This water‑based semi‑permanent silicone release agent is a functional aqueous silicone emulsion composed of modified silicone active substances, non‑ionic emulsifiers, slip‑enhancing additives and deionized‑water carrier. Free from strong volatile organic solvents, it features low‑odor and eco‑friendly properties. After dilution and spraying onto pre‑heated hot‑mold surfaces, water evaporates rapidly to form a tough, high‑slip silicone separating film. The durable release layer permits several

Product Detail

Product Detail Page: Manufactured via high‑pressure emulsification of specially modified silicone fluid in deionized‑water, this release agent adopts carefully‑selected non‑ionic emulsifiers to maintain stable emulsion state during storage and dilution. Slip‑promoting functional additives are incorporated to enhance surface lubricating performance of the dried silicone film. Finished emulsion passes fine filtration to eliminate agglomerated colloidal particles. Each production batch is tested for emulsion stability, film‑forming property and demolding performance prior to shipment.

Hot‑mold rubber vulcanization and thermoset plastic compression molding present persistent production challenges. Conventional temporary water‑based release agents lose releasing capability after only one molding cycle, requiring frequent re‑spraying that interrupts continuous production. Many common semi‑permanent solvent‑borne release agents contain volatile flammable solvents, which bring explosion hazards and poor workplace air quality. If the release film exhibits insufficient slip property, hot cured rubber or plastic parts tend to stick locally, causing tearing, edge damage and surface defects upon ejection.

When properly diluted with clean deionized water and sprayed onto pre‑heated mold cavities, water quickly vaporizes under mold temperature. A continuous, tough and high‑slip silicone barrier is deposited on the metallic mold surface. This durable non‑stick coating resists thermal stress during repeated hot curing cycles. It effectively prevents hot rubber compound and cross‑linking thermoset plastic from adhering to mold steel, facilitates smooth ejection of finished workpieces, and allows multiple molding cycles before re‑coating is required. This release agent is applicable for hot compression molding, transfer molding of various vulcanized rubber and thermoset plastic items.

Although it delivers semi‑permanent working performance, the silicone release coating will gradually suffer mechanical abrasion and thermal aging after repeated hot cycles. Operators should closely observe demolding conditions and workpiece surface quality. Once sticking tendency or haze appears on molded parts, the mold should be thoroughly cleaned and re‑coated. Excessive spraying dosage shall be avoided; heavy build‑up of silicone residues inside mold cavities may generate oily blemishes on molded components. Residual silicone traces on finished rubber and plastic parts may impair subsequent painting, printing or bonding processes; relevant surface cleaning is required if post‑finishing is needed.

For on‑site workshop usage, dilute the concentrated emulsion to recommended working concentration with deionized water. Ensure the mold reaches the specified pre‑heating temperature before spraying. Apply thin and uniform spray coating. Monitor demolding performance on‑site to determine proper re‑spraying intervals.

Protect the concentrated emulsion from foreign debris contamination, freezing and prolonged high‑temperature storage. Freezing will break the emulsion and trigger irreversible phase separation.

Major application fields: semi‑permanent mold release for hot‑mold vulcanized rubber components; releasing auxiliary for hot compression‑molded thermoset plastic workpieces; eco‑friendly aqueous releasing agent for continuous hot‑mold rubber‑plastic production lines.

Store the product in tightly‑sealed original plastic drums within 5‑30℃. Prevent frost and direct sunlight. Gentle mechanical stirring is required before using long‑term stored concentrated batches.
