Abstract
Disclosed is a method for treating wood veneer, including the steps of providing at least one sheet of wood veneer; coating at least one side of the sheet of wood veneer with an aqueous coating composition including nanocellulose to obtain a coated sheet of wood veneer; and drying the coated sheet using compression pressure and heat. Also disclosed is a coated wood veneer including a sheet of wood veneer and a coating including nanocellulose arranged on at least one surface of the sheet.
Claims16
A method for treating wood veneer, the method comprising:
- providing at least one sheet of wood veneer;
- coating at least one side of the at least one sheet of wood veneer with an aqueous coating composition comprising nanocellulose in an amount between 4 to 18% by weight, calculated of the weight of the total coating composition, the nanocellulose having apparent viscosity between 8,000 and 22,000 mPa·s after the aqueous coating composition comprising the nanocellulose is mixed for about 10 minutes at about 300 rpm and then mixed for about 2 minutes at 14,000 rpm, in a consistency of 5% by weight at a temperature of 20 ° C. to obtain a coated sheet of wood veneer;
- and
- drying the coated sheet using compression pressure and heat.
