AkzoNobel supplies coatings to Barcelona landmark
FOCUS AkzoNobel to invest in performance coatings activities in Vietnam. AkzoNobel will double the capacity of its powder coatings plant in Dong Nai, Vietnam. Construction of the new manufacturing line will be completed in Nov 2015, resulting in 20% workforce increase. The expanded facility will serve markets in Vietnam, India, Australia, New Zealand and Southeast Asia. Aside from the expansion project, a new office for performance coatings will also be set up by the company in Ho Chi Minh City.

Stahl & OEM NuTech JV Responds to Demand for Powder Coatings for Heat Sensitive Materials Stahl and OEM NuTech have agreed to jointly develop VOC-free powder coatings for heat sensitive materials for use in architectural and interior applications. Stahl and Australian firm OEM NuTech are both strongly inclined in developing sustainable solutions. The parties have been working together for the past year and have already produced a platform to develop high quality and environmentally friendly powder coatings. Stahl employs over 1800 workers across 11 production sites and 38 laboratories in 23 countries and expects around €600 M/y of turnover.

TECHNOLOGY New Epoxy Blends for Bio-based Coatings In a study, two kinds of bio-based blends were used to enhance the properties of epoxy networks.

Commercial epoxidised cardanol, from cashew nutshell liquid (CNSL) is a biobased reactant with interesting aromatic structure. Cured with two different amines, isophorone diamine and Jeffamine T403, the materials exhibit good properties but not enough to replace the bisphenol A diglycidyl ether (BADGE) in epoxy networks. Two kinds of sucrose epoxy derivatives, sorbitol and isosorbide, were used as blends to enhance the properties of the epoxy cardanol-derived materials. These epoxy networks with different ratios were characterized by thermogravimetric analysis and differential scanning calorimetry; their hardness and brightness were measured as well as their resistance to chemical solvents. Result: Bio-based epoxy blends exhibit interesting properties for coating applications.
intramolecular bonds. Voids were observed to form during rapid quenches, as well as during much slower cooling at fixed volume, which emulates adhesion of the network to a more rigid body. The voids are large compared to the dimensions of aggressive ionic species and water molecules, and may potentially reduce the barrier properties of a crosslinked coating or composite. Such pore formation, via cavitation, during network formation and curing is not incorporated in current theories of the crosslinking process.

Alesta Powder Coatings for Brabantia’s Mineral Collection
Cavitation in Crosslinked Polymers: Molecular Dynamics Simulations of Network Formation Crosslinked organic polymers are used in a wide variety of coatings and composites to distribute stress, increase toughness and protect the substrate by limiting the passage of aggressive chemicals. Enhancing performance of crosslinked polymers requires understanding how precursor chemistry and geometry, as well as crosslinking protocol, determine the structure and performance of the resulting network. Previous molecular dynamics studies have indicated that cavitation produces pores in simulated liquids, even metals (and the resultant solids), when there is only a single type of force, usually van der Waals, between particles. Here researchers show that nano-sized cavitation voids also occur in a system bound by van der Waals (Lennard–Jones) forces that is additionally crosslinked with strong covalent (FENE) bonds to form 3 or 6 functional solid networks. Cavitation was observed in both systems. These voids are not a consolidation of "free volume'', nor due to a loss of volatiles, but happen as the solidification/cooling stresses exceed the local tensile strength of the material. At temperatures well above the glass transition temperature, "free volume'' is distributed evenly throughout the sample in very small pores. As the system cools through its rubbery phase, a few larger voids form via cavitation. Although the loci of these larger voids is associated with crosslinked nodes, cavitation involves the rupturing of weak van der Waals (Lennard– Jones) bonds between molecular chains in regions not constrained by the strong

Dutch global interior design brand Brabantia is using colours from Axalta Coating Systems' Axalta Star Collection for its Mineral Collection line of retro and Flatback+ bins. These colours are the Alesta Emerald 3 (mint green) and Alesta Azurite 3 (dark blue). Additionally, Axalta collaborated with Brabantia to develop a unique pink colour specifically created for the bins.

Galvanizing plus Powder Coat Give Excellent Protection With a gargantuan-sized powder coating line that measures 380 feet straight through, A1 Powder Coating is going after a niche market of large-size pieces that other coaters might have trouble handling. The line includes a 60-foot oven, in addition to a 55-foot wet paint booth and a 40-foot sandblasting building. Everything fits in a 61,000-square-foot building—a former shingle factory —that provides A1 plenty of room to wash, phosphate, dry, paint or powder coat, as well as bake, inspect and pack the coated parts for shipment without being exposed to the elements. In addition to the above-average size of the booths and ovens, A1 has begun offering PowderGalv, a proprietary duplex coating that is a process, and not just a coating. It starts with a hot-dip galvanized coating on a part, followed by a powder coating that gives it excellent mechanical and anti-corrosion properties. AZZ Galvanizing—which claims to be North America's largest after-fabrication galvanizer—has a shop conveniently located next door to A1's shop. The process begins with the metal pieces being fabricated and delivered to
