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).

SYLOID® C 809 distributed by DKSH is a high porosity, synthetic amorphous silica-based matting agent of medium particle size. It exhibits high matting effect, favorable gloss/ sheen ratio, outstanding incorporation and dispersion behavior and excellent overgrind resistance.

• It is suitable for use in coil coatings, general industrial coatings and decorative & trade sales paints.
• SYLOID® C 809 has a shelf life of 12 months.
• It is available in Europe.

Bentone® 34 by Elementis acts as a rheological additive designed for low to intermediate polarity organic systems. It is an organic derivative of a bentonite clay. It prevents pigment settling during storage and syneresis in thixotropic systems.

• It improves flow and leveling and controls sagging on vertical surfaces and penetration on porous substrates.
• It increases viscosity and provides thixotropy.
• It is used for anti-corrosive paints, automotive finishes, coil coating systems, dip coatings and industrial finishes.
• Also used in interior and exterior house paints including do-it-yourself paints, paint stripper pastes, printing inks, refinishes for household appliances and road marking paints.
• Recommended dosage level is 0.2-0.5% for house and industrial paints, 0.5-1% for primer and 0.2-0.3 for aqueous systems.
• Bentone® 34 has a shelf life of 4 years.

• It is formulated to meet air pollution regulations.
• It imparts excellent balance of hardness and flexibility.
• It produces high-gloss films with excellent color and color retention.
• ETERKYD 4901-B-72 is recommended for coil coatings, general industrial gloss bake enamels for spray, dip, or flow.
• It is suitable for high-solids, solvent-thinned coil coatings, can coatings and waterborne one-coat systems.
• This product is available in Canada and USA.

SYLOID® 622 distributed by DKSH is a synthetic amorphous silica. It is an untreated medium porosity silica matting agent of coarse particle size. It acts as non-slip/anti-skid additive in coil coatings.

• It is used in thick film coatings, powder coatings and radiation curable systems.
• It has a shelf life of 12 months.
• SYLOID® 622 is available in New Zealand, Australia and Europe.

MARNEX™ AH651 by Macroocean is a high molecular weight, saturated linear polyester resin. It shows excellent adhesive strength to steel and PET or PVC films. It offers heat seal properties, excellent pigment wetting and heat resistance. Also, offers better flexibility and adhesion is available while using with low Tg types of resin, such as MARNEX™ AL171 and MARNEX™ AL072. It can be dissolved in ketone, ether or esters type of solvents, such as isophorone, acetone, MEK, CYC, DBE & EA. And it is usually dissolved with aromatic solvents, such as 100# & 150#.
