TINSCO Flash Rust Corrosion Inhibitors

Flash rust can occur in the early stages of application and drying of water based coatings on metal surfaces. Corrosion migrates through the coating and manifests itself on the surface of the coating, in the form of spots, staining or mottling. Welded surfaces can be particularly prone to flash rust.

Water borne coatings have the two primary requirements to allow corrosion; oxygen and water.

Direct to metal (DTM) water borne coatings are typically applied in a thin film. This allows oxygen to readily permeate through the coating, and therefore, flash rusting is a common problem.

Why use flash rust inhibitors?

  • Drive to reduce VOC content of coatings in recent years is partially responsible for driving the growth of waterborne technologies
  • This makes high-performance anti flash-rust additives of particular interest.

Flash Rust Inhibitors offer immediate, short-term protection by blocking oxidation at the surface. The nitrite FREE, liquid TINSCO flash rust inhibitors can be added, during manufacturing or post-mix, to effectively suppress the early effects of corrosion during the drying process.

Why Nitrite FREE?

  • Nitrites can be used to inhibit the effects of flash rusting in water based coatings.
  • A key component of many water based coatings are Amines. These are widely used in to control the pH required for good stability and product performance.
  • Nitrites and Amines can react to result in the formation of Nitrosamines, which may increase the risk of cancer if people are exposed to them above acceptable levels and over long periods of time.
  • Because of this, all TINSCO products are Nitrite FREE.
