This modified‑silicone die‑casting release agent is a water‑dilutable industrial formulation composed of specially modified silicone components, high‑temperature lubricants, surface wetting additives and anti‑carbonation agents. It is designed for high‑pressure die‑casting production of aluminum, magnesium and zinc alloy parts. After dilution and spraying onto hot mold surfaces, water evaporates rapidly to build a thin heat‑resistant separating lubricating layer. It effectively reduces metal adh

Product Detail

Product Detail Page: The release agent is produced by emulsifying custom‑modified silicone with selected functional additives under high‑shear mixing conditions. Raw‑material selection excludes conventional high‑molecular‑weight straight‑chain silicone that tends to crack and form carbon deposits under intense thermal shock inside die‑casting molds. Strict filtration is performed during production to remove insoluble impurities, guaranteeing stable emulsion properties for long‑term circulation through spray nozzles on die‑casting machines.

High‑pressure die‑casting of aluminum, magnesium and zinc alloys subjects mold surfaces to repeated violent thermal shock. Conventional die‑casting release agents often suffer thermal decomposition inside hot mold cavities, leaving stubborn carbon‑based residues. Gradual carbon build‑up roughens mold surfaces, creates blemishes, blisters and indentations on casting surfaces. In many cases, heavy residual contamination renders alloy workpieces unsuitable for painting, requiring extra degreasing and cleaning procedures. Frequent mold cleaning shutdowns reduce foundry output and raise overall manufacturing costs.

After proper dilution with clean water, the emulsion is sprayed onto pre‑heated die‑casting mold surfaces. Fast water evaporation leaves behind a uniform thin lubricating separating film. This protective layer withstands instantaneous high‑temperature contact with molten aluminum, magnesium or zinc alloy. It inhibits molten metal soldering onto mold steel and suppresses thermal decomposition that forms carbon deposits. Continuous die‑casting cycles can be run with extended intervals between mold cleaning. The casting surface stays relatively clean, making the alloy parts post‑paint ready for powder coating, liquid spray painting and electrophoretic coating.

Even with anti‑carbon‑build‑up formulation, improper over‑spraying will still cause residual accumulation inside mold runners and vents. Operators should optimize spraying time, spray volume and nozzle position according to casting weight, injection speed and mold temperature. Periodic mold maintenance cleaning is still necessary for long‑term mass production. If cast parts require high‑grade surface finishing, preliminary surface degreasing inspection is recommended before painting.

For workshop operation, dilute the concentrated release agent with fresh water following technical data sheet dilution ratio. Ensure the mold reaches the targeted operating temperature before spraying. Adjust spray coverage to achieve thin and even film formation, avoid excessive local deposition.

Protect the concentrate from foreign debris contamination, freezing and prolonged high‑temperature storage. Freezing will destroy emulsion stability and cause irreversible phase separation.

Major application fields: release auxiliary for high‑pressure die‑casting of aluminum structural components; magnesium alloy die‑cast hardware parts; zinc‑alloy decorative die‑casting components; foundry production where castings require subsequent painting and surface coating.

Store the product in tightly‑sealed original plastic drums within 5‑35℃. Prevent frost and direct sunlight. Gentle stirring is required before diluting long‑stored concentrated batches.
