523 and 683 Binders

metal cast partsEmulsified Core Binders for Green Sand Metalcasting Foundry

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.

Features

  • Direct substitute for core oils
  • No special or new equipment required for production and no special emission control equipment necessary
  • Easily pumped from bulk storage
  • Good sand flowability. No sticking in boxes whether blown or hand rammed
  • Good collapsibility - excellent sand reclamation
  • Reduced emissions and smoke
  • No fire hazard
  • Optimum baking temperatures are reduced

Application   

523 and 683 EMULSIFIED CORE BINDERS are used the same way a conventional or solventless core oil is used. For initial trials it is recommended that the 523 and 683 EMULSIFIED CORE BINDERS be substituted directly into the current sand mix at the same percentage as the core oil. It may be necessary to increase binder levels by 1/2% over conventional core oil. Because the smoke producing solvents have been replaced with water, it may also be necessary to reduce the water content in the sand mix by 1/3 to 1/2.

Generally, the 683 EMULSIFIED CORE BINDER is used when higher strengths are desired and/or if the sand mix contains Bentonite.

Used as a Core Oil Replacement

(523 Emulsified Core Binder)

Features elimination of the smoke normally encountered when baking out cores made with conventional core oils.

Suggest initially replacing core oil with the same amount of 523 Core Binder. Since the smoke producing solvents in conventional Core Oils have been replaced with water, you may have to reduce the water by 1/3 to 1/2 of that used in the regular oil sand mix.

Kerosene in the sand mix as a release agent is not required.

Do not use Bentonite in the sand mix as soft cores will result.

Baking temperature 350 - 425o F.
