Adhering Two Substrates Using Latent-Reactive Adhesive Films
The invention relates to a method for adhering two substrates, namely a first substrate A and a second substrate B, to each other using a latent-reactive adhesive film with at least one latent-reactive adhesive film layer which has a thermoplastic component with a melting temperature T(melt), where 35° C.≦T(melt)≦90° C., said thermoplastic component containing functional groups that can react to isocyanate, and an isocyanate-containing component that is dispersed into the thermoplastic component in a particulate form and is blocked, microencapsulated, or substantially deactivated in the region of the particle surface. The particles have a start temperature T(start) of 40° C.≦T(start)≦120° C., wherein T(start)≧T(melt). A surface of the first substrate A is brought into contact with a first surface of the latent-reactive adhesive film, and a surface of the second substrate B is brought into contact with the second surface of the latent-reactive adhesive film. The adhesion is caused by heating the latent-reactive adhesive film to a temperature which corresponds to or is higher than at least the start temperature T(start). The invention is characterized in that at least the surface of the first substrate A which is brought into contact with the latent-reactive adhesive film is treated with a primer before the first substrate A is brought into contact with the latent-reactive adhesive film, and/or at least the first surface of the latent-reactive adhesive film which is brought into contact with the first substrate A is treated with a primer before the first substrate A is brought into contact with the latent-reactive adhesive film.
Adhesive tape for encapsulating electronic constructions
The aim is to provide an adhesive tape that effectively protects an electronic construction from permeants, especially water, and that at the same time has good gap-filling qualities. To solve this problem an adhesive tape is proposed that has in the following order:—a carrier layer without barrier effect at least towards water and with a WVTR of at least 1 g/(m.sup.2*d) (38° C., 90% relative humidity, 50 μm layer thickness); —a layer comprising at least one getter material capable of sorbing at least water; —a water barrier ply; and—a layer of pressure-sensitive adhesive, where the carrier layer bears an outward-facing release layer and/or the layer of pressure-sensitive adhesive is lined with a release liner which has a release layer lying on the layer of pressure-sensitive adhesive.
Green ceramic tapes and method for their fabrication
“Green”, ceramic tapes intended as building blocks for making complex, fully ceramic components and devices for electronic-, lab-on-chip-, and sensing applications, the manufacture of which comprises in sequence: I. mixing of a ceramic “green” paste, II. homogenisation of a ceramic “green” paste, III. dimensioning and optionally structuring the ceramic “green” paste, IV. drying of the dimensioned and structured ceramic paste, in which: step iii) is performed in a combination of an extruder and a calender, the extruder being provided with a circular extrusion die, splitting and unfolding the extruded tube to a flat, continuous tape strip, using methylcellulose or derivatives thereof as binder, and, an additional step chosen among cutting and punching the thus dimensioned and optionally structured “green” paste, thereby making thick, “green” tapes. A method for its manufacture is also contemplated.
LAMINATE AND LABEL
Provided is a laminate and label for laser printing which are capable of preventing or reducing the occurrence of failure in printing by laser light irradiation.
