2K POLYURETHANE SYSTEMS WITH A HIGH GLASS-TRANSITION TEMPERATURE |
摘要 |
The invention relates to a two-component polyurethane composition with a viscosity of 20 mPas to 3000 mPas (EN ISO 2555, 25 °C), containing i) 10 to 80 wt.% of at least one polyol with an average molecular weight of 200 g/mol to 3000 g/mol, ii) 5 to 70 wt.% of at least one polyisocyanate, and iii) 0 to 10 wt.% of a catalyst. The composition has an NCO:OH ratio of 2:1 to 1:2, and polyisocyanates are used as the polyisocyanates, wherein 3 to 25 mol% of the NCO groups of the isocyanate is converted into carbodiimides and/or uretonimine. The two-component polyurethane compositions are used as matrix binders for fiber composite molded bodies. |
