Silicone Rubber Release Water Dilutable Surfactant Lubricant, Spray-On Mold Surface for Easy Demolding
Silicone Rubber Release Water Dilutable Surfactant Lubricant is a water‑dilutable non‑silicone surfactant‑type releasing concentrate dedicated for silicone rubber mold surface treatment. It can be diluted with clean water before spraying onto pre‑heated mold cavities. As water evaporates, a thin durable lubricating isolating film is formed on the metallic mold surface. It facilitates clean demolding of complex silicone rubber molded articles during high‑temperature vulcanization. This water‑born
Product Detail Page: This water dilutable mold release lubricant is manufactured by blending selected high‑performance surfactants, wetting agents and film‑forming auxiliaries in deionized water, followed by homogenization and fine filtration. Each production batch is tested for pH value, dilution stability, drying film‑forming performance, heat resistance, lubricating effect and residual tendency test before shipment.
Silicone rubber hot vulcanization compression molding brings persistent production challenges. Conventional solvent‑based silicone spray release agents introduce flammable volatile vapors inside the workshop, creating fire risks and health concerns for operators. Direct silicone‑oil‑containing releasing sprays leave silicone residues on molded silicone parts; such residues severely impair subsequent surface printing, bonding and coating processes. Many inferior water‑dilutable release concentrates exhibit poor wetting performance on polished steel mold surfaces. They produce discontinuous spotted films after water evaporation. Discontinuous lubricating layers cause local sticking, tearing and blemishes on silicone rubber components. Repeated molding cycles allow cross‑linked silicone debris to accumulate on mold cavities, which forces frequent production stops for mold cleaning and lowers overall equipment utilization.
After proper dilution with deionized water according to recommended dilution ratio, this surfactant‑based releasing lubricant is evenly sprayed onto thoroughly cleaned and pre‑heated mold cavities. Water quickly evaporates under mold temperature, leaving a uniform thin non‑silicone lubricating isolating film attached to the metal mold surface. This low‑friction boundary layer reduces interfacial adhesion between hot silicone rubber stock and mold steel during high‑pressure vulcanization. It enables easy demolding of intricately shaped silicone rubber parts. Since the formulation does not contain free silicone oil, harmful silicone transfer residues on molded rubber goods are avoided. It helps preserve downstream printing and adhesive bonding capability of finished silicone articles, and slows the build‑up of cross‑linked silicone fouling on mold surfaces during continuous molding runs.
Strict control of on‑site dilution ratio, spray volume and mold drying time is critical. Excessive dilution leads to insufficient film‑forming capacity, resulting in incomplete isolating layer, rubber sticking and surface tearing. Over‑spraying generates an overly thick lubricating film, which may leave visible smudge marks on the surface of cured silicone parts. Practical molding trials on customer production molds are strongly recommended before formal mass‑scale deployment. This surfactant‑based release lubricant is suitable for peroxide‑cured heat‑vulcanized silicone rubber compression molding.
For processing operations: Dilute the concentrate with deionized water to working concentration; perform uniform spray application on pre‑cleaned pre‑heated mold cavities; allow sufficient drying time before charging silicone rubber stock for vulcanization.
Major application fields: water‑dilutable spray‑on mold surface releasing treatment for heat‑cured silicone rubber compression molding; non‑silicone mold lubricant for silicone rubber component manufacturing; low‑VOC mold preparation auxiliary for silicone vulcanization workshop.
Store the product in tightly‑sealed original plastic containers within 10‑25℃, protect from freezing, avoid direct sunlight and prolonged high‑temperature warehouse storage.
