摘要:
The present invention relates to two-component coating systems for the production of polyurea coatings containing A) a sulfonate group-containing polyisocyanate and B) an amino-functional polyaspartate corresponding to formula (I) wherein X represents the n-valent organic group obtained by removing the primary amino groups from an n-valent polyamine, R1, R2 represent the same or different organic groups, which are inert to isocyanate groups under the reaction conditions, and n represents an integer of at least 2. The present invention also relates to coatings obtained from these coating systems.
摘要:
The invention relates to a method for producing hydrophilic, aliphatic polyurethane foams. The invention further relates to special compositions for producing polyurethane foams either using the method according to the invention or using the polyurethane foams obtained from the compositions according to the invention, and to the use of the polyurethane foams as a wound dressing, cosmetic item, or incontinence product.

摘要:
Flavored chewable foams for the oral care sector are produced from a polyurethane-polyurea and a sensorially active substance (e.g., taste substance and/or aroma substance) by foaming a polyurethane-urea dispersion, drying that dispersion and incorporating the sensorially active substance into the polyurethane-urea dispersion before, during or after foaming of the dispersion.
