<Paper 5>HDPE Films with Improved Barrier & Antibacterial Properties
Prof. Regina JeziorskaIndustrial Chemistry Research Institute, Poland
The ability of spherical silica containing immobilized nanosilver (SiO2-Ag) to give antimicrobial activity to HDPE films was investigated. The thermal stability as well as barrier properties of the silica filled HDPE films were significantly better compared to the neat polymer. Moreover, higher silica contents resulted in higher storage modulus, proving that the material became stiffer. Improved resistance to microorganisms (E. coli, S. aureus, S. typhimurium, L. motocytogenes, B. subtilis and P. fluorescens) of the HDPE films containing SiO2-Ag was also observed whereas pure HDPE did not show this activity.

<Paper 6>A Sustainable and Forward-looking Preservation Concept in Paints & Coatings
Mr. Mark ZhangSchuelke & Mayr, Germany
The large number of possible micro-organisms and the enormous diversity of raw materials impose demands that cannot be covered by just one microbial active used at an acceptable dosage. Moreover, environmental acceptability, including the sustainable use of raw materials, is becoming a decisive factor to customers. The synergistic combination of benzisothiazolone (BIT), methylisothiazolinone (MIT) and bis (3-aminopropyl) dodecylamine (BDA) has proved being highly effective by minimizing the level of biocidal actives needed for preservation. With this new sustainable "full-life" protection concept, it is possible to control waterborne contaminations, provide safer manufacturing procedures, to offer an opportunity to eliminate product recalls and downtime issues. Moreover, it allows for sustainable use of raw materials due to low usage concentrations and complies with the standards of various eco-labels.

<Paper 9>Preparation and Properties of UV Curing SiO2 / Hyperbranched Polyurethane Acrylate Transparent Coatings
Prof. Weiping TuSouth China University of Technology, P.R. China
The modified silicone sol from TEOS and MAPTMS were used as inorganic components and hyperbranched polyurethane acrylate (HBPUA) were used as organic components for preparing UV-curable HBPUA/(MAPTMS-SiO2) hybrid coatings. When the content of modified silicone sol was 30wt.%, 1,6-hexanediol diacrylate was 20wt.%, composite initiators (Irgacure 184 + TPO) was 3wt.%, the gel time of HBPUA/(MAPTMS-SiO2) hybrid coatings exceed 180 days. After UV curing for 4 mins, hybrid coatings had optimal properties with transmittance of 92.8%, pencil hardness of 4H, adhesion of 0 degree, flexibility of 3 mm, impact strength of 46 kg·cm and abrasion resistance of only 17.5 mg.

<Paper 10>Hard & Invisible-Incorporating Nanosilica Technology for New Improvements in 2-pack PU Coatings
Mr. Marco HeuerEvonik Hanse, Germany
2K PU coatings can be formulated by using polyols with various chain lengths and OH-values and different isocyanate crosslinker to create different mechanical properties. By adding nanosilica composites coating properties like scratch and abrasion resistance can be improved dramatically. A correlation between nanosized silica particles and the content was found without any influence to gloss or transparency. Also barrier properties like water vapour and oxygen or water immersion resistance are highly enhanced.

<Paper 11>Improved Effects in Pigment Dispersion by Coating Additives with Advanced Polymer Architecture
Mr. Ralf KnischkaBASF SE, Ludwigshafen, Germany
In recent years, formulation additives based on new controlled free radical polymerisation (CFRP) techniques have made their way into industrial reality. Especially in pigment dispersants, well-designed acrylic block copolymers can offer improved solutions compared to conventional dispersants. It is well-known that the selection of monomer chemistry and the chain length of AB-block copolymers are key design parameters. But the extent of “structural perfection” in polymer architecture needed to realise optimum performance has not been clear so far. This paper will show recent developments using nitroxyl-mediated polymerisation resulting in high-performance dispersing agents for demanding applications, with a focus on the use in waterborne applications. Detailed analysis in determining the level of structural perfection necessary to achieve optimal results and what impact deviations from the ideal structure have on the performance will be discussed.
Ralf Knischka received his PhD in Polymer Chemistry from the University in Freiburg in 2000. He joined Ciba Specialty Chemicals in 2001 working on the development of pigment dispersants via controlled free radical polymerzation. From 2004 onward he worked in product development for various field within coatings. Since 2009, Ralf is responsible in BASF SE for PD of Formulation Additives in Coatings.
<Paper 12>Novel Application of Fluorosurfactants in Easy-Clean Architectural Paints
Ms. Charlene GuoDuPont China R&D Center, USA
New research demonstrates that dosing the fluorosurfactants in both grind and letdown stages unlock their multi-functional benefits. This reformulation method, combined with several minor adjustments in the formulation, achieves the best overall easy-clean performance in low sheen paints. Three binders and two levels of PVC were evaluated with two short chain based fluorosurfactants to demonstrate easy-clean performance. Data for household and Leneta stain cleanability, as well as water and oil contact angles will be discussed in detail. No negative impact was observed on hiding power and wet scrub resistance. The use of fluorosurfactants thus is the most effective way to improve latex paint easy-clean performance.
Ms. Charlene Guo graduated from Shanghai Jiaotong University with Master Degree. She is now working on Asian Pacific technical service for Fluorosurfactant and Fluororepellent, E.I DuPont. She has 6 years formulation experience for architectural coating and industrial coating.
<Paper 13>Thickening of Waterborne Systems: Why Hydrophobically Modified Polymers (HM-P)
Dr. Leif KarlsonAkzo Nobel Functional Chemicals, Sweden
HM-P gives very good application properties to the paint e.g. good hiding power, paint consistency and spatter resistance. The thickening mechanism of HM-P includes contribution from chain entanglements as well as hydrophobic interactions. Both the length of the hydrophobic tails and the mol.wt & structure of the polymer backbone influence the properties of HM-P. Hydrophobic latexes give strong interactions with the HM-P resulting in high thickening efficiency and may also render the paint an elastic consistency. All surface active ingredients in the paint play active roles. Paint thickened with HM-P is sensitive to the surfactants that are included in colorant formulations, which can result in a reduction in viscosity of tinted paint.
Dr. Leif Karlson took a Master Degree in organic chemistry at University of Gothenburg in 1985 and a PhD in physical chemistry at University of Lund in 2002 on a thesis titled “Hydrophobically Modified Polymers - Rheology and Molecular Associations”. Dr. Karlson has been employed at Akzo Nobel Functional Chemicals since 1985. He is now holding a position as Manager for a research group dealing with product and process chemistry.
