摘要 |
<p>This invention relates to a new process for the production of aqueous dispersions or solutions of polyurethane-polyureas by reacting NCO-prepolymers which have been hydrophilically modified and/or which contain external emulsifiers with organic polyamines and/or hydrazines in the aqueous phase, the above-mentioned chain extenders - in the form of their solid adducts with inorganic or organic acids - being mixed with the NCO-prepolymers to form a suspension before production of the dispersion or solution. The invention also relates to the dispersions or solutions obtainable by this process and to their use for the production of coatings or bonds.</p> |
