Production of laminated thin plaster, used as wound dressing, involves coating intermediate carrier with polyurethane and release layer with adhesive mass, lamination and reduction to final thickness by passing through roll nip
Production of laminated thin plaster with a polyurethane-based substrate comprises (a) applying polyurethane layer(s) (I) to an intermediate carrier (II); (b) applying an adhesive mass (III) to a release layer (IV); (c) laminating the unhardened (I) on (II) and (III) on (IV), especially with a docto...

Abstract | Production of laminated thin plaster with a polyurethane-based substrate comprises (a) applying polyurethane layer(s) (I) to an intermediate carrier (II); (b) applying an adhesive mass (III) to a release layer (IV); (c) laminating the unhardened (I) on (II) and (III) on (IV), especially with a doctor; and (d) passing the laminate through a roll nip, in which (I) and (III) are rolled out to the final thickness.
Verfahren zur Herstellung von mehrschichtigen dünnen Pflastern mit einem Trägermaterial auf Polyurethanbasis, wobei DOLLAR A a) zumindest eine Schicht eines Polyurethans auf einen Zwischenträger aufgebracht wird, DOLLAR A b) auf eine Trennlage eine Klebemasse aufgetragen wird, DOLLAR A c) das nicht ausgehärtete Polyurethan auf dem Zwischenträger und die Klebemasse auf der Trennlage insbesondere von einem Rakel zusammenkaschiert werden, DOLLAR A d) nach dem Rakel das Laminat in einen Walzenspalt geführt wird, in dem das Polyurethan sowie die Klebemasse auf die endgültige Dicke ausgewalzt werden. |
