ColorMount is a porous tissue coated on both sides with a low temperature adhesive that bonds while hot. Permanent bonding occurs at 185°F. Specially formulated for permanent, low-temperature dry-mounting or RC photographs. It’s also an excellent general-purpose adhesive for most other mounting applications, including slick poster materials, blueprints, lithographs and other smooth artwork. Works well with almost all mounting substrates - cardboard, foam boards, Masonite, aluminum and Plexiglas.
