18 October 2007
Silhillians Sports & Conference Centre, Warwick Road Copt Heath, Solihull, West Midlands B93 9LW
This joint Midlands Section OCCA/BSCT symposium will bring together a number of suppliers to present the various resin types and associated topics, starting mid-to-late morning, running through the day, and concluding with dinner in the evening.
Binders, film-formers… call them what you will. But Resins are the Fundamental building blocks of coatings and correct choice gives those coatings the Plus.
Aqueous, non-aqueous, VOC, performance, cure mechanisms, versatility - all factors determined by the choice of resin - and you can learn more about the resins by attending Resins - Fundamentals Plus.
A small investment for a lot of knowledge makes Resins - Fundamentals Plus excellent value and a day that will provide long term benefits.
Resins - Fundamentals Plus
Junior bench chemist through to Technical Manager; marketing through to sales; all will benefit from the comprehensive programme on offer 18th October at the Silhillians Sports & Conference Centre, Solihull. Conveniently located close to the intersection of M6 and M42 motorways, the symposium is easily accessible from the South, Midlands or North.

1.1 Keynote Address
1.2 Water-based Resins (Emulsion Polymers)
Biography: Craig has a First degree at Nottingham Trent University followed by a Masters degree in Surface chemistry with colloids at Bristol University He began working at Synthomer Ltd in 1996 as a chemist in research and development. He is currently a senior chemist in the Dispersions Research group involved with new product development over a range of different polymer types for a variety of applications and industries.
Abstract:
Synthomer, part of the Yule Catto Group of companies, are the leading supplier of emulsion polymers in the UK. Emulsion polymerisation is a convenienient way to synthesise polymers with high molecular weights at low viscosity, dispersed in water with a wide range of possible solids contents. The range of applications for emulsion polymers is very diverse. The essentials of emulsion polymerisation will be described including the process, monomer types and selection, stabilisation of polymers, particle size etc. The development of new products, which often includes scale-up from 1kg in the laboratory to 30 tonnes on production, will also be outlined.
Session 2: Thursday 18 October 2007
2.1 Epoxy Coating Chemistry: Cashew Nutshell Liquid - A Renewable Raw Material, Outshines Performances of its Conventional Counterparts
Biography:
PhD in chemistry, option heterogeneous catalysis, at the University of Louvain (Belgium). Research scientist with UCB Chemicals (hydrogenation reactions and polyesters for powder coatings); technical service and marketing management for powder coatings with UCB Chemicals; senior associate in marketing consulting with Kline & Company; global marketing manager with Cardolite Corporation. Owner of patents on hydrogenation catalyst and polyester synthesis for powder coatings; author of different papers on heterogeneous catalysis, powder coatings, protective coatings; speaker at different international conferences on coatings.
Abstract:
The recent rise in crude oil prices has awoken many people to the fact that oil will not remain an endless cheap source of energy and chemicals.
A renewable natural raw material, cashew nutshell liquid (CNSL), is used in the synthesis of a unique type of epoxy-curing agent known as a phenalkamine. While providing outstanding protection and tolerance to poorly prepared surfaces, phenalkamines cure epoxy resins very fast and allow coatings to cure at very low temperatures.
Phenalkamine-based epoxy coatings are used successfully in the shipbuilding, civil engineering and commercial vehicle manufacturing industries. They also provide good performing primers for concrete floors, even if humidity is present.
This technology demonstrates perfectly that renewable chemicals can outshine conventional technologies.
2.2 Aspects of Acrylic 2K resins
Biography: Stuart obtained a BSc from UMIST in Polymer Science in 1972 and began his career in the coatings industry at Donald MacPherson working in the Resin Development laboratory for 12 years. After 2 years in the Concrete Repair Industry he returned to resins as a Technical Sales Representative for Croda Resins in 1988. Following the acquisition by Croda of SOAB UK in 1993 he became Technical Manager at Speke, Liverpool until in 2001 Croda Resins was bought by Cray Valley. Stuart is currently Technical Manager of the PC and Marine market segment for Cray Valley.
Abstract: Acrylic 2K resins are widely used in the Coatings Industry as they are high quality systems. The basic chemistry of these will be presented and expanded to include those issues influencing the development of high solids, low VOC coatings.
2.3 UV Cure Acrylics/PE
Biography:
Joshua Oliver received his BS in Chemistry from Carnegie Mellon University in Pittsburgh, Pennsylvania, USA. He joined Sartomer Company shortly after, and spent several years working with UV technology in the fields of wood coatings, electronics, and photopolymer printing plates, before moving to France to join the team at Sartomer Europe. In the European organisation, Josh supports the graphic arts industry as a technical service and development manager, located at Sartomer’s research centre in Verneuil, France.
Session 3: Thursday 18 October 2007
3.1 New Water-borne 2K PUR Systems and their Applications
Biography: Dr Stingl is a chemistry graduate of Siegen University and obtained his doctorate in Inorganic Chemistry in 1991. After academic study he started his career as a laboratory manager for a medium-sized coatings manufacturer, before taking a management position at Bayer AG in 2001. Today he is senior manager of the Decorative Flooring & New Technology department, which is part of the Construction Coatings Business Unit within Bayer Material Science AG. As a specialist in water-borne polyurethane systems he has presented several international papers on the subject both in Europe and the USA.
Abstract:
Coating materials based on aliphatic polyurethanes have proven over decades to be of use in a variety of applications, to provide surfaces with high-grade protection against nearly all attacks from the ambient environment. Polyurethane topcoats offer a unique combination of outstanding mechanical properties, above-average chemical resistances and – in the case of aliphatic binders – good weatherability, thus making the coated surfaces particularly durable.
In numerous applications in which a small solvent content is demanded, aqueous two-component polyurethane (2K PU) coatings are today standard. Modern aqueous 2K PU coatings are characterised, like solvent-borne 2K PU coatings (dd coatings), by their excellent quality level. Therefore, from primary coating characteristics such as chemical or mechanical stability, gloss or brilliance are no longer a hurdle for the employment of aqueous 2K PU coatings.
The objective of this work was to present the newest developments of coating raw materials for water-borne 2K PUR coatings and examples of their applications.
3.2 NMP-free Polyurethane Dispersions and their Properties
Biography: Ian Martin is the R&D section leader for Industrial Copolymers Ltd. He joined ICL in September 2002 as an R&D chemist after completing his PhD in Chemistry and Polymer Science at the University of Sheffield. He has spent the past few years at ICL researching into the chemistries of epoxies and polyurethanes, developing new water-borne systems for a variety of applications.
Abstract:
Increasing environmental and legislative pressure over the years has led to a gradual shift from solvent-based polyurethanes towards water-borne polyurethane dispersions (PUDs). Although significantly more environmentally friendly, most water-borne PUDs still require the use of some solvent for processing and coalescing purposes. For many years the solvent of choice has been n-methyl pyrrolidone (NMP). However, this solvent is soon to be re-classified as a developmental toxicant (R61, risk during pregnancy of harmful effects for the child) at levels >5%. This re-classification is expected to have a significant impact on PUD technology and, in turn, the coatings industry.
Industrial Copolymers Ltd have developed a series of NMP-free PUDs and several innovative water-borne, soft-feel and UV-curable products to aid the coatings industry in their quest for a safer and sustainable future. Examples of the typical physical properties achieved with these new products and some real-life applications will be presented.
