New materials must be competitive and provide enhanced product specifications while also delivering sustainability advantages. Many modern materials derived from bio-succinic acid can outperform petro-based equivalents. With further incentives and industry buy-in, they can provide a significant impact. This is why Reverdia works with brand owners and manufacturers towards truly sustainable products. It will keep building on its partnerships to co-develop innovative high-performance solutions throughout the value chain. Brand owners, original equipment manufacturers and chemical companies are becoming increasingly aware of Biosuccinium’s potential to unlock and mainstream sustainable products. Innovative biomaterials Reverdia has been enabling innovative biobased materials since 2010. A joint venture between Royal DSM, the Dutch global Life Sciences and Materials Sciences company and Roquette Frères, the French global starch and starchderivatives company, Reverdia was created to produce and commercialise bio-succinic acid, marketed under the brand name Biosuccinium. Having opened the world’s first dedicated, commercialscale biorefinery for the production of renewable succinic acid in 2012, Reverdia supplies worldwide. Its production plant in Italy continues to use a patented fermentation technology with a best-in-class environmental footprint. Biosuccinium is a biobased alternative to traditional diacids used in the production of plastics and other materials. Thanks to its biobased content and Reverdia’s game-changing technology, bio-succinic acid has a carbon footprint which is half that of petro-based succinic acid and up to 90% lower than adipic acid. www.reverdia.com SEEING POLYMERS WITH DIFFERENT EYES...

New biobased lactide polyester polyols By: Bill Coggio Application and Technology Development Manager Performance Chemicals Division NatureWorks, Minnetonka, USA NatureWorks Introduces new Vercet biobased lactide polyester polyols as reactive intermediates for urethane adhesives and coatings NatureWorks (Minnetonka, Minnesota, USA), known for its broad portfolio of renewably-sourced PLA polymers under the Ingeo brand, recently formed a Performance Chemicals Division to supply lactides, polyols, binder resins, and chemical intermediates to companies that manufacture coatings, adhesives, sealants, elastomers, toners, and fine chemicals products. Vercet is the brand name of the company’s new tunable platform of lactide-based chemistries. Vercet polyols are customizable and provide excellent hardness, solvent resistance, and low color in polyurethanes. Alkyd resins for coatings made using Vercet lactides can significantly reduce resin viscosity enabling low volatile organic compound (VOC) formulations for solvent-borne alkyd coatings for wood and metal. Furthermore, these alkyd coatings exhibit excellent adhesion and show improved abrasion and impact resistance. Solvent-borne coatings and hot melt adhesives utilizing Vercet intermediate resins have a tunable work life and viscosity range with excellent adhesion to metal and plastics. High bio-content reactive intermediates for polyurethane adhesives and coatings Vercet polyols are easily customized to control key properties that impact performance in polyurethanes. Controlled Vercet product properties include hydroxyl functionality, viscosity, glass transition temperature (Tg), compatibility, and solubility. Vercet polyols are easily converted into urethane thermoplastics via a direct reaction with an isocyanate and chain extender, which means Fig 2: Film coated with Vercet-based urethane coating shows high transparency and low haze these new chemistries will be easily substituted for non-biobased intermediates. They can also be made into isocyanate prepolymers to facilitate formulation flexibility for use in 1K and 2K reactive thermoset urethane systems. In reactive hot melt adhesives, Vercet polyols offer excellent adhesion and are tuned to improve green strength shortening component assembly in applications involving wood or plastic products. Vercet polyurethane systems for both coatings and adhesives exhibit superior oil resistance, modulus, adhesion, and gloss compared to a non-biobased control polyester. Vercet polyurethane coatings on metal and plastic demonstrated excellent adhesion even when used with no adhesion promoter and thus offer formulators the potential to simplify formulations and reduce system costs. Since NatureWorks uses biobased feedstocks to produce the Vercet lactides, polyols, and resins the company does not have the price volatility and supply chain pinch points of traditional coating and adhesive components. www.vercet.natureworksllc.com Fig 1: Vercet lactide-based polyurethanes show notable resistance to hydrocarbon oil, vegetable oil, and hexane, a common non-polar organic solvent. 10% 8% 6% 4% 2% 10 DAY WT% SOLVENT PICK-UP 0% -2% IRM 903 OIL CANOLA OIL N-HEXANE WATER CONTROL 10.00% 4.50% 1.50% 0.60% P2040X -0.20% 0.20% 0.60% 0.90% P2140X 0.10% 0.00% 0.10% 1.00% Wt% data collected 68˚C Table 1: Urethane coatings made with Vercet lactide polyols show excellent hardness and adhesion.
