Description
Water based 2K polyurethane systems are a new technology which is already successfully used in many applications also for wood coatings and more specifically furniture finishes, without having to sacrifice quality. Some properties like the ease of introduction by hand of the hardener and the determination of the pot-life through the viscosity increase can be optimized by choosing the right solvent to dilute the polyisocyanate.
