Superhydrophobic coating protects without the price
FOCUS Axalta at Powder Coating 2016: exhibited powder coatings solutions Axalta Coating Systems has exhibited and presented at the Powder Coating Technical Conference, sponsored by the Powder Coating Institute, at the Georgia International Convention Center in Atlanta, GA, US on 11-14 Apr 2016. The offering includes Axalta's Alesta AR300, AR400, and AR500 architectural powder coatings, along with the Anodic collection. At the Axalta booth, experts showcased the Alesta Global Color Collection. This architectural powder coatings line is available worldwide and is inspired by the textures and colors of iconic locations such as China's Forbidden City and the ancient Mayan pyramids in Mexico.

Sinteplast increases Latin America footprint Argentina's Sinteplast is expanding its Latin American scope to improve its export market for paints and coatings made in the region. The company is strengthening its export potential by acquiring Brazil's Sulan. Export of Sinteplast reached around $9 M in 2015. In 2015, the Argentine market increased by around 6% due to strong architectural segment demand. Sinteplast's production was expanded by approximately 13% in 2015. The company purchased Sao Paulo-based Tintas Sulan for about $3 M in Feb 2016. Sulan has a production capacity of 360,000 L/mo of paint and coatings. Sinteplast has spent about $6 M to expand its plant lines in Ezeiza, Buenos Aires. The company has also invested around $1.6 M to expand warehouse for the $20 M just-in-time plant. It also owns enamel and resins manufacturing plant in San Luis. In 2016, Sinteplast anticipates to make 80 M L/y paint and coatings, together with 4300 tons of powder coatings. The company's $46 M expansion plan includes new product launches within the Casablanca architectural line. Its Argentine market share of the paint and coatings market is expected in improve to 21% from 16%.

Swansea (UK) and the University of Nice Sophia Antipolis (France) have published in the American Chemical Society journal ACS Applied Materials and Interfaces the development of an inexpensive and non-toxic water-repelling material inspired from the hydrophobic lotus leaf that can be used in various surfaces via spin- or spray-coating. The hydrocarbon-based material has an observed angle of around 155 degrees that is fundamentally equivalent to the best fluorocarbon-based superhydrophobic coatings, making the material a potential 'green' replacement for costly fluorocarbons. Potential applications of the development includes friction-reducing coatings for marine uses.

Hexion Inc. to offer low temperature cure powder coating resins in North America Highly durable powder coating resins, including innovative low temperature cure options, from Hexion Inc. are now available in North America. New, enhanced distribution channels will allow the company to supply its proven Albester brand of durable and superdurable polyester resins as well as its Albecor LTC brand of low temperature cure, carboxyl-terminated polyester resins. Both product lines feature superior outdoor durability, offer excellent mechanical properties and provide a smooth, nonblooming finished coating. The Albester brand is well-known for its superior outdoor durability, with over 25 years of proven performance. This resin range includes pure polyesters applied in systems that can comply with stringent international standards, such as Qualicoat, GSB and American Architectural Manufacturers Association (AAMA). Curing options include TGIC and TGIC-free solutions. The range also encompasses hydroxyl-terminated resins typically used in non-emissive polyesterurethane systems for special effects in architectural, antigraffiti and transportation applications. In response to customer demand for high-performing, environmentally preferred technologies, Hexion designed its Albecor product line of carboxyl-terminated polyester resins to allow for reduced baking temperatures, saving energy and reducing CO2 emissions while producing superior durability. Core features of these resins are: high reactivity with good flow as well as excellent mechanical and outdoor performance. These powder coating resins are blooming-free and available in high or low gloss. In addition, the shortened curing/cooling cycle times are ideal for efficiently coating massive components, such as earth-moving equipment.

C OAT I N G S Mussel-inspired coatings on Ag nanoparticle-conjugated carbon nanotubes Chinese researchers report a facile musselinspired approach to introduce functional biopolymer coatings to shield AgNP-loaded oxidized carbon nanotubes (AgNPs@oCNT), as well as to modify the interface properties. Silver nanoparticle (AgNP)-based nanohybrids have been proposed as efficient antimicrobial agents because of their robust bactericidal activity. However, the direct exposure of AgNPs poses a threat towards mammalian cells. Two kinds of dopamine-grafted functional biopolymers, heparin and chitosan, were used to reduce the Ag+ ions pre-absorbed onto the oCNT surface and simultaneously form protective coating layers. Their effects on the bactericidal activity and mammal cell biocompatibility of the AgNPs@oCNT were compared. The TEM, FTIR, and XPS results clearly verified the loading of AgNPs and the coating of functional biopolymer on the oCNT surface. Studies of broth turbidity, bacterial growth kinetics, agar plate counts, and live/dead bacterial staining revealed that the biopolymercoated nanohybrids exhibited robust bactericidal activity against both Gram negative and Gram positive bacteria, and were as effective as bare AgNPs@oCNT hybrids. The chitosan-coated samples were particularly effective because of the synergistic effects of chitosan and AgNPs. The shielding effects of the anchored functional biopolymers gave the AgNP-based nanohybrids good compatibility with endothelial cells, especially for the heparin-coated samples.
