MARINORD - the fight against barnacles

The project, coordinated by SP with funding from the Nordic Innovation Centre, was launched in January 2008. MARINORD – Nano-porous particulate carriers for bioactive substances in marine antifouling coatings - will last for three years with a total budget of over 12 million SEK. The project is an international collaboration between SP, YKI Institute for Surface Chemistry, Gothenburg University in Sweden, Jotun in Norway, Rohm and Haas Finland OY in Finland, BioLocus in Denmark and Cabot Corporation in the United States.

The goal of MARINORD is to develop ecofriendly, effective and economical antifouling paints with controlled release of active substances by using nano-porous particulate carriers. Different types of particulate carriers will be evaluated for release of both conventional and alternative active substances with the intention of reducing fouling.

Marine fouling is a major economic problem in shipping, offshore industry and fish farming. On vessels it leads to increased fuel consumption and hence increased emissions of greenhouse gases with negative environmental consequences. Moreover, marine fouling implies much work each season for owners of small boats for recreation or other private purposes in order to keep the boats free from fouling. Marine fouling consists of algae, animals and biofilm producing micro-organisms. Barnacle is one of the dominating fouling organisms in waters of the North Atlantic.

Alkyd/acrylic hybrid binders

The two dominating binder technologies for exterior decorative coatings are acrylics and alkyds. Both technologies have distinct advantages and disadvantages. The acrylates dry quickly, have a good colour stability and a good chemical stability. On the other hand alkyds has a high gloss and penetrate well into porous materials. The ongoing project aims at mixing these binder technologies either physically by mixing dispersions/emulsions or chemically by connecting the molecules in a copolymer. The project is investigating whether there is distinct advantages of the blends compared to the pure systems. We are studying the microstructure of the coating film and correlate that with makro properties such as strength, flexibility, liquid water permeability, gloss etc. Obvious differences can be seen on the microstructure and that is also reflected on the coating film properties. The project is about to finish. The results from the project are available only for the participating industries.

Latex paints, migration

The amount and distribution of small molecules in latex paints is vital for the film properties. For example surfactants accumulated at the paint-substrate interface affect properties such as repaintability, mould growth and gloss. In this project we are studying migration of small molecules such as surfactants to the paint film surface. We study formulation of architectural coatings for indoor and outdoor applications. We are also investigating how paint additives (thickeners, coalescing agents, biocides, dispersing agents, surface wetting agents) affect the migration. The project is about to finish. The results from the project are available only for the participating industries. .

NAPOLEON - Nanostructured waterborne polymer films

This project is a EU sponsored project with about 20 participating organisations from industry, university and research institutes. The project aims at developing nanocomposite particles (two component particles) organic/organic or organic/inorganic with a particle diameter of maximally 50 nm. The latex particles will be substantially smaller than the particles of today. It will lead among other things to a better film formation. Furthermore, will the close contact between the two phases in the nano composite particles make possible to tailor the coating film properties for various applications. The project is ongoing until summer 2009. The results from the project is available only for the participating industries, universities and research institutes.

TILLMAN

Condition Analysis of exterior painted wood is an essential element in the development of maintenance programs and maintenance operations of painted wood in outdoor use. Together with both theoretical and practical knowledge, experience is of utmost importance for a proper assessment of the condition. To be able to perform condition analysis of exterior painted wood without too great an element of subjective evaluation from the evaluator's side is highly desirable from the viewpoints of both the customers and the analysts, and it minimizes risks for future disputes concerning the facts and, by extension, any legal disputes.

Frequently, disputes between the parties to assess the painted wood surfaces are due to a lack of a common "language". This project, financed by Formas, intends to fill that gap.

For paint and varnish, several  standards are currently available for the assessment of intensity, quantity and size of common types of faults, for example blistering, cracking, flaking and chalking. Unfortunately, these standards include in many cases low-quality drawn reference images, which are often considered by the users to be very difficult to use.

The primary objective of this project is to develop a manual for the Condition Analysis of painted wood outdoors. The manual is intended as an objective tool to permit analysis for the development of maintenance programs, damage investigations, etc.

Performance evaluation of coated wood - a manual. The projet is financed by Formas.

MaxFas - a substitute for gold on electric connectors

Traditionally, relatively soft metals are used as bulk and coating for electric connectors, where the main function of the bulk is to conduct electric current, whereas, the coating is responsible for low contact resistance and corrosion protection. A common material combination is a gold coating on a copper based substrate. A drawback is that the gold coating is worn out easily. This affects the quality and in worse case leads to malfunction. In several R&D projects SP are focusing on a new type of material called MaxPhase. It is a ceramic material that also conducts electricity. MaxPhase has the potential of being both a cheaper and more robust alternative to gold and other noble metals on electric connectors. 

Within three specific projects we are heading at the following objectives:

  • To mature the MaxPhase coating technology to a level where it can substitute gold as coating on low-voltage connectors.
  • To develop relevant methods for test and qualification of MaxPhase as coating for connectors. This is needed since MaxPhase has properties very different from traditional connector materials.

In these project SP are cooperating with Swedish and European Universities and companies.

MANIAC

The EU project MANIAC resulted in a new methodology for prediction of long-term performance of coatings. The methodology is based on a combination of accelerated ageing, advanced analysis and modelling and is faster than traditional methodology based only on out-door exposure. Automotive coatings were used as a case study. Partners in the project except SP were: Volvo Car, DaimlerChrysler, Atlas MTT, Clariant, PPG, BYK-Chemie, FhG-IPA and Aston University. The project was coordinated by SP and was finalized in December 2004.

Biocide administration in coatings

The project aimed at controlling the migration of biocide to the coating surface in exterior decorative paints and anti-fouling paints to reduce growth on these surfaces. Mesoporous particles, which are easy to disperse in paints, were loaded with biocide. The role of the particles was to work as package for the biocide and release the biocide at a suitable speed. After release the biocide would migrate to the surface. The project finished in the spring 2005. The project results are available only for the participating industries.

Accelerated Ageing by means of Plasma Erosion

The project, which was financed by the EU-programme “Standards, Testing and Measurements” and eight European companies, aimed at developing an extremely fast method to degrade various paints based on low pressure- and low temperature plasma. The degradation of the paint/coating as a function of plasma exposure was correlated with natural degradation (in Florida). The method was aimed to be used as a fast screening method under the development of new coatings to separate good and bad coatings at an early stage. The project finished in the spring 2001.

Sustainable wood coatings

This project is financed by FORMAS-BIC in cooperation with the industry. The aim of this project is to create knowledge regarding optimization of surface treated wood for an increased product quality and durability. In recent times discoloration of painted wood surfaces has attracted a lot of attention. The project is based on the coming EU Boicidal Products Directive and its consequences for the coatings industry and the building sector. The objective is to create technically and cost efficient solutions that can balance environmental aspects with performance. In a long-term perspective it is necessary to compare the environmental strain for different technical solutions during their total lifetime with the technical performance. The project includes evaluation of previous research, natural and accelerated ageing of new technologies, identification of microbiological discolorations, the influence of the moisture load on discolorations, analysis of the performance of products depending on leaching of active components, evaluation of durability and service life prediction.

Environment-adapted exterior wood coatings - The quality assurance system Kauna®

Together with a national research team SP Trätek has developed a quality assured boarding for exterior usage; the Kauna®-panel. A sub objective has been to make priming with the already existing coatings available on the market, i.e. waterborne alkyd paints or “high solid” paints based on linseed oil, possible. This objective has not yet been fulfilled since the paints do not meet the functional requirements such as moisture dynamics and drying time needed. The problem with traditional solvent borne alkyds is the relatively large amount of solvents which has to be taken care of at the drying process. At this moment these solvents are dumped in the area surrounding the factories.
