Abstract (en)
[origin: WO2014076206A1] The invention relates to a two-component polyurethane adhesive, comprising a polyol component containing a) 2 to 30 wt% of at least one oleochemical polyol having a molecular weight greater than or equal to 500 g/mol, b) 5 to 35 wt% of at least one 3 to 14 functional polyol, c) 5 to 35 wt% of at least one polyol based on ethoxylated or propoxylated polyphenols, d) 0 to 20 wt% of at least one additional polyol, e) 2 to 65 wt% of at least one additional additive, wherein the sum of a) to e) should be 100 wt%, and an isocyanate component containing at least one aromatic polyisocyanate and at least one aliphatic polyisocyanate in an NCO/OH ratio of 0.9:1 to 1.5:1, wherein the cross-linked adhesive has a Tg greater than or equal to 65°C. The invention further relates to the use of such adhesives.
