2. Research Needs – The View From a Raw Material Supplier

Eastman Chemical Company, USA
Dr Robert J. Clemens, Vice-President Technology

Most research and development activities are accomplished through academia and industry, and are strongly influenced by the government agencies and consumers that ultimately fund the work. This talk explores the interdependence of academia and industry in this process of discovery and commercialization, especially as related to coatings, with an emphasis on places where deliberate interaction makes the most sense. The author concludes with some suggestions for establishing productive and satisfying academic/industrial relationships.

3. YKI Institute for Surface Chemistry, Stockholm, Sweden

Dr Anders Larsson, Area Manager Coatings

The presentation of YKI, Institute for Surface Chemistry will first briefly describe how YKI works with its customers and try to apply surface chemistry in many different industrial fields. One consequence of this approach is that methods and processes well established in one industrial sector effectively can be transferred to other sectors.

Traditionally the Swedish research institutes have been very small and fragmented. Nowadays clustering of the institutes occurs into fewer and larger groups. YKI clustered with SP Swedish Technical Research Institute and became a daughter company as of 1 January 2006. The coating activities within the SP group are networking heavily and the group decided to form the Scandinavian Coatings Center (SCC) with its web page www.sp.se/scc. SCC has a huge instrument park, unique technology platforms and dedicated researchers to meet the needs of the coatings industry today and tomorrow. The Scandinavian Coatings Center wishes to collaborate and network with other leading institutions in Europe to provide the coatings industry in Europe and around the globe with a competitive edge. The research at YKI during the early 1990s focussed on formulating paints in water instead of using the traditional solvents. During the late 1990s and early 2000s the focus was to understand the more complex film formation behaviour of these systems and understand the consequences on properties. Presently we try to optimise the performance of paints and coatings by the following approaches:
(i) controlled and extended delivery of biocides using mesoporous particles as carriers;
(ii) control film formation to distribute additives in a coating film at will;
(iii) co-operate with instrument manufacturers to improve productivity in coating laboratories;
(iv) optimise performance of coatings using environmentally-friendly components.

4. Université de Haute Alsace, Mulhouse, France

Dr Céline Croutxé-Barghorn, Assistant Professor
Department of Photochemistry

Radiation curing in organic photopolymers has proved its value in terms of high technical performance with both ecological and economic advantages. Understanding and controlling the photochemical processes both in time and space represent the research in the Department of Photochemistry for more than thirty years. Conventional lights and laser beams induce photochemical processes in polymeric materials concerned with many applications in the Radiation Curing area such as coatings, paints, varnishes, adhesives, inks, in the photopatterning area such as computer-to-plate technology, printed circuit board and semi-conductors, three dimensional machining, optical elements and optoelectronic devices... Although all these applications are based on a very limited set of primary reactions, the huge amount of photosensitive systems, monomers and resins, the technical and economical constraints as well as the need of innovations make the development of photopolymers very challenging and competitive. With a scientific and technical staff of about 40 persons the Department of Photochemistry investigates most of the different technical applications of photopolymers and collaborates with companies from all over the word. Different approaches have been adopted over the years to solve both academic and industrial problems related to photopolymers. The investigation of the molecular details governing the polymerization reaction is of great importance. This is achieved by developing new laser spectroscopy techniques that allow the investigation of excited states and primary processes involved in the different (photo-)chemical reactions. Development of coatings and varnishes represent an important research activity that has recently taken advantage of dual-cure or water-based systems, powder coating and hybrid organic / inorganic resins. Applications of photopolymers to the optical field are also investigated by developing photopolymeric holographic recording materials, photoinduced refractive index gratings and focusing on polymer nanolithography. The Department of Photochemistry has become an important help for industries by proposing and formulating innovative photosensitive systems. The synergy between university and industry has always been a strong interest of this lab. The activities focus on know-how transfer and range from basic research to industrial achievements.

5. Politecnico di Torino, Turin, Italy

Dr Roberta Bongiovanni, Associate Professor
Department of Materials Science and Chemical Engineering

In the last years nanostructured coatings have been receiving wide interest for their good mechanical properties (including scratch and abrasion resistance), their low permeability and thermal resistance. Also the improvement of the surface characteristics of the coatings, such as adhesion, water and oil repellency, has always been a major goal in this field.
The present paper will discuss how the UV-curing technique is suitable both for preparing organic-inorganic films and for the selective surface modification of the systems. In the first part of the speech one will illustrate the preparation of nanostructured coatings either by dispersion of particles suitably modified ( silica, titania nanoparticles or zirconia clusters) or by creating in situ inorganic nanodomains by sol-gel process in the presence of an inorganic precursor (alkoxysilanes or alkoxytitanates). Epoxy and acrylic systems will be described; the use of hyperbranched structures in UV-curable matrices will also be mentioned.

In the second part of the talk the tailoring of the surfaces will be presented, with reference to the enhancement of the adhesion and to the obtaining of hydrophobic and oleophobic materials, mainly using perfluoropolyether acrylates and hyperbranched fluorinated monomers.

6. Materials Research Institute, Sheffield Hallam University, UK

Dr Heming Wang, Research Fellow

Organic-inorganic hybrid sol-gel coatings are of increasing interest in industry due to their potential widespread applications. A brief outline of the very recent developments undertaken within our research laboratory of the different sol gel coating/pre-treatment systems will be presented. Sol-gel coatings offer alternatives to existing anti-corrosion coatings to improve the corrosion resistance of steel, aluminium alloys or other metals. Sol-gel thick coatings can be applied by varying the inorganic/organic ratio and doping various inorganic micro or nano-particles such as Al2O3, TiO2, and ZrO2, which increases the hardness and the scratch-resistance of the coatings compared with organic coatings. Sol-gel coatings are transparent generally; however, colour coatings can be obtained by doping various pigments such as carbon black. Sol-gel coatings also provide an environmentally-friendly alternative pre-treatment to that Cr (IV)-based system on substrates such as aluminium, magnesium, and steel. Functionality can be incorporated into the formulation, for example anti-bacterial properties, hydrophobic surface or varying electrical conductivity. Current problems or future developments in sol-gel coatings may also be addressed.

7. Research Needs – The View From a Paint Company

Beckers Industrial Coatings, UK
Dr Garnett Simmons, Development Manager

Paint is a complex "preparation" (according to the REACH legislation) it is a formulated blend of polymers, dispersed solid particles of pigments and fillers; catalysts and performance enhancing additives; and (usually) a carrier fluid based on either water or organic solvent. Most of these components are proprietory industrial products of undisclosed and sometimes imprecise composition, and in a complex formulation the drying/curing reactions are far from straightforward. To add further complexity the paint is never judged in isolation, but in how it performs its functions of protection and decoration of a surface. This requires a knowledge of the substrate and its interface / interphase with the coating, as well as interactions with the atmosphere at the outer surface. In this situation it is no longer sufficient to develop and control coating formulations by the old ad hoc processes.

In addition to the knowledge of "how to make paint" we need to collect sound scientific data in a very wide range of specialist areas, including - Polymer Science - Chemistry, Physics and Mechanics Fracture Mechanics, Photochemisty and its activity in curing and degradation mechanisms, Chemistry and Physics of Surfaces - Analysis by XPS; ToFSIMS etc. Fine particle dispersions - Colloids Knowledge of Substrates - Metallurgy,Wood; Plastics, The Science behind Corrosion of different substrates in different environments, Electrochemical assessment of corrosion protection, Colour Measurement, Prediction and Correction, "Cure" measurement - beyond a calibrated "thumb" Nanoparticles / fibres / tubes and potentially lots of...."things we don't know we don't know" for the coatngs of the future

The Coatings industry needs high tech expertise, knowledge and equipment, and no individual company can possibly have everything "in house". Our interface with Universities and Academia is not an intellectual indulgence, it's vital to our future. We need to work closely together

10. Institute of Macromolecular Chemistry, Prague, Czech Republic

Dr Milena Spirkova, Senior Research Fellow

This lecture will be aimed at complex epoxy-based organic - inorganic (O-I) hybrid nanocomposite coatings being characterized by high degree of self-assembly of in-situ formed nanometer-size inorganic structures. Due to nano-scaled inorganic domains the transparent and colorless products arise. Ways of their preparation creating either in the form of coatings or free-standing films will be summarized. Reaction conditions for optimizing of overall process of preparation will be outlined. The complex characterization of 'bulk' properties (i.e. features characterizing the material as an integer) and surface attributes will cover the area from molecular up to macroscopic size. Relevant scattering, microscopy and spectroscopy methods in the connection with mechanical analysis will be used for this purpose. The study of utility properties of O-I coatings for pertinent practical applications make the integral part of the contribution. The influence of nanoadditives differing in size, composition, shape and concentration on the preparation process and on final coating properties will be discussed as well.

11. Dutch Polymer Institute, Eindhoven, The Netherlands

Dr John A. E. H. van Haare, DPI Program Coordinator of the Coatings Technology Area and
Prof. Dr. Claus D. Eisenbach, Scientific Chairman CT Area

The Dutch Polymer Institute (DPI) is a public-private partnership foundation established by industry, universities and Dutch government set up to perform exploratory pre-competitive research in the area of polymer science and engineering. DPI operates at the interface of universities and industry, linking the scientific skills of university research groups to industrial needs for innovation.

The DPI was founded in 1997 initially starting with 9 Dutch based multinational chemical companies and 4 main universities. During 10 years of continuous growth the DPI strongly grew toward a European institute with at the moment 36 industrial partners and 34 university partners all around Western Europe. Besides Corporate Research DPI now explores 7 technology areas that are at the focal interest of the industrial members, namely Polyolefins, Performance Polymers, Coatings Technology, Functional Polymer Systems, High-Throughput Experimentation, Bio-Inspired Polymers, and Large Area Thin Film Electronics. In the meanwhile DPI has grown to a mature institute recognized as the expert institute on polymer science and technology for closing the gap between academic knowledge and industrial innovations. Furthermore, the extensive expertise network of the DPI is frequently used by SMEs for assistance in the development of new plastic based products. Therefore, the DPI established a new spin-off called DPI Value Centre dedicated to valorization of polymer science by creating and assisting start-up companies, building consortia for further development and helping SMEs with understanding specific polymer processing issues and development of new products.
