Product overview

Product overview and technical properties.

BIOGO-S is a single-component, reaction-type moisture-curing polymer waterproof coating made by addition polymerization using isocyanate and polyether polyol as the principal raw materials, together with selected additives and fillers. After application to the prepared waterproofing substrate, the terminal -NCO groups in the polyurethane prepolymer react with moisture in the air to form a tough, flexible and seamless rubber-like waterproof membrane over the substrate surface.

Transport and Storage

Protect the storage area from sunlight and rain, keep it ventilated and away from fire.

Store at 5–40°C.

Shelf life is 1 year from the production date under normal transport and storage conditions.

Suitability depends on substrate condition, exposure, climate, detailing, film build and the approved project system. Complete a representative adhesion and compatibility trial before full application.
