Polyurethane coatings
BIOGO-AS
Solvent-Free One-Component Polyurethane
Moisture-curing · high-solids elastic membrane
A clean, low-odor polyurethane waterproof coating for non-exposed roofs, underground works and enclosed projects.
Product overview
Product overview and technical properties.
BIOGO-AS is a reactive, moisture-curing polymer waterproof coating based on isocyanate prepolymers and polyether polyols, with selected auxiliaries and fillers. After application, the terminal -NCO groups react with atmospheric moisture to form a tough, highly elastic, flexible and seamless rubber-like waterproof membrane.
