Correct Usage of Die Casting Release Agents: 100 Q&A on Die Casting Release Agents (2)

(1) Dilution Ratio

Adjust the appropriate dilution ratio based on solid content, spraying time, and process requirements. Generally, the higher the solid content, the longer the spraying time, or the simpler the process demands, the higher the dilution multiple.

(2) Avoid Bubbling or Blowing

Do not use bubbling machines or stirrers to agitate the release agent with air bubbles. This can easily cause ​demulsification​ (precipitation of active ingredients), compromising demolding performance, clogging nozzles, and reducing effectiveness.

(3) Purified Water for Dilution

Preferably use purified water for dilution; minimize reliance on tap water or groundwater. Groundwater contains high levels of calcium and magnesium ions, which can lead to carbon deposition in castings.

(4) Odor Prevention

Use the release agent promptly after opening to reduce odor development from bacterial growth. For extended usage cycles, always use a clean container to scoop the agent—this prevents contamination and deterioration.

(5) Storage Conditions

Store in a cool, shaded place, ideally between 5°C and 35°C. Extreme cold (causing repeated freeze-thaw cycles) or heat can easily trigger demulsification and active ingredient precipitation.

(6) Light Agitation Before Use

If stored for a long time, gently shake the bucket before use. Clean the stirring rod thoroughly beforehand to avoid cross-contamination.

(7) Correct Pouring Method

Pour the ​release agent concentrate​ into water (never add water to the concentrate). Reverse emulsification (adding water first) will disrupt the dilution ratio and performance.

(8) Spraying Distance

Generally, maintain a spraying distance of 80–200mm from the mold surface.
