Blockade™ GC, Corrosion Resistant Fasteners

Luna Labs has developed an innovative product called Blockade GC, a groundbreaking chromate-free corrosion control coating specifically designed for aircraft fasteners and rivets. However, its corrosion mitigation capabilities extend beyond aviation and can be applied to various industries facing similar challenges. This exceptional coating acts as a durable and thin barrier, effectively mitigating galvanic corrosion around fasteners, bushings, and other dissimilar metallic interfaces.

Blockade GC stands out from competitors due to its unique ability to block the electrical current that triggers corrosion, effectively addressing the root cause of the problem. By preventing galvanic coupling between components, this revolutionary coating not only impedes the development of corrosion but also significantly enhances durability and overall performance. It is an eco-friendly and cost-effective solution that can be easily applied during factory production or by a skilled applicator, eliminating the need for additional installation steps.

Damage (represented here by charge in Coulombs) was reduced by >80% with Blockade GC (sol-gel) coated fasteners.

The below plot shows the corrosion damage, depicted in charge, of various bare and Blockade™ GC coated fasteners mated to coated 7075-T6 aluminum plates. Even when the fastener holes had scribes through the paint down to bare aluminum, the Blockade™ GC coating resulted in substantial reduction in aluminum galvanic corrosion damage (i.e. charge), and in some cases a reduction by as much as > 80%. Blockade™ GC provides consistent and predictable corrosion control, with performance greater than or equal to more costly materials.
