Abstract
Methods of modulating tackiness of a substrate bearing an adhesive. The method includes modulating the tackiness of a layer of adhesive by subjecting the layer of the adhesive to radiant output from a radiation source. At least a portion of the radiant output has a wavelength of less than 200 nanometers.
Claims16
A method of modulating tackiness of a substrate bearing an adhesive, said method comprising:
- providing a substrate comprising a first major surface and a second major surface, wherein a layer of an adhesive is disposed on at least a portion of either or both of the first major surface and the second major surface;
- and
- modulating the tackiness of the layer of adhesive without affecting the bulk adhesive properties of the layer of adhesive by subjecting the layer of the adhesive to radiant output from a radiation source, wherein at least a portion of the radiant output has a wavelength of less than 200 nanometers.
