This PA Essentials self-sticking high tack mount board features pressure sensitive, acrylic adhesive on one side of a solid bleached sulphite board. The surface is extremely smooth, virtually eliminating the orange peel look normally associated with poor quality substrates. Pressure sensitive adhesive is specially formulated for the photographic industry and will not interact with photographic emulsions or digital prints. This board also works great for keeping art papers and stitchery fabrics smooth and wrinkle-free for professional looking mounting and framing. Details:Solid bleached white16" x 20"24 pt.
