Lord Corp. Launches New Family of Fast-Curing Release Agents for Molded Elastomers

Lord Corporation has announced the availability of a proven family of fast-curing release agents designed for use with molded elastomers.

Lord LokRelease Mold Release solutions are formulated to increase time between mold-picking and to reduce mold fouling in the rubber-to-substrate molding processes.

“Now commercially available, our mold releases have been used in Lord rubber-to-metal part manufacturing facilities for several years,” says Chris Schneider, Manager, Tech Services, Lord Corporation. “Building on more than 90 years of experience with world-leading in-mold bonding adhesives, Lord LokRelease solutions provide a semi-permanent, anti-stick surface coating for fast, easy part removal from molds.”

Applications for Lord LokRelease Mold Release include industrial rubber-to-substrate molding, automotive rubber-to-substrate molding and other molding processes such as injection, compression and transfer molding.

Advantages of the Lord LokRelease Mold Release solutions include the following:

• Versatility–LokRelease is available in three convenient product forms of aerosol, aqueous and solvent-based solutions.
• Process Enhancer–Provides quick, easy part release and produces low build-up, allowing more production time between mold cleanings.
• Manufacturing Efficiencies–A single application allows for multiple molding cycles.
• Improved Appearance–Reduces defects caused by sticking and is nontransferable, eliminating post-finishing problems.
• Environmentally Recommended–Contains no Class I or Class II ozone-depleting substances; contains no 1, 1, 1, tricholoroethane or methylene chloride. A water-based coating reduces rust and corrosion in steel molds.

Substrates compatible with Lord LokRelease include the following:

• EPDM
• Natural rubber
• Nitrile
• Neoprene
• Epoxy/plastic laminates
• Silicone
• Fluoropolymer
• Plastic

“This family of mold release solutions makes part release from the mold quick and easy,” says Schneider. “Just a single application allows for multiple molding cycles. LokRelease also reduces defects caused by sticking, does not transfer to the elastomer compound and doesn’t interfere with compound chemistry.”
