass, anodized aluminium, most lacquered metals, wood, polyester, concrete, etc.


Substrates preparation :
The substrates must be clean, dry, free of dust, oil, grease and any contaminants that could harm bonding.
Clean them if necessary with EMFINET 683, methylethylketone (MEK) or acetone.
Check the compatibility of the solvent used with the substrates.
When using solvents, extinguish all sources of ignition and carefully follow the safety and handling instructions given by the manufacturer or supplier.
If necessary, rub down metal surfaces beforehand. Clean them after rubbing down.
Allow the substrate to dry after degreasing.
We recommend to clean concrete with a metal brush.

Caulking :
EMFIMASTIC PU COLTUILE can be applied by a manual or pneumatic gun.
After application, use a wet putty knife to smooth the joint.
This product should be used within 24 hours of opening the cartridge protection ; otherwise, the sealant could harden inside.
Do not apply at a temperature under 5°C.
Avoid any contact with non-cured MS, hybrid PU or silicone sealants as well as with alcohols or ammonia during curing.

Cleaning :
Tools may be cleaned with EMFINET 683, MEK or acetone before the sealant has completely cured. After curing, abrasion is necessary.
