What is Part VII ACID Catalyzed PNB and Blown No-Bake about?

This technical paper discusses the phenolic no-bake (PNB) sand binder system, highlighting its introduction, properties, and operational considerations. It emphasizes the advantages of PNB over furan no-bake systems, particularly during shortages of furan resins, and outlines the environmental and reclamation challenges associated with PNB. Additionally, the paper details the blown no-bake (BNB) process for core and mold making, showcasing its innovations and techniques for achieving uniform density in core
