Water-Based Semi-Permanent Anti-Vibration Rubber Mold Release Agent for Automotive Parts

Lubekote 9421A/9140 is a premium water-based semi-permanent mold release agent specifically formulated for anti-vibration rubber components used in automotive and industrial applications. Engineered with advanced polymer dispersion technology, this release agent forms a durable, micro-thin coating on mold surfaces that delivers consistent, high-performance demolding across multiple production cycles.

Unlike traditional release agents that rely on wax, stearic acid, or silicone oil, Lubekote 9421A/9140 provides a clean, non-transferring release that preserves the dimensional accuracy and surface quality of molded anti-vibration parts such as engine mounts, suspension bushings, and vibration dampers.

As an environmentally responsible solution, the water-based formulation eliminates the need for hazardous solvents commonly found in conventional mold release products. This not only reduces VOC emissions in your production environment but also simplifies workplace safety compliance and waste disposal procedures.

Lubekote 9421A/9140 is engineered for the demanding requirements of anti-vibration rubber component manufacturing. It performs exceptionally well with natural rubber (NR), styrene-butadiene rubber (SBR), nitrile rubber (NBR), and ethylene propylene diene monomer (EPDM) compounds.

Primary application areas include automotive engine mounts and torque struts, suspension bushings and control arm isolators, exhaust system hangers and vibration dampers, industrial machinery vibration isolation pads, railway and marine anti-vibration mounts, and general molded rubber parts requiring clean, residue-free release.

The water-based formulation is compatible with both metal and non-metal mold surfaces including steel, aluminum, and epoxy composite tooling.

Lubekote 9421A/9140 is available in standard packaging options of 20kg/barrel and 200kg/drum, with customized packaging solutions available upon request to meet specific production line requirements.

Each batch undergoes rigorous quality control testing including viscosity measurement, pH verification, coating adhesion testing, and multi-cycle release performance evaluation on standard rubber compounds. Our ISO 9001:2015 certified manufacturing facility ensures batch-to-batch consistency and reliable performance.

Technical data sheets (TDS) and material safety data sheets (MSDS) are available upon request.
