Purac has launched its new range of Puralact, special grade lactides. Puralact offer several benefits for enhancement of coating resins. 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% biobased, resulting in coating resins with a lower carbon footprint.
Puralact has been tested in several coating formulations. 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, according to the company. Produced on a large industrial scale by Purac, the new range is commercially available worldwide.
