Core Binders

Core & Mold Coatings

EZ Kote™ Refractory Core & Mold coatings are formulated for ferrous & non-ferrous castings. The formulation permits use on small intricate cores up to heavy cores and molds.

Emulsified Core Binders

Hill and Griffith 523 and 683 EMULSIFIED CORE BINDERS are formulated with water, drying type oils, surfactants, cross-linking resins, hardeners and biocides to produce a stable emulsion used in making sand shapes. 523 and 683 EMULSIFIED CORE BINDERS were developed to meet increasing environmental demands set forth by the Environmental Protection Agency.

Sodium Silicate Binders

Hill and Griffith Sodium Silicate Binders, Corosil and CoBond 86, are formulated with water based solutions of Sodium Silicates and collapsibility agents. These binders are available in various percentages of carbonaceous materials as well as silica to soda ratios for varied or specific applications. The sand and silicate mixture is hardened by gassing with carbon dioxide (CO2). Molds or cores produced with Silicate binders result in castings with minimal veining, scabbing and penetration. Due to lack of mold wall movement, dimensional accuracy may be improved over some other casting processes.

Other Core Binders

GOULAC* is a dark colored water soluble, material developed from the wood pulping process and used primarily as a foundry core binder.
