Corrosion Inhibitors for Coatings and Inks

HALOX® 680 by ICL is a VOC-free, non-flammable, smart release anticorrosive pigment which releases a heterocyclic organic corrosion inhibitor from an organic matrix that adsorbs on the metal surface and forms a protective film.

• It is suitable for solvent-based primers & DTM alkyds, acrylics, water-based epoxies and urethanes, high solids and 100% solids, semi-gloss paints and coil coatings.
• The dosage level of HALOX® 680 as a stand-alone corrosion inhibitor or as an adhesion promoter is 1-2% based on total formula weight (TFW).
• When used in synergy with standard zinc phosphate the loading level of the product is typically 0.5-4% on total formula weight (TFW).

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.

HALOX® SZP-391 by ICL is a non-refractive, most efficient and versatile corrosion inhibiting pigment designed for long-term corrosion protection of coatings systems. It is a blend of strontium and zinc phosphosilicates. It is recommended for solvent-based epoxies, epoxy esters, polyurethanes, short-, medium- & long oil alkyds (both traditional and high solids), polyesters and silicones.

• It is suitable for water-based epoxies, polyurethanes, polyurethane dispersions, water-reducible alkyds, alkyd dispersions, chlorinated polymers and acrylics.
• It is designed for use in high acid value resins, latexes, catalyzed baking systems and vinylidene chloride latexes.
• The fine particle size and low oil absorption of HALOX® SZP-391 makes it the pigment of choice in thin film applications (<1 mil or 25 microns).
• The dosage level is 2-5% based on total formula weight in many water-based systems and 3-7% based on total formula weight in traditional solvent-based coatings.
• It has a shelf life of 36 months.

HALOX® Z-PLEX 111 by ICL is a highly versatile and economical corrosion inhibiting pigment. It is zinc phosphate complex designed to compete head-to-head with standard zinc phosphate pigments. It is a white, non-refractive grade used in protective coating systems.

• It is suitable for solvent-based epoxies, epoxy esters, short-, medium- & long oil alkyds and water-based epoxies, polyurethanes & polyurethane dispersions.
• HALOX® Z-PLEX 111 has a shelf life of 36 months.

HALOX® SZP-395 by ICL is a white, non-refractive, efficient and versatile corrosion inhibiting pigment designed for protective coating systems. It is a proprietary blend of strontium and zinc phosphosilicates.

• It is recommended for use in a wide variety of resin systems such as alkyds (both traditional and high solids), epoxies, latexes, water-reducible alkyds, high acid value resins, catalyzed baking systems, and vinylidene chloride latexes.
• The fine particle size and low oil absorption of HALOX® SZP-395 makes it the pigment of choice in thin-film applications (<1 mil or 25 µm).
• The dosage level is 2-5% for water-based systems and 3-7% for solvent-based coatings based on total formula weight.
• It has a shelf life of 36 months.

Nalzin® FA 179 by Elementis is a corrosion inhibitor for aqueous paint systems to counteract the formation of flash-rust. It is also suitable for application as an inhibitor against the formation of in-can corrosion and temporary rust inhibitor for metal surfaces.

• It can be applied to various types of water-dilutable alkyd systems, acrylics, epoxy and dispersion paints.
• The typical use level is 0.1-0.5% calculated on the total amount of paint.
• Nalzin® FA 179 has a shelf life of 3 years from the date of manufacture.

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.
