CR-3600
Heavy-Duty Biobased Protection for Your Equipment & Infrastructure
CR-3600 is BioSpan’s high-performance corrosion inhibitor engineered to protect exposed metal surfaces in the harshest environments. Ideal for use on construction equipment, metal structures, and critical machinery, CR-3600 is made from sustainable biobased ingredients, offering long-lasting protection without the environmental or safety hazards of traditional petroleum-based products.
Why CR-3600?
Biobased & Biodegradable – Made with renewable ingredients that meet USDA BioPreferred standards.
Heavy-Duty Rust Protection – Forms a durable, protective barrier on metal surfaces.
VOC-Free & Non-Toxic – Safe to apply in enclosed or sensitive environments.
Resists Wash-Off – Water-repellent and weather-resistant for long-term outdoor use.
Safe on Paint, Wiring & Seals – Will not damage equipment coatings or components.
Applications
CR-3600 is ideal for:
• Asphalt & construction equipment
• Tools, rollers, drag slats, and hoppers
• Metal doors, fencing, and railings
• Vehicle undercarriages
• Salt-exposed infrastructure (e.g. bridges, docks, trailers)
• Seasonal equipment storage (mowers, pavers, loaders)
How to Use CR-3600
Apply to clean, dry surface
For best results, remove any loose rust or debris.
Spray, brush, or dip
CR-3600 can be applied manually or with automated systems.
Allow to cure
CR-3600 can be applied manually or with automated systems.
CR-3600 can also be used as a forms release agent for wood, metal, or fiberglass forms.
It is especially effective in preventing corrosion during storage after exposed to corrosive salts. May be used to protect and extend the life of radiator cores and cooling fins on heavy load trucks, as well as concrete saws and mud jacking equipment exposed to water and other wet surfaces.
