How can MFC replace synthetic binders to enhance your coating formulations?

Understanding MFC and its benefits

Microfibrillated cellulose (MFC) is a natural, renewable material derived from plant fibres. At KCL, our MFC is meticulously crafted from industrial agro sidestreams, specifically sugar beet pulp, a by-product of the sugar industry. The process involves removing lignin and hemicellulose, followed by mechanical fibrillation to produce microfibrillar cellulose. This method is not only energy-efficient but also boasts a low carbon footprint, making it an environmentally friendly alternative to synthetic materials.

MFC offers a range of benefits that make it an attractive option for various applications. Its high surface area and unique fibrillar structure provide excellent mechanical properties, such as increased strength and stiffness. Additionally, MFC is biodegradable and non-toxic, aligning with the growing demand for sustainable materials in various industries, including coatings.

In the realm of coating formulations, MFC can serve as a natural binder, replacing synthetic latexes and other barrier materials. This substitution not only enhances the performance of the coatings but also contributes to sustainability goals by reducing reliance on petrochemical-based products.

The drawbacks of synthetic binders in coatings

Synthetic binders, commonly used in coating formulations, are typically derived from petrochemicals. While they have been the industry standard for many years, they come with several drawbacks. One of the primary concerns is their environmental impact. The production and disposal of synthetic binders contribute to pollution and carbon emissions, which are increasingly scrutinised in today’s eco-conscious world.

Moreover, synthetic binders can pose health risks. Some of these materials release volatile organic compounds (VOCs) during application and curing, which can be harmful to both the environment and human health. Regulatory bodies are continually tightening restrictions on VOC emissions, making it more challenging for manufacturers to comply with these standards.

Another issue is the cost and volatility of raw materials used in synthetic binders. Fluctuations in oil prices can lead to unpredictable costs, affecting the overall economics of coating formulations. These challenges highlight the need for more sustainable and stable alternatives, such as MFC.

How MFC enhances coating formulations

Incorporating MFC into coating formulations offers several advantages over traditional synthetic binders. Firstly, MFC’s natural origin and biodegradability make it a more sustainable choice. By replacing synthetic binders with MFC, manufacturers can significantly reduce the environmental impact of their products, aligning with global sustainability goals.

From a performance perspective, MFC enhances the mechanical properties of coatings. Its high surface area and fibrillar structure improve the strength and stiffness of the final product. This can lead to material savings, as less coating is required to achieve the desired performance characteristics. Additionally, MFC can improve the barrier properties of coatings, providing better protection against moisture and other environmental factors.

Another key benefit is the reduction of VOC emissions. Since MFC is a natural material, it does not release harmful compounds during application or curing. This makes it a safer option for both workers and end-users, and helps manufacturers comply with stringent environmental regulations.

Case studies: Successful implementations of MFC in coatings

Several companies have successfully integrated MFC into their coating formulations, reaping the benefits of this innovative material. One notable example is a leading paint manufacturer that replaced synthetic latex binders with MFC in their interior wall paints. The result was a product with improved mechanical properties and reduced VOC emissions, which was well-received by environmentally conscious consumers.

Another case involves a packaging company that utilised MFC to enhance the barrier properties of their coatings. By incorporating MFC, they were able to create packaging materials that offered superior protection against moisture and oxygen, extending the shelf life of perishable goods. This not only improved the performance of their products but also contributed to sustainability by reducing food waste.

These case studies demonstrate the versatility and effectiveness of MFC in various coating applications. By leveraging the unique properties of MFC, manufacturers can create high-performance, sustainable coatings that meet the demands of today’s market.

In conclusion, MFC presents a compelling alternative to synthetic binders in coating formulations. Its natural origin, superior mechanical properties, and environmental benefits make it an ideal choice for manufacturers looking to enhance their products while reducing their ecological footprint. At KCL, we are committed to supporting the development and implementation of sustainable materials like MFC, helping our customers achieve their goals in an increasingly eco-conscious world.
