| titleOfInvention |
Storage-stable polyurethane potting compound for embedding of hollow fibres in the production of filter elements |
| abstract |
Polyurethane encapsulating compounds for the embedding of hollow fibers of filter elements are provided. These are obtainable by mixing a polyol component (A) and an isocyanate component (B) to give a reaction mixture and reacting the mixture to completion to give the polyurethane encapsulating compound, wherein the polyol component (A) comprises (a1) at least one fatty-acid-based polyol, (a2) at least one amine compound having at least one tertiary nitrogen atom and at least one isocyanate-reactive hydrogen atom and (a3) at least one metal compound that functions as a polyurethane catalyst, wherein the polyurethane catalyst (a3) does not comprise any tin, lead and/or mercury and the isocyanate component (B) comprises at least one aromatic isocyanate having at least two isocyanate groups. Further provided is a method for producing filter elements using the polyurethane encapsulating compounds and the use of the polyurethane encapsulating compounds for the embedding of hollow fibers. |
