Georgia-Pacific Chemicals manufactures an extensive line of PHENOLIC RESINS for foundry applications.
Our solid RESI-FLAKE® resins were developed for use in the production of foundry shell molds and cores by the hot-sand process. Liquid RESI-SHELL® resins are used in the production of foundry shell molds and cores by the warm air sand process. RESI-SET® liquid resins are specifically designed for the foundry no-bake process.
These products feature varying degrees of melt points, tensile strength, peel-back resistance or other properties. There is also a line of phenolic powders for use in shell glue binders. Examples of the products are below:
