Surface Preparation
Surface must be clean, smooth, dry, and free of wax, grease, oil, loose or peeling paint, and other foreign material.

A part and B part must be mixed homogeneously prior to application, using an electrical or pneumatic power stirrer until a homoge-homogeneous mix is achieved.

PENTENS NPU-12 should be applied to the prepared surface by using brush or lamb wool roller or spray equipment.
The second coat may be applied as soon as the first coat has initially dried (typically 4 to 6 hours). The time will be dependent on the type of surface and the ambient conditions.

Approximately 6~10 square meters per kg, depending on the porosity of the substrate.​


Impervious gloves and barrier cream should be used when handling these products.
Eye protection should be worn. In case of contact with eyes, wash thoroughly with plenty of water and seek medical advice if symptoms persist.
If contact with skin occurs, it must be removed before curing takes place.
Wash off with an industrial skin clearer followed by plenty of soap and water. Do not use solvent.
