In a new study, artificial intelligence approaches are applied to predict the performance of a paper to achieve the maximum colour gamut. The colour gamut of imaging media is significant for the reproduction of colour images because its magnitude directly affects the degree to which colours change during the printing process. Over the last few years, digital impression technology has started to play a substantial role in the printing industry. The colour gamut of electrophotographic digital printing depends on various parameters including the printer and toner, but especially the properties (whiteness, roughness, and gloss) of the paper, which influence the final printed colour gamut and replication quality. In a new…

Evonik is working with two new partners to distribute the groups high-performance polymers: Ter Chemicals Distribution Group on the one hand and Biesterfeld Performance Rubber, a business unit of the Biesterfeld Group, on the other. Since October 1, 2022, Ter Chemicals took over the distribution of polyamide 12 powders across Europe, the Middle East and Africa (EMEA) and effective November 1, 2022, Biesterfeld Performance Rubber GmbH handles the distribution of a rubber additive in the EMEA region (except Italy). “Reliable partners” “We are very pleased to have Ter Chemicals and Biesterfeld Performance Rubber as reliable partners who have intact and flexible supply chains, and a strong customer focus for our…

Our editor Damir Gagro spoke to Sabrina Platzek, VP Automotive OEM Coatings Solutions Asia Pacific about the expansion of the BASF Automotive Coatings Application Center in Mangalore, India. You have Automotive Coatings Application Centers in China, Japan, Thailand and India. What role do those centers play?Sabrina Platzek: A paint formulation is only great when it works smoothly in the customer-applied paint process. Therefore, understanding and optimizing the various paint processes in combination with paint formulation expertise is the foundation of BASF Coatings’ R&D activities. BASF’s Automotive Coatings Application Centers enable us to mimic various coatings processes used in Automotive OEM production globally. Therefore, we employ state-of-the-art equipment and robotics with…

Time to read: 5 min As an engineer, you probably have experience opening, reviewing, creating, or editing STEP files. During my freshman year at Rose-Hulman, I sat in a class with 30 other students who all seemed to have an enormous amount of knowledge about 3D modeling. Meanwhile, I had never created nor even opened one before, so the first time I tried to create a 3D CAD model in SOLIDWORKS — a simple cube with a hole in the middle — I was lost.  I hadn’t learned how to visualize things in 3D as my peers did, but that first exercise challenge instilled a passion for creating and helped…

Researchers found that the addition of cardanol-modified Janus nanosheets with Zn2+ to epoxy anti-corrosion coatings significantly improves their mechanical properties and corrosion resistance Defects in the curing process of epoxy coatings tend to deteriorate the anticorrosion performance of the coatings. An important way to enhance the anticorrosion performance of epoxy coatings is to add flaky fillers. In this paper, anisotropic Janus nanosheets (JNs) were prepared and modified by cardanol (CA) and Zn2+. Then, the obtained CA@JNs@Zn2+ Janus composite nanosheets were introduced into epoxy coatings. When the content of CA@JNs@Zn2+ is 0.2 %, the mechanical properties and corrosion resistance of the coating were effectively improved. Event Tip: Anticorrosive Coatings What principles…
