- a lignosulfonate, a kraft lignin or a sulfonated lignin;
- a deep eutectic solvent;
- an alkaline compound;
- optionally an additive;
- and
- a plurality of substrates,
- wherein the blended furnish has a buffer capacity of 2-200 mL of 0.1 N HCl by the Acid Titration Value (ATV) Method using 20 grams of blended furnish for a period of time up to 20 days.

A method for preparing a blended furnish, comprising:
- adding a plurality of substrates;
- mixing a urea-formaldehyde (UF) resin or a melamine-urea-formaldehyde (MUF) resin optionally with an amine and water at a pH of 5-11, preferably 6-10;
- optionally adding one or more additives;
- adding a lignosulfonate salt, a kraft lignin or a sulfonated lignin and a deep eutectic solvent;
- optionally adding one or more additives to form the blended furnish,
- wherein the blended furnish has a buffer capacity of 2-200 mL of 0.1 N HCl by the Acid Titration Value (ATV) Method using 20 grams of blended furnish for a period of time up to 20 days.
