This water‑based semi‑permanent fluorosilicone mold release agent is a stabilized aqueous fluorosilicone dispersion formulated with modified fluorosilicone active substance, high‑purity non‑ionic dispersants, wetting additives and deionized‑water carrier. It is designed for semiconductor encapsulation and precision electronic plastic‑rubber component molding. After dilution and spraying onto properly pre‑heated mold surfaces, water evaporates to form a thin, tough fluorosilicone release coating.

Product Detail

Product Detail Page: The product is produced via high‑speed homogenizing dispersion of functional fluorosilicone in deionized‑water under clean production conditions. Carefully screened dispersants prevent fluorosilicone particles from settling and flocculating during storage. Multi‑stage fine filtration removes oversized agglomerated particles. Each production batch is subjected to stability testing, residual‑level inspection and actual molding validation to satisfy strict cleanliness specifications for semiconductor‑related molding workshops.

Semiconductor packaging and precision electronic component manufacturing impose extremely stringent cleanliness requirements on mold release auxiliaries. Conventional general‑purpose release agents often leave micro‑residues. These tiny contaminants may trigger surface defects, delamination and electrical performance failures on encapsulated semiconductor devices. Temporary release agents that only last for one molding cycle demand frequent re‑spraying, which extends cycle time and introduces extra foreign‑particle pollution, resulting in reduced product yield. Many solvent‑based semi‑permanent release agents contain volatile flammable components, creating explosion and health hazards inside closed electronic clean‑room production areas.

After accurate dilution with high‑purity deionized water, the dispersion is sprayed onto thoroughly cleaned and pre‑heated mold surfaces. Water evaporates rapidly under controlled mold temperature, and fluorosilicone components fuse to generate a continuous, thin and durable separating barrier. This anti‑adhesive film withstands elevated temperatures during epoxy encapsulation and precision rubber‑plastic molding. It permits several consecutive molding cycles before re‑coating, cutting down production interruptions. The optimized fluorosilicone molecular structure effectively minimizes migration onto molded workpieces, keeping surface micro‑residues at a very low level, which is critical for boosting finished‑product yield of semiconductor and precision electronic components.

Even with low‑residue formulation, gradual mechanical abrasion and thermal aging of the release film still occur after repeated molding cycles. Operators must inspect mold surface condition and finished‑part quality periodically. Once early sticking signs or minor surface haze are observed, stop production for thorough mold cleaning and re‑apply release agent. Over‑spraying must be strictly avoided; excessive deposition will slowly build up baked residues inside precision micro‑structured mold cavities, causing tiny surface flaws on delicate electronic parts. Although residual level is low, preliminary compatibility testing on parts requiring subsequent coating or bonding is still strongly recommended before mass production.

For workshop operation, thoroughly purge old release residues from mold surfaces. Dilute the concentrated dispersion with deionized‑water following technical datasheet instructions. Adjust mold to specified pre‑heating temperature before spraying. Apply an extremely thin, uniform coating. Determine re‑spraying interval based on actual molding results. In clean‑room environments, comply with local clean‑room operating protocols.

Prevent foreign particulate contamination, freezing and prolonged high‑temperature storage. Freezing will break dispersion stability and cause irreversible fluorosilicone sedimentation.

Major application fields: semi‑permanent mold release for semiconductor epoxy encapsulation; demolding auxiliary for precision electronic rubber‑plastic components; low‑residue releasing agent for high‑yield precision electronic molding production.

Store the product in tightly‑sealed original plastic drums within 5‑25℃. Protect against frost and direct sunlight. Gentle stirring is required before using long‑term stored concentrated batches.
