Polyurethane coatings
BIOGO-WS
Water-Based Polyurethane
Single-component · water-based flexible membrane
A low-odor water-based polyurethane coating available in UV-resistant and protected grades.
Product overview
Product overview and technical properties.
BIOGO-WS is a single-component, water-based polyurethane waterproof coating formulated with an aqueous polyurethane dispersion, pigments, fillers and functional additives. As water evaporates, it forms a flexible, continuous and durable waterproof membrane on the prepared substrate.
