MULTI-PART POLYURETHANE COMPOSITIONS, ARTICLES THEREOF, AND METHOD OF MAKING

摘要

A multi-part polyurethane composition is composed of a first part comprising a polyurethane prepolymer composition and a second part comprising a polyol having a hydroxyl functionality of 4 to 6, and a desiccant. The composition further comprises a plasticizer, wherein the plasticizer can be present in any one or more of the parts. A polyurethane is formed by mixing and curing the composition. The composition can be used as an adhesive for separatory devices, in particular for potting hollow fibers.
