Polyurethane Finish - Toxic or Toxin Free?

10/23/17

Products crafted from wood, especially furniture, will need a protective coating to prevent the aging, staining, and discoloration that would otherwise occur. Wood is a tough, durable, and versatile building material, but it is also porous which means that it can easily be discolored, stained, and even damaged over time without proper protection.

Of the many finishing products, most notably shellac, lacquer, and varnish, polyurethane has become quite popular thanks to its effectiveness and low price. It’s now quite common to see polyurethane finishes on a wide variety of furnishings crafted from wood.

What is Polyurethane?
It is an oil-based product, something like liquid plastic that hardens when it dries. Because it is easily available, inexpensive, and highly resilient, and it makes the perfect finishing product for wood. There are two types of polyurethane finishes, oil-based and water-based. Plus, you can find several varieties that run from glossy to satin which helps highlight the beauty of the wood.

Oil-based polyurethanes are the more traditional version that provide proper protection for the wood. However, it carries a strong odor, adds a slight coloring to the wood that you may not want, and takes a long time to dry. Because of these factors, most oil-based polyurethane products are well suited to outdoor furnishings because of its resilience. 

Water-based polyurethane has the advantage of being low in toxins and does not carry the strong odor of the oil-based varieties. It applies in a clear form that does not add any color to the wood and it will dry quickly which is why it’s a popular choice. It’s well designed for desks, side tables, picture frames, and even bookcases and wooden floors. However, the water-based form does not hold up well when exposed to chemicals or heat. This means that it should not be used on furniture or furnishings that are exposed to sunlight or high temperatures.

However, there is a danger when using either type of polyurethane finish products, especially the oil-based versions for items that you plan on keeping inside the home.

The Dangers of Polyurethane

Polyurethane contains volatile organic compounds (VOCs) that present a health danger to anyone exposed to this toxin. When still in its liquid form, toxins like isocyanates in the finish will start to evaporate when exposed to the air. That is why it is recommended that protective masks should be worn and the work done in a well-ventilated area.

Once the finish dries, the remaining toxins are locked inside. However, they are still being released at a slower rate over time. While water-based polyurethane finish is relatively low in toxins, the problem is that when they are released over a long period, they can build up in the indoor air of the home and present potential health issues for people and pets who live inside the business or residence.
For those who need more information about non toxic alternatives to polyurethane finish, you can contact the experts at Hybrid Coating Technology. They can provide you with the guidance needed so you can make the best-informed decision about which products may work best for your needs.
