Water-Based Semi-Permanent VOC-Free Seal Release Agent for Rubber Molding

Lubekote 9165C is a high-performance, water-based sealer release agent specifically engineered for the rubber industry. This innovative formula creates a durable, protective barrier on mold surfaces, facilitating easy demolding of even the most challenging rubber compounds. Its unique sealer property ensures a flawless surface finish by preventing knit lines, making it an indispensable solution for manufacturers of natural rubber, EPDM, acrylic ester, vinyl acrylate, and demanding elastomers like fluororubber and HNBR.

As a specialized sealer release agent, Lubekote 9165C addresses two critical needs simultaneously: it acts as an effective mold release and seals the mold surface to prevent defects. This water-based emulsion forms a resilient film that withstands the molding process, providing numerous release cycles before reapplication is needed. Its non-transferring formula ensures that final rubber parts are not contaminated, preserving their inherent properties and readiness for secondary operations.

• Superior Sealer Properties: Effectively seals mold surfaces to prevent knit lines and air traps
• True Semi-Permanent Performance: Delivers multiple consistent release cycles per application
• Water-Based & VOC-Free: Contains no solvents or volatile organic compounds
• Extremely Low Transfer: Minimizes migration onto molded parts to prevent contamination
• Broad Material Compatibility: Suitable for natural rubber, EPDM, acrylic ester, vinyl acrylate, fluororubber, and HNBR
• Ready-to-Use Convenience: Requires no mixing straight from the container

For optimal results, begin with a meticulously cleaned mold. Shake or stir the product thoroughly before use. Apply a single, thin, uniform coat to the mold surface using spray or cloth. Allow the water carrier to evaporate completely before initiating the molding cycle. Reapplication is only necessary after several successful demolding cycles.

For industrial use only. Avoid prolonged skin contact and use appropriate personal protective equipment. In case of eye contact, rinse immediately with plenty of water and seek medical advice. Do not allow the product to freeze, and store in a cool, dry place to maintain efficacy throughout its 12-month shelf life.

Unlike standard release agents, it combines two functions: creating a release film to prevent sticking and simultaneously sealing the mold surface. This sealing action prevents air from being trapped and stops knit lines from forming, ensuring a perfect surface finish.

It is highly effective for natural rubber, EPDM, acrylic ester, and vinyl acrylate rubber. It is also specifically recommended for difficult-to-demold compounds such as fluororubber (FKM) and HNBR.

As a high-performance semi-permanent release agent, Lubekote 9165C is designed to provide multiple release cycles per application. The exact number depends on specific mold geometry, rubber compound, and curing conditions.

It is ready to use straight from the container. For some applications, particularly for achieving an ultra-thin film, it can be diluted with 1-3 parts deionized water.

The water-based formula contains no solvents or VOCs, making it safer for operators, better for the environment, reducing fire hazard, and helping factories meet strict regulatory standards.
