PU Liquid Membrane Proofing

Description:

A high performance PU based with permanent elasticity properties, one component ready to use by spray or roller brush results in good UV resistance and high mechanical strength, high thermal resistance and chemical resistance. It is a solvent based polyurethane liquid-membrane which is cold applied and cures naturally.

Properties:

It is suitable for cementitious surfaces, rooftops of ware-houses , metallic joints protecting bridge-decks, tunnels, pedestrian-decks Concrete buildings, sheds warehouses, metal joints, concrete joints roof tops, automotive exterior roof top coatings like buses, ship building, railways & metros.
