Technology Features & Specifications
In addition to being chromate-free and hence safer and compliant with the latest industry regulations, the unique technology from this company also provides advanced corrosion control through its smart ‘on demand' technology, where anti-corrosion inhibitors are released from the coating as and when it is needed, for example, when following surface damage such as a cut edge or scribe. This is enabled through an intelligent micro/nano reservoir system containing inhibiting pigments that are able to sense and react to environmental changes and other corrosion-related activities. When a change is detected, aggressive corrosive ions are sequestered to the reservoir to prevent the onset of corrosion while highly effective inhibitors are released to further protect the coating. The new system thus allows coatings to protect end products for a longer time and more effectively. Under laboratory conditions, the technology has outperformed hexavalent chromate and has also been tested to be 10 times more effective than other chromate-free alternatives.
Compatible with existing systems, the coating may also be applied to a metal substrate as part of a coating system, such as a primer, where other materials or additives may be provided in the coating or additional coating layers may be applied to the substrate.
The smart release anti-corrosion technology may be used in the formulation of new coating applications in the aerospace and aircraft, marine, construction, automotive and transport sectors or be a substitute to current environmentally unacceptable surface coatings. It may also be potentially applied to other sectors or industries where environmentally preferred corrosion inhibitors are required.
The technology has been found to outperform current market leading alternatives on mild steel, alloyed steel and others, with the majority of feedback showing best compatibility within solventborne systems or non-ionic waterborne systems.
Outperforming both hexavalent chromate and current chromate-free alternatives in laboratory testings and independent testing by industry partners respectively, the smart release technology offers:
- A safer, more economical and effective alternative
- Reduced costs for protecting against, inspecting for, and repairing corrosion
- A longer lifetime cycle of the end product
- Compliance with the long-term corrosion regulation requirements of the industry
- Compatibility with existing coatings systems – i.e. as a sacrificial coating such as zinc or zinc alloy on galvanised steel, providing improved corrosion resistance to the underlying steel
