Exterior Adhesive from Sulfite Mill Effluent

Abstract : Poplar waferboards bonded with ammonium-based spent sulfite liquor (SSL) binder and properly hot pressed could readily meet the CAN 3-0188.2-M78 requirements. The abundance of SSL at low cost allows the massive use of SSL binder in waferboard production, resulting in a better quality waferboard, yet at a low production cost. (Author)
