Evonik bets on bio-based specialty methacrylates with VISIOMER Terra HEMA-P100

Evonik Industries AG has introduced VISIOMER Terra HEMA-P100, a bio-based hydroxyethyl methacrylate, as part of its VISIOMER Terra portfolio. This product replaces a portion of fossil raw materials with plant-derived feedstocks, offering a sustainable alternative for coatings and adhesives manufacturers. Terra HEMA-P100 maintains the performance of conventional methacrylates while reducing the carbon footprint, making it a valuable option for polymer chemists seeking reactive hydroxyl functionality in various systems.

The VISIOMER Terra line provides comparable reactivity and mechanical properties to fossil-based methacrylates, with a bio-based carbon content that supports sustainability certifications and ESG reporting. This allows manufacturers to reformulate existing systems by incorporating Terra HEMA-P100, thereby reducing the fossil carbon share in their products. Lifecycle assessments indicate a smaller cradle-to-gate footprint, aligning with Evonik's sustainability strategy.

Evonik emphasizes the use of Terra HEMA-P grades in industrial coatings, adhesives, sealants, and composites. The hydroxyl functionality of Terra HEMA-P100 facilitates crosslinking and enhances adhesion, making it suitable for applications such as high-solids protective coatings, UV-curable clear coats, and flexible adhesive layers. Despite being a specialty monomer, its properties significantly influence the final product's characteristics, including gloss, hardness, and chemical resistance.

In the US, coatings formulators might encounter Terra HEMA-P100 at Evonik's technical centers, where it is presented as part of a broader sustainability offering. The product enables compliance with customer sustainability scorecards without necessitating a complete redesign of resin architectures. This is particularly beneficial for mid-size producers with limited R&D resources.

The bio-based content of the VISIOMER Terra portfolio is quantified using internationally recognized standards, such as ASTM or ISO. Terra HEMA-P100's documentation includes technical data sheets and safety information detailing both performance and sustainability aspects. This supports downstream manufacturers in claiming partial fossil resource replacement, contributing to Scope 3 emissions accounting and eco-labeling.

From a formulation perspective, Terra HEMA-P100 behaves like a reactive monomer with hydroxyl functionality, requiring standard methacrylate handling precautions. Evonik's technical documentation provides guidance on use levels, reactivity profiles, and compatibility with other monomers. In coatings, it enhances adhesion and flexibility, while in adhesives, it enables crosslinking with isocyanates or melamine resins.

Evonik markets the VISIOMER portfolio globally, with production and technical centers in Europe and regional support for North America. Pricing for Terra HEMA-P100 is typically negotiated based on volume and feedstock costs. The product is part of Evonik's Smart Materials segment, contributing to the company's strategy of offering tailored solutions for higher returns in the coatings, construction, and adhesives markets.
