PROCESS FOR THE PRODUCTION OF POLYURETHANE-UREA DISPERSIONS

摘要

The present invention provides a process for the production of non-ionically hydrophilised aqueous polyurethane dispersions which have a broad particle size distribution combined with a relatively large particle size, are readily redispersible and when used to produce polymer films lead to polymer films having a low degree of gloss. The present invention also provides the use of the dispersions produced by the process according to the invention in coatings.
