Abstract
Methods for producing spray-dried phenol-formaldehyde resole resins and products made therefrom. The method can include spray-drying an aerated liquid phenol-formaldehyde resole resin containing about 0.02 wt % or more of a surfactant, based on a combined weight of the liquid phenol-formaldehyde resole resin and the surfactant, to produce a spray-dried phenol-formaldehyde resole resin powder.
