Abstract:
Provide is a skin product, which can be better tailored with respect to controlling the properties of the first and second surfaces. This is obtained by cutting holes in an adhesive matrix with a laser and subsequently filling these holes with a second material. Being able to design the exact location, orientation, distribution and/or size of the second material opens the path for adhesive products where e.g. adhesion, absorption, and permeability are controlled and balanced.
Abstract:
A method of decreasing the penetration depth of radiation provided to an interface, such as a surface, or a predetermined volume in a polyethylene element, where the PE element has a scattering coefficient larger than one tenth of an absorption coefficient thereof so that the radiation not absorbed at the interface or in the volume but transmitted further into the PE element is at least partly reflected toward the interface/volume. The radiation intensity is higher in the volume and the absorption coefficient may be reduced while retaining the total absorption in the volume. This may be used for all known techniques where radiation is desired absorbed, such as in welding, surface preparation, polymer chemistry, the activation of photo activatable substances etc.
