Clariant showcases Innovation, Expertise and Commitment to US Market
Clariant exhibited a range of high-end products from its Pigments, Additives and Industrial & Consumer Specialties Business Units that provide innovative solutions to US customers. These solutions include Easily Dispersible (ED) pigments and new Hostatint® TS tinter colorants; Ceridust® and Licocene® waxes; Hostavin® dispersion light stabiliser and Exolit® AP flame retardant additives; and new Dispersogen® multifunctional agent for universal pigment dispersion. Clariant also featured its new product portfolio of Tinting System colourants, and dispensing- and mixing equipment and colour merchandising tools from newly acquired Italtinto SrL, an Italian Integrated tinting tystem provider.
Clariant Pigments’ line of ED pigments are organic materials that have been surface treated to allow for easier incorporation into the paint system with a dissolver and without an additional milling step. This unique technology saves processing time and energy costs that are not achievable with standard pigments. The ED portfolio of products includes three ranges of pigments: EDS pigments for solvent-based industrial paints, EDU pigments for water- and solvent-based industrial paints, and EDW pigments for water-based tinter to be used in the coloration of decorative paints.
When Clariant acquired Italtinto in April 2011, the company gained more than 40 years’ experience in tinting system technology. As a result Clariant Pigments now provides US customers with Point-of-Sale (POS) Tinting Systems designed to give customers a comprehensive solution to meet all their color needs.
At the Clariant booth, the company displayed colourant dispensing and mixing equipment from Italtinto: an IQ16 automatic colourant dispenser and a programmable TR7-fully automatic gyroscopic mixer. The IQ16 dispenser is accurate, fast and repeatable with stainless steel pistons that require virtually no calibration and has the ability to process all types of colorants, including state-of-the-art low-VOC tinter pastes. The TR7 gyroscopic mixer combines high performance mixing properties and ease of use to optimize mix times and significantly reduce air and foam in products. The TR7 runs quietly and needs little maintenance.
Clariant showed its new Hostatint TS colourant lines, products that raise the bar in low-VOC colorant technology with superior performance in outdoor paints. This allows customers to meet the latest colour trends in façade paint while complying with future regulations for low emission colorants.
The Clariant Additives business also featured Ceridust, Licocene and Licowax waxes, formulated for use in paints, coatings and inks to enhance such properties as sandability, smoothness, scratch-resistance, water-repellence and surface texture. Clariant Ceridust grades are micropowders and can be easily dispersed in paints with a minimal amount of energy. Licocene performance polymers are built upon the company’s proprietary metallocene polymerization process which produces highly effective additives for demanding applications such as powder coatings.
Arkema Coating Resins Introduces Celocor Opaque Polymer for Partial Replacement of TiO2
Arkema Coating Resins has introduced Celocor opaque polymer, a voided latex product that imparts hiding and functions as a partial replacement for titanium dioxide (TiO2).
Compared to competitive opacifiers with similar functionality, Celocor opaque polymer offers a more balanced approach to performance attributes such as tint strength, gloss development, burnish resistance and scrub resistance.
"We recognise that the cost and availability of TiO2 are among the most important issues that coatings formulators are facing today,” Eric Kaiser, Global Marketing Director for Arkema Coating Resins, explained. "Celocor opaque polymer gives paint developers more formulating options in their approach to TiO2 reduction.”
Celocor opaque polymer provides an effective way to reduce raw material costs and improve hiding in a wide range of products, including interior or exterior coatings from flat to semigloss.
Additionally, this product meets the standards of Arkema Coating Resins EnVia program and is designed to help formulators achieve their sustainability and regulatory goals in finished coating products. Celocor opaque polymer has low odour, contains no added APE surfactants or formaldehyde and is compatible with low VOC (0-50 g/l) formulations.
"Everything we do is based around the needs of the formulator,” Kaiser said. "In speaking with our customers, we found that they are very interested in having more options for TiO2 reduction while maintaining a good balance of performance attributes in their products. Our new Celocor opaque polymer meets that need.”

CN9026 Oligomer Imparts Hardness and Yellowing Resistance to Coatings for Exterior Applications
Global speciality chemicals manufacturer Sartomer USA, LLC now offers CN9026, a highly functional aliphatic urethane acrylate that demonstrates outstanding weatherability in exterior hard coat applications compared to traditional urethane acrylates. This oligomer is well suited for coatings used on automotive finishes, auto accessories made of plastic or metal and window films for
automotive and structural applications. Its scratch resistance also makes it suitable for sensitive electronic devices and their component parts.
CN9026 is a clear liquid oligomer that has high hardness, high scratch resistance and excellent resistance to yellowing.
It offers lower crosslink density than other highly functional urethane acrylates and is, therefore, more flexible at higher coat weights. For example, testing showed that a 10µm coating was completely immune to 5,000hrs of QUV accelerated weathering
exposure, showing no signs of cracking. A similar thickness industry standard urethane
failed the same test after just 1000hrs.
Formulators can download additional technical documentation at www.sartomer.com/CN9026.
