This Un-Du adhesive remover instantly removes all self-sticking and pressure sensitive stickers, labels, tapes and adhesives without staining or damaging surfaces. Use it to remove commonly used mounting adhesives including ATG tapes, heat activated mounts, fusion, spray mounts and more without leaving behind any residue. Acid-free, it is photo safe, archival and will not damage acid-or lignin-free paper making it ideal for scrapbooking. Un-Du works by neutralizing adhesive temporarily and then quickly evaporating, allowing you to reuse the sticker, tape or label once it dries. The Eco Friendly Formula (UD01004-40) is VOC Compliant, and is the only version available for sale in the state of California. Sale of the non-compliant version in the state of California is illegal and punishable by the state.
