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.

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.

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.

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.

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.

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.

MONARCH® 120 distributed by DKSH is a low structure, specialty, general purpose carbon black. It offers very blue undertone, excellent rub resistance, good viscosity and flow properties.

• It is used as a replacement for a variety of non-carbon black pigments.
• It is recommended for a variety of inks, web offset coldset and letterpress printing inks.
• It is suitable for coatings such as underbody/underhood automotive, general industrial and architectural applications where high jetness is not required.
• MONARCH® 120 is also recommended for use as a tinting black since the large particle size allows for high loading and helps to reduce problems with floating and flooding in liquid coating applications.
• It can be easily dispersed using a single screw extruder for powder coatings.
• It is available in Netherlands, Belgium, Luxembourg and Myanmar.

Raven 410 by Birla Carbon is a carbon black with best blue undertone and lowest tinting strength for general purpose coatings. It is available both as powder and bead to ensure excellent processability in production. It possesses large particle size and low structure. It exhibits low porosity and low surface area which reduces the level of dispersant and resin demand to achieve excellent dispersion and stability. It offers low viscosity and high pigment loading in a variety of applications. It is suitable for water and solvent-borne systems. Raven 410 is used in decorative coatings, industrial coatings, powder coatings and automotive coatings.

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.
