Purac launches special grade lactides for coatings

According to the company, the main advantage of incorporating Puralact is a significantly reduced resin viscosity. This provides the opportunity to formulate coatings with higher solid content, lower VOC and improved ‘ease-of-use'. Purac's new Puralact is 100 % bio-based, resulting in coating resins with a lower carbon footprint. Puralact is thoroughly tested in several coating formulations, says the company. Depending on the type of coating and its specific use, the new products enhance coating performance by improving properties, such as stiffness, adhesion, impact resistance, balance between hardness and flexibility, chemical resistance, gloss and gloss retention, and tuning of drying time. Produced on a large industrial scale by Purac, the new range is commercially available worldwide. Produced from bio-based lactic acid, the new product is said to have a significantly lower CO2 footprint than the fossil-based building blocks most frequently used to produce coating resins. Replacing these traditional products with Puralact reduces the carbon footprint of both coating resin and final coating.
