High Grade Coatings: Technology Update
Prof. Jamil Baghdachi
Coatings Research Institute, Eastern Michigan University, USA
Abstract:
The two driving forces of nanotechnology and smart coatings in the past two decade have fueled vigorous research and development work on polymeric coatings. The result of such movement has been the development of high performance and high valued coating materials. These coatings not only function as protective and decorative materials, they also push the performance envelop well beyond traditional definition of coatings. Included in this class of new developments are high temperature resistant polymeric coatings, stimuli responsive, super high solids liquid coatings, self-stratifying, superhydrophobic/superhydrophilic, and biologically active and corrosion sensing coatings. This paper provides a brief discussion of technology, properties and application of these high performance and high valued coatings.

Abstract:
Solventborne high solids coatings are a challenge for formulators because of their high non volatile content, high viscosity and limited choice of suitable solvents. The viscosity reduction achieved by wetting and dispersing additives is thus very important in meeting VOC targets. New ways of formulating low solvent coatings and reducing costs are presented. Advice is given on choosing the right chemical structure for the formulation of 2-pack PU and 2-pack EP high solids coatings.

Novel, Low Viscosity Dimer Diamine for Bridging Flexibility & Hardness
for Marine and Protective Coatings
Mr. Hans Ridderikhoff
Croda Europe, The Netherlands
Abstract:
With the increased focus on sustainability the demand for bio-based materials is strongly increasing. Over the previous years a range of bio-based building blocks based on dimer fatty acid technology has been developed for the use in high performance coatings such as polyurethane dispersions, flexibilised epoxy coatings and UV-curable coatings. These building blocks bring excellent hydrolytic stability, outdoor stability, flexibility and adhesion to a wide range of substrates including plastic, metal and wood.
Recently an additional range of low viscous, amine-functional products have been developed to expand the application possibilities for bio-based materials. For epoxy resins, the technology provides similar benefits to dimer fatty acid based polyamide curatives, such as flexibility and impact resistance. However, this new curative allows for high solids formulations with good water repellency, pigment wetting and excellent durability.
For polyurea, the technology brings improved moisture and chemical resistance together with an excellent surface finish and impact resistance. Furthermore, the novel amine functional materials are fully bio-based (100% renewable carbon) and are completely non-volatile, so bring clear environmental and health benefits to the end-users.
About the Speaker:
Mr. Hans Ridderikhoff obtained his Master Degree of Organic Chemistry in the University of Leiden, The Netherlands in 1998. He worked at Quaker Chemical, Witco/Crompton and Uniqema from 1990-2003.

Solvent Free UV Hardcoat for Spray Application
Dr. Mouhcine Kanouni
Cytec Industries, USA
Abstract:
Radcure coatings are renowned for their hardcoat properties and thus used extensively for consumer electronic devices. Due to the high viscosity of the multi-functional urethane acrylates, the coating formulation usually requires a solvent dilution (up to 50%) for spray applications. Use of monomers instead of solvent dilution significantly lowers the hardcoat performance. A novel solvent free UV hardcoat has been developed. Using water as the diluents, the unusually high solid content product provides hardcoat properties that are similar to 100% UV resin. Performance results and properties of this technology will be detailed.
About the Speaker:
Dr Mouhcine Kanouni is currently Global Marketing Manager for Consumer Electronics & Industrial Plastics at Cytec Industries. He joined Cytec in 2008 as the Technical Service & Development Manager. For the past 12 years, prior to joining Cytec, he was attached to Ciba Specialty Chemicals where eventually he was the Global Technical Director for the lubricant additives business. He also served as an adjunct professor at several U.S. universities. Dr. Kanouni received his M.Sc. in Physical Chemistry, France. He earned his MS and Ph.D. in Physical Chemistry from City University of New York and his Business Management Degree at New York University.

Improved Effects in Pigment Dispersion by Coating Additives with
Advanced Polymer Architecture
Mr. Ralf Knischka
BASF SE, Ludwigshafen, Germany
Abstract:
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.
About the Speaker:
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.

Novel Application of Fluorosurfactants in Easy-Clean Architectural Paints
Ms. Charlene Guo
DuPont China R&D Center, USA
Abstract:
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.
About the Speaker:
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.

Thickening of Waterborne Systems: Why Hydrophobically Modified
Polymers (HM-P)
Dr. Leif Karlson
Akzo Nobel Functional Chemicals, Sweden
Abstract:
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.
About the Speaker:
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.
