Abstract: The invention relates to a production method for a foam wound dressing with an outer germ barrier, in particular a film layer, and to a wound dressing obtained by such a method. In the method according to the invention, the germ barrier is generated by means of extrusion directly on the foam support. This results in a more reliable union between foam layer and germ barrier, without thereby compromising the absorbency of the foam in respect of wound exudate. The proposed method is simple and inexpensive and is able to satisfy all the requirements of the medical sector (e.g. freedom from solvents).

Abstract: The invention relates to a production process for a foam wound dressing having an external germ barrier, more particularly a film layer, and also to a wound dressing thus obtained, having, where appropriate, a pressure-sensitive adhesive layer. In the process according to the invention the germ barrier is produced by means of extrusion directly on the foam base. This results in a more reliable bond between foam layer and germ barrier, without detriment to the absorptiveness of the foam for wound exudate. The process presented is simple and cost-effective, and all of the requirements from the medical sector (e.g. absence of solvent) can be met.

Abstract: The invention relates to a hot-melt composition, especially for using as an absorbent medical or cosmetic article, preferably as a wound dressing, and containing (a) a chemically cross-linked polymer matrix, and (b) hydrocolloids which are embedded in the chemically cross-linked polymer matrix. The inventive composition can be obtained by processing a melt in a hot melt method, said melt having a melting viscosity of less than 100 Pa*s, preferably less than 75 Pa*s, and especially preferably less than 50 Pa*s, at a processing temperature of less than 150° C., preferably less than 140° C., and especially preferably less than 130° C.

Abstract: The invention relates to a hybrid adhesive comprising a silane resin and an epoxy resin, further comprising (a) at least one nonaromatic tertiary diamine or polyamine, selected in particular from the group consisting of aliphatic amines, cycloaliphatic amines, amidoamines, and mixtures thereof; and (b) at least one silane catalyst which is not an amine compound, being more particularly an organometallic compound, preferably selected from the group consisting of organotin compounds, organozirconate compounds, organotitanate compounds, and mixtures thereof. The hybrid adhesive is suitable for application to vertical surfaces and is of outstanding light transmittance.

Abstract: The inventive composition contains at least one polyacrylate that can be melted and cross-linked using UV light, optional additives and is characterised by an oligomer compound comprising at least one functional group that can be cross-linked using UV, said compound having a viscosity of between 0.1 and 20 Pa·s at 25° C. The invention also relates to the use of the composition as a UV cross-linked hot-melt adhesive and to a method for producing a substrate that is provided with the composition. The composition can be used at a lower temperature than previous conventional hot-melt adhesives.
