BEST CORROSION RESISTANT MOUNTING PLATES

Permatex Marine Grade Anti-Seize

Permatex
🏠 Local Product

Permatex Marine Grade Anti-Seize is a specialized lubricant that prevents galvanic corrosion, galling, and seizure of bolts and studs used in bicycle carrier mounting hardware, making it a vital complement to any sealant system. As a preventive, it is highly cost-effective—much cheaper than replacing corroded hardware—and technically more appropriate for threaded connections than typical sealants because it preserves serviceability. Used alongside a waterproof sealant (silicone, polyurethane or epoxy), Permatex ensures fasteners remain removable and corrosion-free in saltwater environments.

What Research and Standards Say About Corrosion-Resistant Hardware and Coatings

The benefits of corrosion-resistant hardware and high-performance coatings are supported by a combination of laboratory testing, field trials, and lifecycle assessments. Independent test standards and industry guidance help predict real-world durability, while engineering studies show how material choice and coating system selection reduce long-term maintenance costs and failure risk. For American applications, studies and standards emphasize salt spray resistance, adhesion and thickness of protective layers, compatibility to avoid galvanic corrosion, and the importance of surface preparation.

Salt spray and cyclic corrosion testing: Standards such as ASTM B117 and ISO 9227 are widely used to evaluate coating resistance to chloride-rich environments. Higher hours in salt spray tests generally correlate with longer service life in marine and roadside exposure.

Lifecycle and total cost analyses: Industry life-cycle studies indicate that investing in corrosion-resistant materials and coatings often reduces total ownership cost by lowering repair and replacement frequency, especially in harsh winter or coastal climates.

Galvanic compatibility and material pairing: Corrosion science and NACE/AMPP guidance highlight that improper mixing of dissimilar metals can accelerate corrosion; properly chosen insulating coatings or compatible material pairings minimize galvanic risk.

Performance of anodized aluminum: Peer-reviewed studies and manufacturer data show that anodizing increases aluminum's surface hardness and improves resistance to pitting and general corrosion, making it well suited for coastal installations when properly sealed.

Powder coatings and industrial topcoats: Research on powder-coated systems and high-performance polyurethanes or epoxies demonstrates strong adhesion, UV resistance, and moisture barrier properties when applied over properly prepared substrates.

Standards and certification: Compliance with CSA, ASTM, NACE/AMPP, and marine-coating manufacturer technical data sheets provides measurable benchmarks for specifying products for American municipal and industrial projects.

In the American context, choosing the right combination of stainless, galvanized, powder-coated, or anodized mounting hardware and marine-grade coatings can significantly extend service life and reduce maintenance in coastal and winter salt-exposed locations. We hope this guide helped you find the right options for your project.
