Pressure-sensitive permanent adhesive is designed to mount over old graphics.
Tired of throwing away mounted graphics because you can't mount something else on the board without the old graphic showing through? Drytac has a solution: BlackTac. With high initial tack, this pressure-sensitive permanent adhesive is designed to mount over old graphics, with no show-through.
BlackTac comprises a piece of white polypropylene carrier coated on both sides with a permanent solvent acrylic adhesive; one side is semi-clear, while the other is a deep black light-blocking opaque. The opaque side blocks out the color from the previously mounted image, and the white side provides a bright backing for newly mounted graphics.
BlackTac is available in 51-in. rolls.
