Inorganic pigments from LANXESS are once again setting a new benchmark in terms of sustainability: In the future, the company will be offering environmental product declarations (EPDs) for all Bayferrox-branded products manufactured at its main production site in Germany – the first manufacturer of synthetic iron oxide pigments to make such an offer. These declarations describe and verify construction materials, products, or components in terms of their environmental impact. By providing them, LANXESS is creating a high degree of transparency for its customers. The parties who will benefit from this the most are manufacturers of paints and coatings, who – as part of their sustainability strategy – are optimizing their value chains by using sustainable raw materials.
The Urethane Systems business unit also put forward an extensive product portfolio for the paint and coatings industry. One focus was on raw materials for formulating aqueous systems for a wide range of applications – from glass-fiber sizings and plastic coatings, through to textile finishing or vehicle paintwork.
The Trixene Aqua BI products serve as excellent crosslinkers and adhesion promotors for aqueous coating systems. They improve the chemical and mechanical resistance not only of highly flexible textile and fabric coatings, but also of coatings for rigid substrates.
In addition to Trixene Aqua, LANXESS offers a full range of water-based polyurethane dispersions (PUDs) with its brand Witcobond. These products can be used for many applications, such as for water-based coatings and finishes for both hard and flexible substrates with a low proportion of volatile organic compounds (VOCs).
Products from the Pellart brand are used in numerous functional coatings that are subject to stringent requirements in terms of their feel, chemical resistance, luster, temperature stability, and abrasion resistance. In particular, the Pellart range really comes into its own when minimal VOC content is required.
High-quality, erosion-resistant coatings can be created using the prepolymers from the Adiprene and Trixene ranges. For example, Adiprene LFH C840 (HDI) is used for turbine blades, and Adiprene LW 520 (H12MDI) is predestined for coating aircraft wings as well as helicopter rotor blades or wind turbines.
In its wide range of colorants, the Colorant Additives business – which is part of the Polymer Additives business unit – offers aqueous pigment dispersions under the brand names Levanyl (organic) and Levanox (inorganic). These products combine high tinting strength, low viscosity and are binder-free.
Products from the Disflamoll brand offer effective flame retardance. The phosphorous-based additives are colorless and are used both in solvent-based and aqueous dispersions. They do not affect the color of the end product and are also suitable for transparent applications.
The LANXESS Flavors & Fragrances (F&F) business unit offers benzyl alcohol as a high-quality product with outstanding properties for further processing. Under the trade name Purox B, F&F supplies benzoic acid in various degrees of purity, including as one of the purest products available on the market. All forms of Purox B are easy to manage, virtually odorless, and have a low tendency to agglutinate. In the production of alkyd resins, for example, benzoic acid is an important precursor for controlling viscosity and enhancing the desired properties of the alkyd coating.

Orion's Specialty Carbon Blacks
Orion Engineered Carbons’ specialty carbon blacks are all about individual designs and highly sophisticated solutions. Specialty carbon blacks are important industrial raw materials, which are incorporated into the production processes for the polymer, printing and coatings industries. These products are outstanding in their tinting strength, conductivity, dispersibility and UV-resistance. They also perform as a viscosity-control additive and provide electro-magnetic shielding.
Orion generates more than 280 specialty carbon black grades using five manufacturing processes and after treatments. Coatings demand color perception with multivariable requirements depending on industry, application and end-use of manufactured goods. Among the color perception of coatings, carbon black generates properties for both conductive- and non-conductive- coatings. Any paint pigmented with carbon black has enhanced UV-stability that prolongs the coating's lifetime.
Among many other application fields, including liquid as well as powder coatings, carbon black is essential for automotive, industrial and decorative paints and coatings.
Earlier this year, Orion received a Gold medal rating from EcoVadis, an independent organization that assesses the performance of companies in a wide range of sustainability areas. Orion improved its score from the previous year, moving up from 72 to 77 points – just one point away from receiving a Platinum medal rating. The company is now in the 99th percentile of companies assessed by EcoVadis.
“The way Orion was able to jump five points in one year and reach the top 1% of companies shows how the many improvements we have made can add up to a big change,” said Corning Painter, Orion CEO. “We are so close to Platinum now and will continue to strive for that goal as we deliver sustainable solutions to our customers.”
In March, the company debottlenecked a post-treatment unit at its Cologne, Germany, plant that produces high-jetness specialty carbon blacks. The debottlenecking enables Orion to increase production capacity and also produce beads in addition to powder. High-jetness carbon blacks deliver a deep black masstone with a bluish undertone and are popular in automotive coatings.
“It’s challenging to push jetness above certain levels, and Orion is one of only a few carbon black producers that can do it,” said Markus Mahn, director of Global Marketing for Coatings. “Demand was high last year and continues to be strong this year.”
Orion has plans to install a second post-treatment unit at its Cologne facility due to the rapidly growing demand for the company’s premium grades.

WACKER's Innovative and Sustainable Solutions for the Construction and Coatings Industries
WACKER presented a wide range of product and application highlights. Novelties being presented for the first time were binders for high-temperature coatings and high solids, silicone additives for silicate interior wall paints, dispersible polymer powders for tile adhesives, polymer dispersions for waterproofing membranes, and a silicone resin binder for stone carpets.
With over 300 square meters of booth space and a new trade show design, the company’s booth was easy to find. A few steps away from the booth, company chemists and technical service engineers were on hand at the WACKER Academy Forum to discuss the latest product and development trends in the construction, paints, coatings and sealants industries. Nearly 30 presentations were given over the three days of the show, sustainability being a focus of most talks. And it was here that WACKER hosted the press for presentations and demonstrations about the new products introduced at ECS.
WACKER technical experts introduced several new products to the press at their booth.
WACKER’s Silicones division also focused on sustainable solutions for the construction and coatings industries: resource-conserving silicone sealants (ELASTOSIL® eco), silicone resins for solvent-free high-temperature coatings, and silicone additives for biocide-free interior wall paints were among the highlights displayed this year. “Sustainability is a key concern for us as a company,” emphasized Robert Gnann, Head of the WACKER Silicones division.
WACKER showcased 10 new products at this year’s ECS. These include:
• Two New Silicone Resins for Water- and Solvent-Based Systems for High-Temperature-Resistant Coatings
SILRES® M 51 E is a functional methyl silicone resin finely dispersed as tiny droplets in an aqueous medium. Using this kind of formulation for application on metal substrates is novel. The properties of water-based paints in which SILRES M 51 E is the sole binder are similar in quality to those of heat-resistant coatings containing solvent-based silicone resin binders. Aqueous paint formulations dry quickly and, after baking, possess exceptional chemical and mechanical strength. Following thermal stress, such coatings show excellent color and gloss resistance.
SILRES IC 900 was designed as a binder for solvent-based paints and coatings that need to withstand high temperatures. The product, which consists of an alkoxy-functionalized methyl phenyl silicone resin, is delivered as a pure, undiluted active ingredient. Its low viscosity also enables the development of high-solids coatings. The resin is characterized by a molecular structure that, when crosslinked, results in a close-meshed network that still exhibits a certain flexibility. That flexibility prevents cracks from forming in the cured coating layer, especially under conditions of thermal stress. It follows that SILRES IC 900 makes it possible to produce coatings that can be applied in thick layers.
• Polymer Resin Binder Enhances Coating Properties of High-Solids and UV-Curing Coatings
WACKER also unveiled a new polymer resin binder to formulate solventborne coatings, printing inks, high-solids, and UV-curing systems. Development of the product started with VINNOL® H 40/43, an existing polymer resin grade that is suitable for a wide range of solvents and UV monomers. In VINNOL L-6868, the mixing ratio of vinyl chloride and vinyl acetate was modified. The outcome is a decisive improvement in solubility that renders VINNOL L-6868 highly soluble in ketones as well as in esters, acrylic monomers, UV monomers and glycol esters. The combination of modified polymer composition and very low molecular weight has the effect of substantially lowering the viscosity of the polymer resin. The new binder can be used to formulate high-solids systems, i.e. those with high pigment and binder contents. VINNOL L-6868 is also suitable for reactive curing systems.
• Silicone Additive for Waterborne Silicate Paints and Brush-on Plasters
WACKER showcased a new silicone additive for formulating silicate paints and brush-on plasters for interiors. This product, which is available as an aqueous emulsion under the name SILRES BS 338, facilitates processing of the coating materials, increases their storage stability and enhances the properties of the applied coating. Wall paints and brush-on plasters produced with the silicone additive have the same breathability as before, but yield a hydrophobic, water-repellent finish.
