Faced with the environmental challenges confronting the paint industry, bio-based paints are emerging as innovative solutions combining performance, durability, and environmental respect. With a growing demand for products that align with carbon footprint reduction and circular economy objectives, bio-based paints offer a major competitive advantage.
But how do you guarantee their quality and compliance with environmental standards ? Does the “Bio-based Product” label a real strategic lever for industry professionals, or simply a marketing asset?
In this article, we explore the challenges of bio-based paints, the regulations to comply with, the analyses required to obtain the label, and their environmental impact. Discover how these solutions are transforming industrial practices, and how analytical laboratories contribute to supporting companies towards sustainable practices.
Understanding biosourced paint and its label
The development of bio-based paints is gradually becoming established in the industry. Their use, coupled with obtaining the "Bio-based Product" label, indeed addresses environmental and regulatory issues of paramount importance for industry professionals.
Definition and challenges of bio-based paints
Bio-based paints differ from conventional paints due to their composition derived from renewable raw materials, such as vegetable oils or agricultural residues. Unlike conventional paints, they limit the use of petroleum derivatives and thus offer a more environmentally friendly alternative.
For industrialists, they represent an opportunity to integrate ecological materials into their compositions while meeting growing consumer expectations. Their production is part of a bioeconomy strategy, reinforced by regulatory incentives such as the Energy Transition for Green Growth Law in France.
However, bio-based paints do not just meet environmental criteria: they also offer robust technical solutions. They are thus integrated into demanding specifications, particularly for the automotive, construction, and aeronautics sectors, where the performance and resistance of coatings are paramount.
For R&D services seeking innovation, understanding the specificities of these paints becomes a strategic lever allowing them to stand out.
The key role of the "Biosourced Product" label
The "Bio-based Product" label certifies the percentage of bio-based materials in paints, ensuring essential transparency for industry stakeholders.Obtaining the "Bio-based Product" label relies on a precise regulatory framework that guarantees the compliance of industrial paints.
European and international standards, such as NF EN 16640, require manufacturers to demonstrate a minimum percentage of bio-based material, as defined in their formulation. This percentage is calculated using advanced characterization methods, notably carbon-14 dating, which allows for the differentiation of bio-based compounds from fossil materials.
According to the label's public framework, bio-based paints must incorporate at least 20% renewable materials to obtain certification, a figure that can vary depending on product categories.
Industrial paint analyses concerning chemical composition are mainly carried out by laboratories specialized in the bio-based industry such as CIRAM. Characterization methods, a guarantee of reliability, reassure industrial partners and end customers, while facilitating the integration of these paints into projects respecting strict environmental standards.
This proactive approach helps avoid non-compliance, reduces regulatory risks and opens up opportunities in markets that value eco-responsible solutions, such as the automotive and construction industries.
Analysis and control of bio-based industrial paints
The precise determination of the bio-based content percentage is a mandatory step to obtain the label. Laboratories specialized in the bio-based industry, such as CIRAM, play a key role by carrying out detailed chemical analyses.
Two main routes are used:
- Radiocarbon dating, in accordance with standard EN 16640,
- The material balance approach (EN 16785-2).
Radiocarbon analysis guarantees complete transparency on the bio-based composition of paints. This test includes the quantification of components of plant or renewable origin.
Other controls ensure that paints meet expected performance in demanding environments. For industry professionals, collaborating with experts in radiocarbon analysis of industrial paints guarantees total transparency and optimization of formulations. This not only secures the certification process but also strengthens competitiveness in a market where green innovation has become an essential differentiating criterion.
Performance, durability and environmental impact of bio-based paints
Beyond their composition, bio-based paints must prove their performance and their positive environmental impact to establish themselves as credible alternatives to synthetic paints for industrial users.
Performance and durability testing of bio-based industrial paints
Bio-based paints cannot simply be environmentally friendly: they must also meet the high standards of industrial applications. These include rigorous tests to evaluate their mechanical resistance, their durability under extreme conditions (heat, humidity, friction), and their adhesion on various substrates.
Current tests no longer focus solely on mechanical or chemical resistance, but now include criteria related to the interaction of paints with the materials on which they are applied. For example, bio-based formulations improve adhesion on complex surfaces such as composites or light alloys, commonly used in aeronautics and automotive industries.
In parallel, the performance tests now include analyses of industrial paints concerning their long-term stability under extreme conditions, as well as the compatibility of paints with bio-based multi-layer systems.
These new approaches ensure that paints incorporating bio-based products do not compromise the durability or the requirements of the most demanding industrial sectors. By collaborating with specialized analysis laboratories for bio-based paints such as CIRAM, manufacturers can ensure that their products' composition meets these new standards while offering innovative and sustainable solutions.
Environmental impact of industrial paints and bio-based coatings
The environmental impact of biobased paints can be seen primarily in their reduced carbon footprint and overall life cycle. By integrating renewable raw materials and minimizing VOC (volatile organic compound) emissions, paints incorporating biobased products contribute to reducing negative impacts on air quality and climate.
According to the "Bio-based Product" label, some products display up to 60% biomass of French origin, strengthening their local footprint and their contribution to the circular economy. For manufacturers, this is a strong argument in a sustainable development strategy, limiting volatile organic compounds for controlled markets such as aviation, construction, or automotive.
Life Cycle Assessment (LCA) of bio-based paints finally makes it possible to evaluate their overall impact, from the production of raw materials to their end of life. This approach guarantees that paints meet environmental criteria at each stage of their use. Increasing the share of paints produced from bio-based products not only allows manufacturers to reduce their carbon footprint but also to achieve their internal and external CSR objectives.
Bio-based paints represent a major breakthrough for industry professionals seeking new processes. Their integration relies on a thorough understanding of standards, precise composition analysis, and rigorous testing to ensure their durability and low environmental impact.
The "Bio-based Product" label then plays a central role, certifying the transparency and quality of products, thus offering a competitive advantage in demanding markets. In this context, laboratories such as CIRAM, specializing in the analysis of bio-based paints, are essential partners for supporting manufacturers in their certification, innovation, and product formulation optimization efforts.
