Mountac Crystal Clear is an optically clear double-sided self-adhesive lamination film which carries a smooth water-based adhesive. Ideal for graphic and photographic face-mount applications where the adhesive layer is required to be invisible. Mountac Crystal Clear is easy to process, provides excellent adhesion to most synthetic materials such as acrylic, PET and PETG as well as glass, metals and timber. Well-suited to long-term internal face-mounting applications often required for galleries, museums and photography, Mountac Crystal Clear is pH neutral meaning it will not materially degrade the printed image over time. Suitable for both internal or external use, we recommend application with a laminator to ensure even tension and pressure.
