Blended furnish with improved performance and methods of making and using the same

A method for preparing a blended furnish, comprising:

• adding a plurality of substrates;
• mixing a melamine-urea-formaldehyde (MUF) resin with an amine and water at a pH of 5-11, preferably pH of 6 to pH below 10;
• optionally adding one or more additives;
• adding a lignosulfonate salt and does not contain a kraft lignin;
• optionally adding one or more additives to form the blended furnish,
• wherein the melamine-urea-formaldehyde (MUF) resin is made prior to mixing with the lignosulfonate,
• wherein the amine is from about 0.0 wt. % to about 1 wt. % based on the total weight of the blended furnish, and
• 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.
