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 offers decreased cathodic delamination (undercutting) and improves cut edge protection.

• It is jet milled grade that provides increased intercoat coating adhesion and prevents osmotic blistering. It reduces cost by lowering zinc phosphate loading.
• It acts synergistically with other corrosion inhibitors such as zinc phosphate, Z-PLEX 111, SZP-391, HALOX® 430 and Zn-free phosphates.
• It can be formulated into solvent-based, high solid-, and powder coatings.
• 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).

SHIELDEX® AC 5 distributed by DKSH is an easily dispersible, non-toxic, high performance anti-corrosive pigment. It is a synthetic, calcium ion-exchanged amorphous silica.

• It is suitable for use in water-borne general industrial coatings, maintenance and protective coatings and automotive paints.
• SHIELDEX® AC 5 has a shelf life of 18 months.
• It is available in Europe.

• It is micronized particle of controlled particle size distribution.
• It is not classified as toxic and contain only technically unavoidable traces of heavy metals originating from raw materials.
• It highly effective due to their structural design and can be used in a wide variety of resin systems.
• SHIELDEX® C 500 is suitable for coil and metal coating application.
• Recommended usage level is 2-10%.
• It is available in Europe.

SHIELDEX® AC 3 distributed by DKSH is an easily dispersible, non-toxic, high performance, anti-corrosive pigment with low particle size. It is calcium ion-exchanged, synthetic amorphous silica. It is suitable for use in coil coating- and one- or two-component wash primers.

• SHIELDEX® AC 3 has a shelf life of 12 months.
• It is available in Europe.

Z-952 distributed by DKSH is zinc chromate yellow, inorganic- and anti-corrosive pigment. It is designed for solvent-based paint systems including alkyds & epoxy-polyamide primers. Z-952 is available in Asia and North America.

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-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® 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.

HEUCOPHOS® ZPA by Sudarshan Chemical Industries is an active multi-level anti-corrosive pigment with improved pigment structure, particle size distribution and dispersibility. It is based on zinc aluminum orthophosphate hydrate.

• It possesses increased water-soluble amount resulting in a better supply of inhibitive ions over a long time.
• It exhibits a higher performance efficiency in comparison to conventional zinc phosphates.
• HEUCOPHOS® ZPA is recommended for coil coatings, direct to metal (DTM) coatings, powder coatings and UV cured systems.
• It is suitable for solvent-based coatings based on long-, short- & medium oil alkyds, high solids alkyds (with low or no VOC), high solids- & 2K epoxies, epoxy esters, silicone resins as well as 2K-, high solids- and moisture-cured polyurethanes.
• It is also used in water-based coatings based on alkyd emulsions, 2K epoxies, 2K polyurethanes, silicone resins as well as acrylic & modified acrylics, and butadiens (with low or no VOC).
