PROBLEM TO BE SOLVED: To provide a honeycomb sandwich panel and the use of a two-component polyurethane adhesive in the production of the same. SOLUTION: Preferably, the two-component polyurethane adhesive comprises a polyol P1 having a bisphenol A or bisphenol F moiety in its structure; a polyester or polyether polyol P2; a thermally-activated polyurethane catalyst CA; and a polyisocyanate PI. The adhesive is substantially suitable for the preparation of a honeycomb sandwich panel, and exhibits extra-shortened hardening time, a longer open time, better wettability and binding performance.
