Fixing bandage remarkably decreased in foaming performance

Abstract

PURPOSE: To prevent foaming of a fixing bandage by using a polyisocyanate agent contained in a flexible support material, which comprises a polyisocyanate, a catalyst, adjuvant and an additive. CONSTITUTION: A fixed bandage contains a polyisocyanate in a flexible support material. The polyisocyanate agent comprises an organic polyisocyanate, a catalyst, an adjuvant and an additive. The adjuvant and additive are octamethylcyclotetrasiloxane compounds expressed by formula (I). In the formula (I), R indicates methyl, ethyl, or propyl, and 1≤n≤4. A support material is a natural or synthetic resin-made solid or porous film or an air permeable flexible sheet using foam or fiber as a base material, and the organic polyisocyanate is hexamethylene diisocyanate, 1-isocyanato-3,3,5-trimethyl-5- isocyanatomethylcyclohexane or the like, and the catalyst is an amine catalyst, bismorholinodiethyl ether, a tin catalyst, or etc. COPYRIGHT: (C)1991,JPO
