摘要： A disposable bandage, and a process for manufacturing it, which is prepared from a single sheet or strip of liquid permeable, flexible thermoplastic hydrophilic foam. The process includes coating the entire surface of one side of a foam sheet or strip with a layer of porous pressure sensitive adhesive, positioning wound release material in the area of the sheet or strip intended for wound contact, covering the same side of the laminate with a suitable release liner and heat compressing the laminate except at the locus of the wound release material. The foam bandage so produced includes both a resilient absorbent pad and thin but absorbent adhesive-coated tabs. Optionally, the bandage may have a moisture vapor permeable, moisture impermeable skin thereon, to provide a water- and bacteria-proof protective outer layer for the foam bandage.

摘要： A method of mechanically frothing and casting an aqueous polyurethane dispersion yields a foam which, when rolled, wound or stacked, is self-releasing from the pressure sensitive adhesive layer co-cured therewith. The method includes admixing an aqueous ionic polyurethane dispersion with a stearate stabilizer and an optional aziridine crosslinking agent, frothing and casing the admixture, and co-curing the resultant foam sheet with a pressure sensitive adhesive layer. Before frothing, the polyurethane dispersion contains particles having an average size of less than one micron, and contains between 35 and 70 percent by weight of the polyurethane dispersion, between 13 and 50 percent by weight of a 33 percent by weight dispersion of a stearate salt, and up to 33 percent by weight of polyfunctional aziridine. The foam produced from the frothed admixture provides a substrate with which an uncured pressure sensitive adhesive can firmly co-cure but to which the cured adhesive demonstrates readily removable adhesion. The laminate of the foam with a pressure sensitive adhesive thus provides either a medical dressing, or a general purpose tape for industrial use, which may be stacked or self-wound without release paper.
摘要翻译：机械起泡和浇铸水性聚氨酯分散体的方法产生泡沫，当被卷起，卷绕或层叠时，它们与与其共固化的压敏粘合剂层自发释放。该方法包括将水性离子聚氨酯分散体与硬脂酸酯稳定剂和任选的氮丙啶交联剂混合，起泡并包住混合物，并用压敏粘合剂层共混固化所得泡沫片材。在起泡之前，聚氨酯分散体含有平均粒度小于1微米的颗粒，并且含有35至70重量％的聚氨酯分散体，13至50重量％的33重量％的硬脂酸盐分散体，多达33重量％的多官能氮丙啶。由发泡混合物生产的泡沫提供了一种基底，未固化的压敏粘合剂可以通过该基底牢固地共固化，而固化的粘合剂显示出易于拆除的粘附。泡沫与压敏粘合剂的层压体因此提供医疗敷料或工业用途的通用胶带，其可以堆叠或自动缠绕而没有剥离纸。
