Bio-based coatings

Bio-based paints are coating materials whose binders, solvents or additives come entirely or partially from renewable raw materials. The aim is to reduce the proportion of fossil raw materials and improve the ecological balance of coating processes. Vegetable oils, natural resins, cellulose, starch or lignin are the main raw materials used. These materials can be chemically modified and thus integrated into modern coating systems.

The development of bio-based coatings is being driven by growing demands for sustainability and climate protection. In addition to a reduced carbon footprint, they also offer advantages in terms of independence from fossil raw material markets. However, they face technological challenges: Consistency, processability and pricing must be able to compete with conventional products. Research projects and collaborations between the chemical industry, paint manufacturers and users are driving innovation.

Bio-based coatings are used in areas such as furniture and interior design, packaging, construction and the automotive industry. Depending on the system, water-based formulations, powder coatings or UV-curing systems based on biogenic raw materials can be realized. The bio-based nature of a coating is usually stated as a percentage and refers to the proportion of organic carbon compounds from renewable sources. In the long term, bio-based coatings are considered a key technology for sustainable surface technology that combines ecological requirements with high performance standards.
