Graphic Gummed Remoistenable
Graphic Gummed can be activated by water that is applied either automatically or semi-automatically by spray, roller or brush or manually using sponge or similar.
Once activated Graphic Gummed has a good initial tack and dries to a strong final bond. It will adhere to a wide variety of common surfaces, such as paper, cardboard and some glass.
Note: Graphic Gummed 83 gsm will not stick to most plastics or certain metals, for example aluminum. Any assessment should allow the bond to dry fully before testing.
Graphic Gummed may not be suitable for applications which rely on wet tack strength.
Composition: Solvent based adhesive Activated by: water, moisture
Food contact: indirect
Graphic Gummed products can be recycled with paper based packaging or alternatively removed from any packaging by soaking in warm water, some additional abrasion may be required.
Printing on gummed side
Graphic Gummed can be printed on the gummed side using waterless inks bearing in mind that the adhesive is moisture activated. Print should be line or half tones to ensure adhesion is maintained as solid print can neutralize gumming by inhibiting moisture penetration to the adhesive. Alternatively an unprinted border can be left around areas of heavy coverage.
A test print is recommended to ensure complete satisfaction.
