Teknos develops more sustainable coatings for paper and paperboard
As Teknos announces, the companies are creating new moisture and grease resistant surfaces for food packages and disposable tableware made with so called barrier coatings, replacing problematic plastic films. The new barrier coatings will be made for easy recyclability at first, then contain bio-based materials, and ultimately be biodegradable.
“Currently the greatest challenges in developing bio-based coatings are finding uniform raw materials that fit the supply chain, and the availability of raw materials,” says Teknos’ Commercial Manager Tuomas Aspiala.
Lignin as bio-based raw material for coatings
One possible bio-based raw material for coatings that is being researched is lignin. It is renewable and abundant and is a byproduct of various industries such as the pulp industry. Lignin that cannot be reused is currently burned for generating energy.
As the company tells, circular economy and resource efficiency are at the core of Teknos’ operations and R&D. The carbon footprint associated with raw materials purchased plays a major share of a coatings company’s total carbon footprint. One method of reducing the impact is reducing the use of virgin raw materials by using more recycled materials in manufacturing, for instance industrial side streams. Waste created in Teknos’ own manufacturing is recycled as much as possible and used again as raw materials.
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.
