WANNATE® HB-75MX by Wanhua Chemical is an aliphatic biuret polyisocyanate based on hexamethylene diisocyanate (HDI) and dissolved in 25% of 1-methoxy-2-propyl acetate (MPA) and xylene (1:1). It exhibits high chemical- and weathering resistance, very good gloss retention and outstanding mechanical properties. It can be mixed with aliphatic- and aromatic polyisocyanates, polyester polyols and polyacrylates.

• It can be used as the hardener component for lightfast two-component polyurethane coatings.
• WANNATE® HB-75MX is suitable for automotive refinishing, transportation, industrial finishing and plastic coatings.

CASAMID® 1416 by Thomas Swan acts as a gloss reducing curing agent and reactive matting agent. It is designed for use in interior coatings as well as black & dark shade epoxy- & hybrid powder coatings.

• It offers good flow and surface smoothness to the coatings.
• Epoxy coatings with gloss levels ranging from 5-15% and hybrid coatings with gloss levels ranging from 15-60% (or greater) can be easily formulated using CASAMID® 1416.
• The recommended dosage level is 8-12 phr.
• It has a shelf life of 12 months.

SHIELDEX® C 303 distributed by DKSH is an easily dispersible, non-toxic, high performance anti-corrosion pigment of relatively low particle size. It is a calcium ion-exchanged, synthetic amorphous silica. It is used in coil coating primers, reactive primer systems and powder coatings.

• SHIELDEX® C 303 has a shelf life of 12 months.
• It is available in Europe.

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.

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.

WANNATE® HT-100 by Wanhua Chemical is a solvent-free, aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI). It can be used as the hardener component for lightfast two-component polyurethane coatings. It offers high resistance to chemicals and weathering, very good gloss retention and outstanding mechanical properties.

• WANNATE® HT-100 is suitable for automotive refinishing, transportation, industrial finishing and plastic coatings.
• It can be mixed with aliphatic- and aromatic polyisocyanates, polyester polyols and polyacrylates.

Omyacoat 420 by Omya is an ultrafine, calcium carbonate-based, functional mineral filler. It is designed for solvent-based decorative paints, gloss powder coatings as well as industrial paints and coatings. It is based on UFGCC and ChameleoBoost™ technology. It boosts opacity and offers enhanced titanium dioxide performance through spacing effect and pigment stabilization. It shows very good dispersibility in water-based matt, semi-matt and semi-gloss paint systems. Omyacoat 420 provides gloss control, high brightness, reduced carbon footprint and optimized formulation cost.

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.
