High flow urea-formaldehyde powders for particleboard and fiberboard manufacture

摘要

Particulate binder compositions made with amine-aldehyde resins and methods for making same are provided. The method for making the particulate binder composition can include spray-drying an amine-aldehyde resin having a total aldehyde compound to total amine compound molar ratio of about 1.55: 1 to about 1.65: 1 to produce a particulate binder composition. The particulate binder composition can have a fusion diameter of about 35 mm to about 70 mm.
