SEM 69501, also known as Rust-Mort, is a high-performance, rust converter and inhibitor coating. This innovative product is specifically designed to convert existing rust on various surfaces into a stable, inert, and protective film. This film prevents further corrosion and rusting, thereby extending the life of the underlying metal.
The SEM 69501 coating is a two-component, water-based system. This means it consists of two separate components that must be mixed together before application. The first component is the rust converter, which actively reacts with the rust on the metal surface. The second component is the inhibitor, which forms the protective film once the converter has reacted with the rust.
The rust converter in SEM 69501 is based on a blend of complex chelating agents. These agents form stable, insoluble complexes with iron ions in the rust, effectively neutralizing them and preventing further oxidation. This process converts the rust into a stable, non-toxic, and water-insoluble compound.
The inhibitor in SEM 69501 is a blend of various organic compounds. These compounds form a tough, elastomeric film that provides excellent protection against water, oxygen, and other corrosive agents. The film also exhibits excellent adhesion to the converted rust surface, ensuring long-lasting protection.
SEM 69501 is suitable for use on a wide range of metal surfaces, including ferrous and non-ferrous metals. It can be applied to various substrates, such as steel, iron, aluminum, zinc, and copper. The coating can be used in various industries, including automotive, construction, industrial manufacturing, and marine applications.
The application of SEM 69501 is straightforward and can be done using various methods, including brushing, rolling, spraying, or dipping. The coating can be applied to clean, dry, and rusted surfaces. It is recommended to thoroughly clean the surface before application to ensure optimal adhesion and performance.
SEM 69501 offers several advantages over traditional rust-inhibiting primers. It is a water-based system, making it environmentally friendly and easy to apply. It does not contain any volatile organic compounds (VOCs), making it a more sustainable option. It is also a one-coat system, reducing the time and cost required for multiple coats.
In summary, SEM 69501, or Rust-Mort, is a high-performance, water-based, rust converter and inhibitor coating. It converts existing rust into a stable, protective film, preventing further corrosion and extending the life of the underlying metal. The coating is suitable for various metal surfaces and can be used in various industries. It offers several advantages over traditional rust-inhibiting primers, including being a one-coat system, environmentally friendly, and easy to apply.
