About Lear Chemical Research Corporation
Lear Chemical Research Corporation is a Canadian specialty chemical manufacturer with a singular, decades-long focus: solving corrosion. Lear Chemical Research has been successfully developing and compounding anti-corrosion lubricants and greases since 1979. What began as a mission to protect aircraft has grown into a globally trusted portfolio of products relied upon by professionals and enthusiasts across countless industries.
A Heritage Built on Fighting Corrosion
Founded in Canada in 1979, Lear Chemical Research is dedicated to developing world-class lubricants and anti-corrosion compounds. Through decades of rigorous research and testing, the company has established itself as a global leader in corrosion control solutions for highly demanding environments.
Lear Chemical's technical research-and-development success is balanced by combining laboratory-testing with specific field evaluations to ensure that each formula produced meets advertised claims and customer expectations. This commitment to verified, real-world performance is what sets Lear Chemical apart from competitors who rely solely on lab results.
Flagship Product Lines
Lear Chemical's commercially successful product lines include ACF-50, Corrosion Block, Corrosion Block Grease, and Rust Block — each engineered for a specific set of corrosion challenges.
- ACF-50 (Anti-Corrosion Formula): ACF-50's advanced corrosion control properties protect airframes, avionics systems, and ground support equipment. Its outstanding performance has been independently tested, verified, and trusted by the U.S. government and fleet operators around the world.
- Corrosion Block: Corrosion Block is an anti-corrosion compound developed exclusively to stop existing corrosion and prevent new. It is especially well-regarded in the marine maintenance community across North America.
- Corrosion Block Grease: A heavy-duty grease formulation designed for applications like watercraft trailers, wind turbines, and industrial machinery where sustained protection under mechanical stress is critical.
- Rust Block: Lear Chemical Research Corporation specializes in providing a range of corrosion-inhibiting products in both bulk and aerosol forms, aimed at preventing and controlling corrosion on metallic surfaces. Rust Block is among these targeted solutions for everyday rust prevention needs.
Industries Served
Lear Chemical Research develops and compounds anti-corrosion lubricants and greases — including ACF-50, Corrosion Block, Corrosion Block Grease, and Rust Block — effectively solving corrosion-related problems in the automotive, aviation, industrial, marine, motorcycle, and recreational industries.
From those core markets, the products have expanded globally and into other sectors such as motorcycles, firearms, watercraft trailers, emergency-service electrics, beach-based quad-bikes, and wind farms. Whether you're maintaining a daily driver against road salt, protecting a boat through a saltwater season, or keeping a powersports machine in top shape through the off-season, Lear Chemical has a solution engineered for your environment.
Custom Formulation Services
The company also offers custom formulation services, processing orders from small to large batches, and provides ready-to-ship custom formulations in bulk packaging. This makes Lear Chemical an ideal partner not just for individual consumers, but for fleet operators, OEM manufacturers, and maintenance facilities that require tailored chemical solutions at scale.
