Composite Release Agents

We are here to help achieve your process goals.

McLube® offers a full line of water and solvent-based mold primers, external release agents, and cleaners tailored to aerospace, automotive, marine, construction, and recreational composites manufacturing. We offer composite release systems for a variety of matrices, including epoxies, phenolics, vinyl esters, and polyesters as well as custom formulations for unique blends used in cutting-edge advanced composites.

As the world looks to the composites industry more and more, we have focused on developing coatings which not only help our customers produce excellent parts but also reduce labor and time-to-produce. We want to help our customers make more composite parts viable alternatives to traditional materials while also improving sustainability and your bottom line. We are focused on less material consumption, faster cure times, fewer coats, and better tooling protection – our goal is to unlock the most value for our customers as possible.

Our dedicated technical representatives around the world stand ready to help you achieve your most complex process goals. Contact us today, and we will get to work for you.

Featured Products

Product	Description
McLube® 818	A water-soluble emulsion designed to ensure long-lasting durability and provide sufficient slip for effortless release from tooling. Provides a tailorable degree of slip and may be easily washed from the part after molding. Recommended For: vacuum bagging/ layup Operating Temperature: Up to 600°F (316°C)
McLube® 1039	Forms a thin film to preserve tooling details and allow for easy part removal without risk of prerelease. Outperforms PVA coatings in terms of detail preservation and is less labor intensive than wax-based coatings. Provides extended rust and corrosion prevention for metallic molds in storage. For some applications, this product eliminates the need for a priming or sealing step. Recommended For: Epoxy-bound composites, urethanes, mold protection Operating Temperature: Up to 700°F (371°C)
McLube® 1733H	A solvent-based dispersion of polymers and resins that cures in seconds. Recommended For: Mandrel-build composites/ filament winding and layup operations using phenolic matrices Operating Temperature: Up to 550°F (288°C)
McLube® 3072	A fast-drying, solvent-based release agent recommended for carbon fiber and composite armor applications. Designed to withstand high curing temperatures.
McLube® Composite Mold Primers	Designed to seal worn or previously cleaned molds to eliminate microporosity. Promotes high-quality, gloss finish. Class A finish is achievable and may or may not require additional buffing of the coating. A maximum of 2-3 coatings is sufficient thus reducing material consumption. High resistance to increased temperature and chemical degradation. A release agent should be applied over this coating to ease part removal.

Performance

Reduced Buildup and Mold Protection

Our composite release agents are designed to provide reliable release characteristics without building up on the mold surface. Reduced buildup will cut down on cleaning time and frequency as well as reduce rejection rates due to poor surface finish or failed release. Reducing the frequency of cleaning operations also saves molds and tools from physical and chemical abrasion over time extending their effective lifespan.
