Abstract
In the case of a liner for the protection of adhesives, the protective effect is to be enhanced in respect of permeates originating from the environment and also permeates included during winding or stacking and other processing steps. This enhancement is accomplished through provision of a liner which comprises at least one adhesive release layer and at least one layer of a getter material capable of sorbing at least one permeable substance.
Claims9
A release liner for the protection of adhesive, the release liner comprising a first layer contacting a second layer, wherein the first layer of the release liner is an adhesive release layer and the second layer of the release liner is a layer of a getter material capable of sorbing at least one permeable substance, wherein the getter material is selected from the group consisting of calcium oxide, boron trioxide, sodium sulfate, potassium carbonate, copper sulfate, magnesium perchlorate, magnesium sulfate, zeolites and mixtures thereof.
A method comprising:
- providing an adhesive tape that is at least partially covered on at least one side with a release liner comprising (i) at least one adhesive release layer and (ii) at least one layer of a getter material capable of sorbing at least one permeable substance, wherein the getter material is selected from the group consisting of calcium oxide, boron trioxide, sodium sulfate, potassium carbonate, copper sulfate, magnesium perchlorate, magnesium sulfate, zeolites and mixtures thereof;
- and
- encapsulating optoelectronic arrangements with the adhesive tape.
