The present invention relates to the manufacturing of honeycomb sandwich panels. Particularly a two component polyurethane adhesive having a Polyol P1 with a bisphenol-A or bisphenol-F moiety in its structure, a polyester or polyether Polyol P2, a heat-activated polyurethane catalyst CA and a polyisocyanate P1. The adhesive is remarkably well suited for the manufacturing of honeycomb sandwich panels showing particularly a short curing time combined with a long open time and good wetting and bonding properties.
