It is envisaged that the pressure-sensitive adhesive comprises a first layer and a second layer, the first layer being a heat-activatable pressure-sensitive adhesive which has a static glass transition temperature Tg,a or a melting point Tm,a of at least +30° C.; and the second layer being a polyacrylate pressure-sensitive adhesive which has a static glass transition temperature of not more than +15° C.
摘要:
The adhesive tapes (20) for sticking together printing blankets on a metallic retaining bar or metal rail during a printing process. The adhesive tapes are composed of at least one layer (25), a release liner, and of a melt pressure-sensitive adhesive layer (30) that is applied to said release liner layer on one side. Both sides of the release line layer (25) have the same or different release.
