A method of scavenging formaldehyde from a wooden composite comprising urea-formaldehyde or melamine urea-formaldehyde, the method comprising: providing a furnish for at least one of a core layer and a face layer, providing at least one of a first formaldehyde scavenger (FS-C) and a second formaldehyde scavenger (FS-F); wherein the first formaldehyde scavenger (FS-C) comprises at least one of K 2 S 2 O 8, (NH 4) 2 S 2 O 8, and Na 2 S 2 O 8, and optionally comprising ammonium polyphosphate (NH 4) 3 PO 4, NH 4 H 2 PO 4, (NH 4) 2 HPO 4, (NH 2) 2 CO, (NH 4) 2 SO 4 and combinations thereof; wherein the second formaldehyde scavenger (FS-F) comprises at least (NH 2) 2 CO and [NH 2 OH·HCl] and optionally comprises K 2 S 2 O 8, (NH 4) 2 S 2 O 8, Na 2 S 2 O 8, ammonium polyphosphate (NH 4) 3 PO 4, NH 4 H 2 PO 4, (NH 4) 2 HPO 4, (NH 4) 2 SO 4, and combinations thereof; providing an urea-formaldehyde uncured resin or a melamine urea-formaldehyde uncured resin, wherein each uncured resin comprises an adhesive and a catalyst; mixing at least one of the following combinations i) the first formaldehyde scavenger (FS-C), the uncured resin and the furnish of the core layer; ii) the second formaldehyde scavenger (FS-F), the uncured resin and the furnish of the face layer; iii) the first formaldehyde scavenger (FS-C), the uncured resin and the furnish of the face layer; and iv) the second formaldehyde scavenger (FS-F), the uncured resin and the furnish of the core layer, producing at least one core layer having two sides from any one of i), ii), iii) and iv) combinations; applying at least one face layer on each of the sides of the core layer from any one of i), ii), iii) and iv) combinations; curing the core layer and the two face layers, the solid weight of formaldehyde scavenger (FS-F) is 15 to 20 wt% of the total weight solids of resin in the face layer, whereby scavenging formaldehyde from the wooden composite. providing a furnish for at least one of a core layer and a face layer, providing at least one of a first formaldehyde scavenger (FS-C) and a second formaldehyde scavenger (FS-F); wherein the first formaldehyde scavenger (FS-C) comprises at least one of K 2 S 2 O 8, (NH 4) 2 S 2 O 8, and Na 2 S 2 O 8, and optionally comprising ammonium polyphosphate (NH 4) 3 PO 4, NH 4 H 2 PO 4, (NH 4) 2 HPO 4, (NH 2) 2 CO, (NH 4) 2 SO 4 and combinations thereof; wherein the second formaldehyde scavenger (FS-F) comprises at least (NH 2) 2 CO and [NH 2 OH·HCl] and optionally comprises K 2 S 2 O 8, (NH 4) 2 S 2 O 8, Na 2 S 2 O 8, ammonium polyphosphate (NH 4) 3 PO 4, NH 4 H 2 PO 4, (NH 4) 2 HPO 4, (NH 4) 2 SO 4, and combinations thereof; providing an urea-formaldehyde uncured resin or a melamine urea-formaldehyde uncured resin, wherein each uncured resin comprises an adhesive and a catalyst; mixing at least one of the following combinations i) the first formaldehyde scavenger (FS-C), the uncured resin and the furnish of the core layer; ii) the second formaldehyde scavenger (FS-F), the uncured resin and the furnish of the face layer; iii) the first formaldehyde scavenger (FS-C), the uncured resin and the furnish of the face layer; and iv) the second formaldehyde scavenger (FS-F), the uncured resin and the furnish of the core layer, i) the first formaldehyde scavenger (FS-C), the uncured resin and the furnish of the core layer; ii) the second formaldehyde scavenger (FS-F), the uncured resin and the furnish of the face layer; iii) the first formaldehyde scavenger (FS-C), the uncured resin and the furnish of the face layer; and iv) the second formaldehyde scavenger (FS-F), the uncured resin and the furnish of the core layer, producing at least one core layer having two sides from any one of i), ii), iii) and iv) combinations; applying at least one face layer on each of the sides of the core layer from any one of i), ii), iii) and iv) combinations; curing the core layer and the two face layers, the solid weight of formaldehyde scavenger (FS-F) is 15 to 20 wt% of the total weight solids of resin in the face layer, whereby scavenging formaldehyde from the wooden composite.
