Water based polyurethane is a type of polymer that is used for a variety of applications, including coatings for wood and concrete, adhesives, and sealants. Its durability and resistance to water making it a popular choice for protecting surfaces from moisture damage.

What is Water based polyurethane

The key difference between water-based polyurethane and other types of polyurethane is the type of solvent used in its production. Traditional polyurethane is made using volatile organic compounds (VOCs) as a solvent, which can be harmful to both humans and the environment. In contrast, water-based polyurethane uses water as the solvent, which is much less harmful and easier to clean up.

Water based polyurethane is made by mixing a polyol (a type of alcohol) with a diisocyanate (a type of organic compound). When these two chemicals are mixed together, they react to form a polymer chain, which is then dissolved in water. This creates a liquid that can be applied to a variety of surfaces to create a protective coating.

Water Based Polyurethane Avantages

One of the main benefits of using water-based polyurethane is that it is much less harmful to the environment than traditional polyurethane. Because it uses water as a solvent, it does not release VOCs into the air, which can cause air pollution. In addition, it is easier to clean up than traditional polyurethane. So it can make it a safer choice for use in residential and commercial settings.

Another benefit is that it is less likely to yellow over time than traditional polyurethane. This is because it does not contain the same chemicals that can cause yellowing, such as isocyanates and toluene. As a result, water-based polyurethane maintains its color and clarity for a longer period of time. This will make it a popular choice for protecting surfaces that will be on display, such as furniture and floors.

Water-based polyurethane is also known for its durability and resistance to water. It forms a strong and flexible film on the surface that it is applied to. It makes it resistant to scratches, scuff marks, and other types of damage. In addition, it is highly water-resistant, which makes it an effective choice for protecting surfaces from moisture damage.

Despite these benefits, there are a few drawbacks to using water-based polyurethane. One of the main disadvantages is that it is not as durable as traditional polyurethane. Because it is less viscous, it can be more susceptible to wear and tear, which can cause it to break down over time. In addition, it is not as effective at protecting surfaces from UV light and other forms of radiation, which can cause it to fade or become discolored.
