Types of Non-Toxic Varnishes
There are several non-toxic varnishes available today, catering to various applications. One notable example is the polyurethane varnish. When formulated without toxic solvents, polyurethane varnish offers a durable and protective finish. Similarly, acrylic varnishes are gaining popularity due to their water-based nature and minimal VOC emissions.
Fine Art and Varnishes
In the realm of fine art, varnishes play a crucial role in preserving and enhancing paintings on wood panels. Traditionally, a spirit varnish was used. These varnishes contain a high concentration of resins and may start to yellow over time. As the years pass, the protective coat may take on the appearance of amber colored glass. However these varnishes have largely been replaced by more modern and non-toxic options. Artists now have access to a variety of plant-based varnishes that allow them to protect their artwork without compromising their health or the environment.
Furniture Making and Wooden Furniture
Furniture makers have long relied on varnishes to add a protective layer to their creations. Yacht varnish is a well-known choice in this domain, offering a glossy finish that is resistant to moisture, heat, and the elements.
