Anticorrosion Layer and Process for Production Thereof

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention provides an advanced anticorrosion layer and its fabrication process, particularly suited for protecting metals such as steel from both classical corrosion and microbially induced corrosion (MIC). The layer is mainly formed from crosslinked, pre-condensed alkoxysilane precursors, resulting in a dense, defect-free protective coating of at least 50 µm thickness. The solution can be applied via conventional methods (brushing, spraying, dipping), cures by heat or chemical means, and is formulated without toxic or environmentally harmful additives like heavy metals or organic solvents. The system is also compatible with integration of beneficial microorganisms and customization for additional protective or functional properties.

Use CasesContent extracted from patent full text and abstract with AI.

• Protecting steel structures (e.g., bridges, buildings, pipelines) from atmospheric and water-induced corrosion.
• Marine industry: coating ship hulls, offshore platforms, and underwater components to prevent corrosion and fouling.
• Infrastructure: coating rebar or steel frameworks in concrete to enhance longevity.
• Protective coatings for metal tanks, pipes, and machinery in chemical, oil & gas, or water treatment plants.
• Automotive and aerospace industry: coating vehicle bodies, exposed parts, or components for improved durability.
• Electronics: using the coating as an insulating and transparent protective layer on delicate metallic electronic parts.
• Preserving art, heritage items, or metallic sculpture by providing a clear, non-intrusive barrier against environmental degradation.

BenefitsContent extracted from patent full text and abstract with AI.

• Excellent corrosion resistance, including protection against microbially induced corrosion (MIC).
• Does not rely on toxic additives (e.g., tin or copper), making it more environmentally friendly and compliant with regulations limiting hazardous substances.
• Solvent-free formulation reduces volatile organic compound (VOC) emissions and environmental hazards.
• High chemical and mechanical resistance, with customizable thickness and the option for further property enhancements (e.g., scratch resistance, chemical barrier).
• Easy application by multiple established coating methods; good adhesion without a primer.
• Transparent and smooth finish allows for use as a clear coat that does not obscure substrate appearance.
• Can be combined with porous layers or bacteria-hosting layers to provide active, long-term resistance against microbial corrosion.
• Cost-effective due to simple formulation and use of widely available starting materials.
• Stable during storage and after application; flexible curing options (thermal or chemical) suit a range of industrial processes.

Patent Abstract

The invention relates to a protection layer which is used as anticorrosion layer on corrosion-prone substrates, especially corroding metals, alloys and other materials, especially on steel, and as a basecoat for the application of further porous layer systems or as a topcoat, and to the process for production thereof and to use on a coated substrate for protection against corrosion and specifically for use against microbially induced corrosion (MIC), wherein the anticorrosion layer comprises a high-density protection layer on a corrosion-prone substrate, containing pre-condensed layer-forming alkoxysilane precursors, wherein the molecules of the pre-condensed layer-forming alkoxysilane precursors are formed from monomer units selected from the group of the triethoxysilane precursors, wherein the molecules of the pre-condensed layer-forming alkoxysilane precursors are crosslinked with one another, and wherein the high-density protection layer has a layer thickness of at least 50 μm.
