In a previous paper, the laboratory preparation and properties of phenol-formaldehyde resins employing sodium carbonate and sodium hydroxide as catalysts were presented. In addition, the preparation and properties of highpressure decorative laminates produced from these resins were discussed. In order to extend and amplify the laboratory results, it was necessary to scale up the laboratory experiments. The sodium carbonate catalyzed phenolic resins were prepared in 5-gal resin kettles and evaluated for yield, free formaldehyde content, and water dilutability. Subsequent pilot plant paper treating, pilot plant laminating, and laminate evaluation were conducted. Resin preparation and laminate properties are compared for the sodium carbonate and sodium hydroxide catalyzed systems.
