HALOX® FLASH-X® 152 by ICL is an ultra-low-VOC flash rust inhibitor based on anodic passivating oxyanion. It is effective in preventing general flash rusting and weld seam corrosion. It is highly effective at relatively low loading levels as compared to other high and low VOC flash rust inhibitors.

• It is compatible with a variety of water-based resins without causing film sensitivity or package stability problems which can occur with other flash rust additives.
• It is heavy metal-, APEO-, and HAPS free.
• HALOX® FLASH-X® 152 is designed for industrial and architectural paints.
• Recommended dosage level is 0.5-1.5% to stop flash rust and 1.0-2% to stop galvanic corrosion.

Nalzin® FA 180 by Elementis is a flash-rust corrosion inhibitor designed for aqueous paint systems. It prevents the formation of flash rust during the drying process on iron-containing substrates. It is based on an organic zinc complex with a low nitrite addition.

• It exhibits a strong affinity for iron substrates, forming a protective anionic passivated layer after drying.
• It provides corrosion resistance and improved weathering properties.
• During the drying process, it transforms from a water-dispersible form into a non-water-dispersible, insoluble zinc compound and reducing water sensitivity.
• It is suitable for various water-dilutable paint systems such as alkyds, acrylics, epoxies, and dispersion paints.
• It enhances the rust resistance of the dried paint layer and acts as an in-can corrosion inhibitor during storage.
• Additionally, it can be used as a temporary rust inhibitor for metal surfaces when applied as a 2% emulsion through spraying, offering reliable protection against early rust formation after paint application.
• Recommended dosage level is 0.1-0.5% as flash-rust inhibitor and 0.1-0.3% as in-can corrosion inhibitor.
• Nalzin® FA 180 has a shelf life of 2 years from date of manufacturing.

HALOX® FLASH-X® 330 by ICL is an effective, nitrite-free, low odor, liquid flash rust inhibitor. It is used in the manufacturing of water-based protective coatings for inhibition of in-can rusting for unlined metal containers. It is recommended for high gloss systems and does not detract from gloss.

• It is added to water jet-blasting solutions to provide temporary protection prior to applying the protective coating.
• HALOX® FLASH-X® 330 is easy to use and can be incorporated at any stage of coating manufacture.
• It can also be easily and effectively post added to any coating system.
• The dosage level for flash-rusting application is 0.5-2% and for in-can rusting is 1.5-2.5%.
• It has a shelf life of 24 months.

LOPON® DV by ICL is a flash rust corrosion inhibitor-based on disodium phosphate. It is an aqueous solution that can be used in water-based emulsion paints. It is suitable for exterior wall paints.

• LOPON® DV is recommended for premium plasters, renders, and other aqueous building products.
• It has a shelf life of 3 years.

Flexisperse™ CW-40 by Innovative Chemical Technologies is a unique functionalized polymer system designed to impart a clear, colorless, readily removable, surface protectant and soil resistant coating. Provides flash rust and corrosion resistance to bare copper, steel, brass, cadmium and zinc. It provides temporary protective surface coating which withstands weathering effects such as acid rain and salt water. The hard film coating also provides protection against abrasive impacts from particulate matter. It imparts gloss to a surface but adds no color or haziness. The coating can be removed with 1:64-1:32 aqueous dilution of Flexiclean CWR cleaner or other alkaline cleaner concentrate. It is recommended for construction & rental equipment, automotive OEM protection during transit and metal stock in storage, transit or work-in-progress. Flexisperse™ CW-40 has a shelf life of 12 months.

HEUCOFLASH™ LQ2 by Sudarshan Chemical Industries is a nitrite- & VOC-free, highly effective liquid flash rust inhibitor. It is a solution of organic & inorganic compounds and salts.

• It offers early protection by preventing the formation of rust spots during the gelling & curing time, while maintaining its positive long term effect.
• HEUCOFLASH™ LQ2 is suitable for all kind of waterborne protective coatings, metal treatment and packaging protection.

HEUCOFLASH™ LQ1 by Sudarshan Chemical Industries is a VOC-free, nitrite-containing, highly effective liquid flash rust inhibitor. It is a solution of organic and inorganic salts.

• It provides early protection by preventing the formation of rust spots during the gelling and curing time, while maintaining its positive long term effect.
• HEUCOFLASH™ LQ1 is suitable for all kind of waterborne protective coatings, metal treatment and packaging protection.

HALOX® 350 by ICL is a more active 97-100% solids organic corrosion inhibitor designed to stop flash rust, and in-can corrosion, and provide temporary corrosion protection. It is an effective replacement for toxic nitrite-based flash rust inhibitors.

• It has a recommended dosage level is 0.2-0.8% based on total solids formulation.
• It has a shelf life of 36 months.
