Mounting adhesive sheets are made with a pressure sensitive adhesive that is sticky to the touch, so there is no heat required to make the adhesive stick, making them extremely user friendly and cost effective, as they don't require any investment into machinery. Also called cold adhesive, these mount sheets are made with a high quality, 3 mil acrylic adhesive that work well with mounting boards of many kinds, including standard foam boards, masonite boards and more. It is a pH neutral adhesive that won't yellow and works well for indoor and temporary outdoor prints. Our double sided mounting adhesive sheets let you mount prints and photos to boards with ease by just peeling the liner and applying it to your items. The liners are made of silicone, and are easy to peel off smoothly. Ready to mount prints? Buy pressure sensitive mounting adhesive sheets online today. They are packaged with 25 sheets per box.
