Durable wood coatings that retain the natural look

Wood is one of the most beloved materials we use in our homes, both indoor and outdoor. As wood is natural material, it requires coating and treatment to preserve its qualities and looks against the elements, daily wear and tear and natural decay. Water-based resins solutions from Stahl offer that protection with exceptional properties, versatile application and numerous production benefits.

Outdoor wood finish that is strong and durable

From simple fencing to iconic wooden-landmarks and design hotels, outdoor wood needs protection against rain, sun and freezing temperatures. Stahl provides polymeric technologies that are highly durable and resistant. These resins react with the wood, while retaining its flexibility, natural look, warmth and pleasant touch. They protect wood against UV exposure, daily use and handling or damaging. Wood coating resins for outdoor use offer both high gloss and (semi) matte finishes and can also be pigmented to offer color options.

Retaining the pristine looks of indoor wood

Many of our solutions are free of hazardous effects and solvent-free to ensure a safe home interior environment with fresh air. We modify several of our VOC-free or low-VOC water-based coatings with natural oils instead to offer both longevity and a sustainable option for a lasting interior that is safe and healthy. Our technologies are an easy choice for formulators as they can easily be enhanced through crosslinking with polycarbodiimide crosslinkers that selectively react with carboxylic acid (–COOH) groups in polymer chains. When opting for a 2K coating the chemical resistance against chemicals, stains and water are enhanced and also hardness and scratch resistance. This way, we ensure the pristine quality of natural wood is preserved. Our portfolio contains many APEO- and solvent-free acrylics, urethanes and hybrids to create the right coating, whether it concerns furniture, wooden interior parts or even toys and decoration.

Your partner in Indoor & outdoor wood coatings technology

The wood coatings market has always been a priority for Stahl. Our R&D team uses the best available technologies (core-shell, controlled particle size, self-crosslinking, renewable resources, etc.) to develop new binders. The application team combines and formulates them in order to bring them to their peak performance. Not just in the coating properties, but also in production benefits such as fast-drying, non-sticking and easy sanding properties. Together with the long pot-life, this makes Stahl wood coating resins a value-add for manufacturers, both in production as well as product properties.

Key Benefits of Indoor & outdoor wood coatings
