Abstract: THE PRESENT INVENTION RELATES TO A METHOD FOR THE REDUCTION OF THE FORMALDEHYDE EMISSION OF WOOD-BASE MATERIALS BY APPLICATION OF NITROGEN-CONTAINING COMPOUNDS, WHEREIN I.A MIXTURE WHICH COMPRISES AT LEAST ONE POLYAMINE AND, IF APPROPRIATE, UP TO 20% BY WEIGHT, BASED ON THE MIXTURE, OF UREA IS APPLIED TO THE WOOD-BASE MATERIAL; II.POLYAMINE IS APPLIED ON OR IN THE PARTICLE OR FIBER CAKE; III.POLYAMINE IS APPLIED TO THE COATING SUBSTRATE USED FOR SURFACE FINISHING AND/OR IV.POLYAMINE IS APPLIED TO THE EXPOSED AREAS; THE POLYAMINES HAVING A MOLECULAR WEIGHT OF AT LEAST 500 G/MOL AND AT LEAST 6 PRIMARY OR SECONDARY AMINO GROUPS.
