A single pack moisture curing polyurethane pre-polymer. The pre-polymer converts to a tough flexible film over a wide range of temperatures and humidity after exposure in thin films for 6-8 hours. Primary use is as a membrane to control evaporation of moisture from the substrate of new concrete, and thus to increase strength. This membrane effect is of great importance, but the value of 779-Polyurethane Concrete Floor Seal as a sealer and binder of older concrete surfaces should not be under estimated as a coating will strengthen a dusting surface making it easier to keep clean, and reduce penetration of stains.
The type of industries which would benefit from this type of sealer:
Food preparation areas ease of cleaning
Printing plant floors non dusting
Automotive Engineering non dusting and non staining
Computer floors Moisture control
