GOULAC* - Core Oil Combinations:

To reduce required oil additions and minimize baking time, substitute 25 to 33% GOULAC* for present core oil additions. Cores made with 75% core oil and 25% GOULAC* dry in about 1/2 the time of standard core oil mixes. Savings are realized through reduced core oil additions and lower fuel costs from reduced baking time.

GOULAC* - Cereal Combinations: GOULAC*

when combined with any cereal can be used to replace core oil and reduce binder cost. Baking time is reduced and green and dry strengths are improved.

GOULAC* - Pitch Combinations: GOULAC*

may be used as a partial replacement to reduce the use of pitch compound up to one-half. Use GOULAC* as follows:

  • Add GOULAC* on an equal weight basis.
  • Mixture reduces core box cleaning time and minimized labor costs.

WARNING:

GOULAC* will pick up moisture from atmosphere. Keep open bags in Covered Containers.
