摘要:
The invention relates to a process for producing polyurethane foams for wound management wherein a composition containing a polyurethane dispersion and specific coagulants is frothed and dried.
摘要:
The present invention relates to biomedical foam articles for the wound sector which are formed by spraying a polymeric dispersion onto a wound. The polymeric dispersion being sprayed onto a wound surface forms a three-dimensional body which conforms to the spatial shape of the wound and which, as well as covering the wound surface, ensures a complete and accurately fitted packing of the wound in the depth dimension as well as the other dimensions. The biomedical foam articles of the present invention are particularly useful for treating chronic wounds.
摘要:
The invention relates to a process for producing polyurethane wound dressing foams comprising frothing and drying polyurethane foam compositions which comprise anionically hydrophilicized aqueous polyurethane dispersions.
摘要:
The invention relates to novel microporous coatings and to a process for the production of microporous coatings. A composition comprising an aqueous, anionically hydrophilised polyurethane dispersion (I) and a cationic coagulant (II) is foamed and dried to provide the microporous coating.
摘要:
The invention relates to novel microporous coatings based on polyurethane polyurea, and to a process for the production of microporous coatings, in which a composition comprising an aqueous, anionically hydrophilised polyurethane dispersion (I) and a cationic coagulant (II) containing a cationically hydrophilised polyurethane polyurea dispersion is foamed and dried.
摘要:
The invention relates to a process for the preparation of novel aromatized chewing foams for the oral care sector based on polyurethane-polyureas and aromatizing compositions
摘要:
The present invention relates to a new aqueous binder system for nail varnishes, based on nitrocellulose-containing polyurethanepolyurea dispersions.
摘要:
The present invention relates to new water-dilutable or water-soluble blocked polyisocyanates which allow the preparation of bakeable one-component (1K) polyurethane coating materials which exhibit rapid initial physical drying, exhibit reduced thermal yellowing and lead to haze-free coatings, to a process for preparing them, and to their use.
摘要:
The present invention relates to dispersions of nanoureas comprising biologically active compounds, a process for their preparation, and their use.
