McLube offers a full line of conventional mold release agents for small sprue openings, cavities, parting lines, and deep drawls where semi-permanent coatings may not be effective. Our conventional (sacrificial) mold release agents are designed for frequent application (before each cycle) to the most difficult to release, difficult to coat areas of complex molds with custom slip characteristics to ensure easy release and no undue buildup. We offer water and solvent-based conventional release options with custom dilutions to suit the individual needs of every customer. McLube’s conventional release technology can also be used to extend the life of permanent, in-mold coatings like nickle, Teflon®, and anodized surfaces. We currently offer siliconesilicone-free, and PTFE-based conventional release agents that can be diluted in-house or delivered ready-to-use. Contact us and a McLube Technical Representative will help you decide if a conventional mold release agent would be ideal for your molding operation.

Benefits of McLube

 

Conventional

 

Mold Release Agents

Excellent flow and slip characteristics, low buildup

Custom degrees of slip to suit individual needs

Ideal for spray application in difficult-to-reach areas

Extend the lifespan of permanent, in-mold coatings

General-purpose release useful around the entire plant

Supported Materials

While plastics, urethanes, and composite materials are ideal candidates for semi-permanent coatings, some rubber molding operations still require the unparalleled flow characteristics of conventional coatings for difficult to release areas. McLube conventional mold release agents are ideal for release of all natural and synthetic rubber compounds, including notoriously tacky materials like FKM and nitriles.  Visit our rubber mold release agents page to learn more about McLube Release Technology for rubber molders.

Conventional (sacrificial) vs. Semi-permanent

Most conventional (sacrificial) mold release agents are non-functioning silicones, waxes, or oils that create a physical barrier between mold and material that is transferred to and removed with the molded part. A non-functioning coating does not bond to itself or the mold surface. Semi-permanent release technology was developed with functioning, crosslinking additives to increase the durability of the release coating and allow for multiple releases per application. Unfortunately, semi-permanent release agents do not possess the flow characteristics to reach certain drawls, cavities, and sprue openings seen on some complex rubber molding surfaces. Conventional/sacrificial coatings, while based on older release technology, possess the flow characteristics to reach difficult to release areas.

 

McLube conventional mold release agents have been specifically formulated for easy spray, wipe, or brush application and will effectively transfer to the molded part to prevent buildup and extra cleaning steps in hard-to-reach areas. If you are applying a semi-permanent-type release agent more than four times in an hour, then you may want to try a dilute conventional mold release. Contact McLube and an experienced technical representative will help you select the ideal conventional mold release agent for your operation.

Custom slip characteristics

Every customer’s process is different and McLube believes that superior results come from tailored release technology rather than generalized formulations. McLube Technical Representatives and Formulation Chemists will work with your production staff to formulate a tailored dilution with the optimal degree of slip and flow characteristics for your operation.
