• It is suitable for industrial high performance coatings for wood, metal or plastics and fast drying industrial primers and topcoats.
• Recommended for topcoats for transportation, chemical maintenance or construction equipment and spot repair clearcoats for car refinishes.
• SETALUX® 17-1611 has a shelf life of 3 years.

EBECRYL® 436 by allnex is a reactive chlorinated polyester resin diluted 40% with the reactive diluent trimethylolpropane triacrylate (TMPTA). It exhibits good lithographic behavior, pigment wetting properties and fast cure response in ultraviolet light (UV) curable coatings and inks. Cured films of EBECRYL® 436 display good adhesion to metals, plastics and paper. It is recommended for wet lithographic inks for paper, plastics and metals, overprint varnishes and post-formable inks.

EBECRYL® 600 by allnex is a low VOC diacrylate ester of bisphenol A epoxy resin. It provides light color and fast cure response.

• Films cured via exposure to ultraviolet light (UV) or electron beam (EB) possesses high surface hardness and gloss and excellent chemical resistance.
• It reduces energy consumption and exhibits low carbon foot print, good compatibility, low flammability and long potlife.
• It is a radiation curable, solvent- and tin free grade.
• EBECRYL® 600 is recommended for lithographic and screen inks, overprint varnishes and fast cure coatings.
• It is also used in coatings for paper, paperboard, wood, chipboard and rigid plastics.

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).

THIXATROL® ST by Elementis acts as a rheological additive for use in aliphatic and aromatic solvent-based coatings. It is an organically modified castor oil derivative. It provides increased viscosity, thixotropy, pigment suspension and sag control. It improves the flow and leveling of powder coatings. It is suitable for chlorinated rubber- and decorative coatings, traffic- and anti-fouling paints.

• It offers controlled penetration into porous substrates and imparts excellent package stability and reproducibility.
• It shows no adverse effect on paint durability and no influence on water-resistance of organic systems.
• It is non-yellowing in the final formulation and does not normally react with system components.
• THIXATROL® ST is used in epoxies, polyurethanes, varnishes, air dry industrial-, high build- and hammer finishes.
• The recommended dosage level is 0.2-0.8% by weight.
• It has a shelf life of 4 years.
