Abstract
The subject invention relates to compositions and methods for the preparation of stucco slurry compositions. The compositions and methods involve replacing typically used starches with modified high amylose starches that can be used in the normal wallboard manufacturing process. The compositions and methods provide wallboards having increased core strength and increased paper-to-core bond integrity compared to standard wallboards made from slurries with reduced water levels.
