Abstract

Procedure for obtaining sheets and coating or adhering flexible substrates, with polyurethane or polyurethane-ureas, especially textiles, characterized in that polyurethanes or powdery polyurethane-ureas that: 1. have a smooth, spherical surface; 2. an average diameter between 5 and 200 μ 3. an ion group content of 1 to 15 milliequivalents per 100 g; 4. a step resistance of 1010 to 1014 ohms, cm; and 5. in which the development of the corresponding IMI curves at temperatures between 110ºC and 250ºC represents the ascending arm of a parabola by varying the IMI value in a temperature interval from 5 to 50ºC from 2 g for 10 minutes to 50 g for 10 minutes, it is applied dry on a separating support or a flexible substrate and then it is sintered by heat and/or melts and, if necessary, it is still calendered.
