This revolutionary time- and work-saving product is ultra-smooth, warp-resistant and has a unique heat-activated adhesive coating that makes mounting faster and easier. The foam core is pre-coated on one side with heat-activated adhesive developed by Seal. It is safe to use because it requires a low 180ºF operating temperature in a dry mount press. The heat and pressure activate the adhesive coating, forming a smooth, permanent bond. There's no measuring, cutting or tacking because no dry mounting tissue is needed. Ideal for mounting a wide range of materials, including posters, smooth paper artwork, photographs, clay-coated papers and a variety of fabrics.
