Abstract: A resorcinol-modified phenolic resin composition is formed by reacting a basic catalyst, formaldehyde, water and a benzene-ol to form an intermediate composition to which resorcinol is subsequently added to reduce the presence of free formaldehyde. Optionally, an alkanolamine can be combined and reacted with the resorcinol-modified phenolic resin composition to form a resorcinol-alkanolamine-modified phenolic resin composition. The resorcinol-modified phenolic resin and the resorcinol-alkanolamine-modified phenolic resin compositions can be employed to coat abrasive products having a relatively low free formaldehyde content.
