First recycled door coated with plant-based resin
DSM’s "Decovery" plant-based resin technology is used for the first time on Weekamp’s new 100% recycled exterior doors concept.
This is a result of a collaboration between PPG Wood Finishes, Weekamp Deuren and DSM to further develop sustainable exterior doors by using recycled wood and plant-based coating.
Currently mainly waterborne paint is used to protect exterior doors. These waterborne paint products are a big improvement compared to previously used solvent-based coatings. However, the binders of these waterborne paints still contain fossil-based raw materials. DSM‘s "Decovery" is a new technology that replaces the fossil-based binder components of a coating for a large part with renewable materials while maintaining the quality and performance.
Developing an acrylic plant-based coating
It is Weekamp Deuren’s goal to work with 100% green or sustainable wood. Weekamp was interested to find a coating solution that would support a more sustainable finishing. DSM believes that collaboration and innovation play a crucial role to create a sustainable world. Weekamp Deuren, PPG Wood Finishes and DSM joined forces to develop an acrylic plant-based coating to protect exterior recycled doors from external elements like sun, wind, rain in a sustainable way.
PPG Wood Finishes effectively used "Decovery" to develop a brushable and sprayable plant-based paint for wooden exterior doors. PPG also uses "Decovery" in its air-cleaning, waterborne ultra-matte wall paints so they were aware of the characteristics of the resin.
Searching for sustainability
As sustainability and circularity are becoming more and more important, and the building & construction industry is continuously searching for the next step in sustainable development, this collaboration shows the value of connecting different parties’ in the value chain and creating awareness on the benefits of more sustainable paint and coating throughout the building & construction industry.

High Solid Binders
High solids are the epitome of high performance and low environmental impact. They are usually the best option where solvent-borne systems would otherwise be the only choice. This book delivers comprehensive knowledge in the field of high solid systems. More especially, it provides an overview of the various classes of binders and ways of transforming them into high solid binders. It lists a broad range of options and approaches for tackling technological and environmental problems. This book addresses the paint and coatings chemists for a better understanding of chemistries and processes involved in film forming hopefully helping in coating design.
