STAUF PUM-950 Power-Mastic provides a tremendous improvement for urethane adhesives. It is a urethane-based, high-strength adhesive for professional wood flooring installation. But unlike other Urethane adhesives, it contains no isocyanates, the primary chemical in other urethane adhesives that will etch fine floor finishes and are a suspected carcinogen. Nor does it contain any solvents or other hazardous materials. It is, therefore, safe for the ozone and the environment. And it is certified to meet some of the toughest "green" product requirements in Europe and the world. It qualifies for LEED credits.
