Polyurethane is a type of synthetic material that is often used as a finish for hardwood floors. Its popularity is due to its impressive durability. Compared to other finishes, such as varnishes and shellacs, polyurethane stands out for offering a tougher and longer-lasting protective layer.
This resilient characteristic makes it a preferred choice in both residential and commercial settings.
Oil-based polyurethane traditionally dominated the market. It provided a robust finish that could withstand the wear and tear of daily use. However, its wide use brought about concerns due to the high levels of volatile organic compounds (VOCs) it emitted. This led to the development of more environmentally friendly options.

Volatile Organic Compounds, or VOCs, are chemicals that easily evaporate into the air, contributing to air pollution and posing health risks. Common in many household products, VOCs are known for their role in the formation of ground-level ozone, which can harm the lungs and is associated with respiratory illnesses.
These compounds have been a significant concern in the use of oil-based products like traditional polyurethane. As the binders in these finishes dry, VOCs are released, raising concerns over air quality and exposure to harmful chemicals inside homes and buildings. By reducing the VOC content in products, the negative impact on both indoor and outdoor environments can be minimized.
Water-based polyurethanes are part of this effort, substantially lowering the emission of VOCs by using water as the primary solvent instead of oil.

The Presidential Green Chemistry Challenge is a prestigious award given to innovations that incorporate green chemistry principles, aiming to protect human health and the environment. The award recognizes groundbreaking advancements that reduce or eliminate hazardous chemicals in the design, manufacture, and use of chemical products.
The Bayer Corporation received this accolade in 2000 for their development of a water-based polyurethane, as it marked a significant step towards reducing VOC emissions. This innovation exemplified how businesses could harmonize industrial needs with environmental protection.
By achieving a reduction in VOCs by 50-90%, Bayer's water-based polyurethane not only improved air quality but also showcased the potential for sustainable development in the chemical industry. This achievement set a standard for future innovations, encouraging companies to pursue eco-friendly solutions in product development.
