Method of gluing wood-based products by means of amino-resin-based adhesives. In the method, the amino resin is cured with a hardener composition containing alkylamine salts selected from a group consisting of the following compounds: NH2((CH2)nNH)mH x lX wherein n = 2 - 5, m = 1 - 3, l = 1 - 4, and X is an organic or inorganic acid; in formula (I) R = H or CH2CH2NH2 and X an acid as above and l = 1 - 3; and CH2CH2(NHCH2CH2CH2NH2)2 x lX wherein l = 1 - 4 and X has the same meaning as above. The invention also relates to a hardener composition for the amino resin, which composition contains alkylamine salts as stated above. Preferred alkylamine salts are ethylenediamine dihydrochloride and ethylenediamine disulfamic acid. |
