Corrosion Block

<h3>About Corrosion Block &amp; Lear Chemical Research</h3><p><strong>Corrosion Block</strong> is a flagship product line from Lear Chemical Research Corporation, a Canadian company with a well-earned reputation for developing some of the most effective anti-corrosion compounds available anywhere in the world. <a href="/14674-corrosion-block">Corrosion Block</a> products have been developed and refined since 1979, giving the brand decades of real-world experience solving corrosion problems across demanding industries including Automotive, Aviation, Industrial, Marine, Motorcycle, and Recreational sectors.</p><h3>Science-Backed Corrosion Protection</h3><p>What sets Corrosion Block apart is the chemistry behind it. The fluid actively protects metal through advanced polar bonding, where synthetic additives penetrate deep into existing corrosion cells, displacing salt water and allowing it to evaporate. What remains is a hydrophobic film that acts as a barrier, essentially shutting off the electrochemical processes that cause rust and corrosion to spread. This approach means Corrosion Block doesn&apos;t just mask corrosion — it actively addresses it at the source.</p><p>The product leaves no gummy residue because it contains no wax, resin, tar, asphalt, or silicone — making it a clean, clear solution that can be used on sensitive electrical components and precision mechanical parts alike. It is non-hazmat, non-flammable, and non-toxic, making it practical for professional and DIY use in virtually any environment.</p><h3>Trusted Across Industries</h3><p>Lear Chemical Research has built its reputation through rigorous laboratory testing combined with field evaluations to ensure every formula lives up to real-world demands. The ACF-50 product, a close sibling to Corrosion Block in the Lear Chemical lineup, gained widespread recognition after adoption by the U.S. Military and Coast Guard for corrosion prevention on aircraft. Meanwhile, Corrosion Block itself has become a staple in the marine-maintenance community across North America, where saltwater environments put metal components under constant attack.</p><p>From watercraft and jet skis to ATVs, fleet vehicles, snowmobiles, and industrial equipment, Corrosion Block products have expanded globally into virtually every sector where corrosion is a costly concern. The brand&apos;s product family — which includes Corrosion Block liquid, <a href="/14674-corrosion-block-marine-grease-18765">Corrosion Block Grease</a>, ACF-50, and Rust Block — gives technicians and enthusiasts a targeted solution for any application.</p><h3>The Corrosion Block Grease Advantage</h3><p>For applications requiring a heavier-duty barrier, <a href="/14674-corrosion-block-marine-grease-18765">Corrosion Block Grease</a> delivers maximum protection under severe conditions. Its formulation provides performance across both high and low temperature extremes, resists water wash-out, and outperforms conventional lithium greases. It meets or exceeds the NLGI GC-LB service classification — the benchmark standard for automotive wheel bearings and chassis lubricants — making it a versatile choice for marine, motorcycle, automotive, and industrial use alike.</p>

Product Details

Corrosion Block 20032 is a professional-grade corrosion prevention and treatment solution designed for marine, industrial, and automotive applications. This 32-ounce bottle comes with a convenient refill pump sprayer for easy application. The formula is non-hazardous, non-flammable, and non-toxic, making it safe for use in sensitive environments.

Advanced Protection Technology:

Corrosion Block uses advanced polar bonding chemistry to actively protect metal surfaces and electronics. The synthetic additives completely penetrate existing corrosion cells, displacing salt water and allowing it to evaporate. Once the corrosion is neutralized, a hydrophobic film remains on the surface, acting as an "off switch" for further corrosion. Unlike waxy competitors, Corrosion Block leaves a clean, clear, moisture-proof barrier that deeply penetrates joints, connectors, and fasteners.

Key Features:

  • Kills corrosion on contact, from fully submerged equipment to high-moisture environments
  • Advanced polar bonding chemistry actively protects metals and electronics
  • Penetrates corrosion cells and displaces salt water, allowing evaporation
  • Leaves hydrophobic protective film that prevents new corrosion formation
  • Non-toxic, non-flammable, and safe for use in critical safety applications
  • Trusted worldwide in mining, power generation, fuel depots, and refineries
  • Clean, clear finish without waxy residue

Ideal Applications:

  • Electrical switches, circuit breakers, and terminal strips
  • Battery terminals and alternator leads
  • Marine electronics, GPS systems, and running lights
  • Motor operated valves and pressure gauges
  • Fuse panels, connectors, and wiring harnesses
  • Fuel tanks, engines, and reefer unit wheels
  • Locks, hinges, and mechanical fasteners

The pump sprayer provides controlled, precise application for treating specific components or coating larger areas. Perfect for preventative maintenance or treating active corrosion problems on boats, vehicles, industrial equipment, and outdoor machinery.
