Multi-Purpose Corrosion Protection, Electrically Safe

The SKF KA74004-4 (Krown KL73) is a multi-purpose corrosion preventative lubricant aerosol manufactured in Canada for professional fleet and industrial service. Rated at 50 kV dielectric strength, it can be applied on and around electrical components and wiring without creating conductive paths. The solvent-free, non-toxic, biodegradable formulation actively displaces moisture, forming a protective film that inhibits rust even after exposure to washdowns, road spray, or humid environments. Designed for heavy-duty vehicles, off-highway equipment, and plant assets, it offers broad compatibility for routine maintenance and storage. Food-grade approval throughout North America broadens applicability in facilities where incidental food contact compliance is required.

Performance for Fleet and Industrial Maintenance

Use KA74004-4 to protect frames, fasteners, battery terminals, connectors, and exposed assemblies during routine maintenance or seasonal rust-proofing. Apply after steam cleaning or power washing to protect against flash rust. Its moisture-displacing action helps prevent corrosion initiation on wet surfaces, while the durable film reduces reapplication frequency after washing or road-salt operations. The aerosol delivery enables fast penetration into seams and crevices, supporting efficient coverage in the shop or in the field. By limiting corrosion at interfaces, it helps maintain serviceability of fasteners and connectors and supports planned maintenance schedules.
