Environmental, health and safety concerns continue to drive rapid growth for polyols in green coatings applications. This demand has resulted in increased use of more sustainable materials versus traditional fossil petroleum feedstock. Since 2007, Resinate has been pioneering ways to impart critical performance properties while reducing environmental and human health impacts. By using recycled content as an alternative feedstock source, Resinate is able to extend the life cycle of finite resources already mined from the earth in order to create high-value coatings solutions. One key ingredient of -Resinate polyols is recycled polyethylene terephthalate (PET), which is commonly harvested from plastic water bottles otherwise destined for landfills. This article explores the properties and benefits of Resinate’s proprietary recycled-content polyols in experimental polyurethane dispersion (PUD) coatings applications.
Resinate polyols are made with recycled PET, which imparts excellent performance properties while providing a distinct sustainability advantage. To make the polyol versatile such that it can be employed for a range of coating, adhesive, sealant and elastomer (CASE) applications, several proprietary recycled and renewable components are incorporated into the polyol backbone. These components, in conjunction with the recycled PET, provide the polyol with the necessary latitude to address a wide array of performance requirements, including hydrolytic stability, excellent chemical and stain resistance, an ideal balance of flexibility and hardness, and adhesion to a wide variety of substrates.
