  • Publication number: 20130299074
    Abstract: The invention relates to a method for cross-linking a cross-linkable adhesive composition without solvent on a film, comprising driving and/or guiding said film in a climatic chamber, by a Caroll-type drive or guide. The invention also relates to a climatic chamber comprising a Caroll-type drive or guide. The invention also relates to a process for manufacturing a self-adhesive article comprising at least a substrate and an adhesive layer, said process comprising the steps of: a) conditioning an adhesive composition at a temperature of between 20 and 160° C.; b) coating the adhesive composition b1) onto at least a part of the substrate or b2) onto a non-sticking support; submitting the article obtained at step b) to a controlled atmosphere. The invention also relates to self-adhesive articles having high coating weights and to processes for bonding them.

  • Publication number: 20090291298
    Abstract: 1) Multilayer film comprising 2 thin layers joined by a layer, having a thickness of less than 10 ?m, of an adhesive composition comprising: from 30 to 70% of a blend of styrene block copolymers consisting of 5 to 75% of a triblock copolymer chosen from the group comprising SIS, SIBS, SBS, SEBS and SEPS; and 25 to 95% of a diblock copolymer chosen from the group comprising SI, SBI, SIB, SB, SEB, SEP, the overall content of styrene units of said blend being between 10 and 40%; and from 30 to 70% of one or more tackifying resins. 2) Method of preparing said film comprising a step of coating a first thin layer of material with the adhesive composition, in which said composition, rendered flowable by heating at an appropriate temperature, is extruded by a coating device without contact with said thin layer, in the form of a substantially continuous layer, which is then brought into contact with the surface of said thin layer.
