Abstract
The invention relates to a two-component polyurethane adhesive containing i) a polyol component including a mixture of three different polyols to ensure crosslinking for a mechanically stable adhesive bonding, and also to achieve hydrophobia to ensure that the crosslinked adhesive layer is impervious to moisture, and glass fibers, and ii) an isocyanate component containing polyisocyanates in an NCO/OH ratio of 0.9:1 to 1.5:1. The polyol component further includes a metal catalyst. The two-component adhesive has a high adhesive strength, a high glass temperature, a low curing time and a sufficiently long processing time, which can adhesively bond also substrates having uneven surfaces. The invention further relates to an article comprising the two-component polyurethane adhesive.
