ABSTRACT:
This invention relates to a powdered phenolic resin composition suitable for the production of dry processed resinbonded felt. The phenolic resin composition imparts a good release of the felt from the heated platen or belt and has a rapid cure rate. The powdered phenolic composition is composed of a novolac type phenolic resin, or a mixture of novolac and resole type with an aromatic carboxylic acid as an additive. The resin mixture has a bulk density of 0.29-0.36 gm/cm.sup.3, and contains 0.3-5 parts by weight of the aromatic carboxylic acid to 100 parts by weight of phenolic resin. Said aromatic carboxylic acid has the formula
