Sophisticated graining, a pleasant feel – elegant furniture or high-grade parquet flooring reveals wood in its finest form. At the same time, these objects must withstand the tough everyday stresses and strains. This demands the highest standards of the processing and protective properties of coatings. Whether it’s waterborne or UV systems, BYK additives optimize important properties such as gloss, scratch resistance, UV protection or durability. And consequently ensure that wood is not only good-looking but remains that way.

Michael Hindmarsh, AkzoNobel’s Marine Coatings Business, discusses how marine coatings manufacturers are going beyond their traditional remit and exploring big data, drones and new international standards to help the shipping industry meet its sustainability goals, while remaining competitive Addressing shipping industry challenges with lateral thinking solutions

017 is a year full of challenges for shipping. The industry is under 2pressure to further rationalise operations – particularly in sectors, such as the container segment, where oversupply continues to depress cargo rates. Meanwhile, new regulations like the Ballast Water Management Convention, the 2020 Global Sulphur Cap and the EU’s Monitoring, Reporting, and Verification (EU MRV) regulation, are placing pressure on profit margins and increasing the impetus on owners, operators and charterers to reduce emissions. More than ever, the industry needs smart solutions as a pioneer of sustainability within select the most efficient option for their that will drive efficiency, while reducing shipping, it is now in a position where it vessels and fleets.

Having a long established presence compare hull and propeller solutions, and saving solutions, such as hull coating and propeller manufacturers, which will, in turn, enable the industry to work towards the adoption of the most sustainable and efficient technologies. However, as a voluntary standard, the success of ISO 19030 depends on ship owners and operators understanding and recognising its benefits. This led AkzoNobel to launch a new engagement programme in March 2017 to drive industry understanding of the standard and its ramifications, providing tools, such as infographics, to help increase buy-in to the standard. AkzoNobel also championed the inclusion within ISO 19030 of a tiered system of potential methods for monitoring, including noon report data collection. This move ensured that the majority of ship owners (90%) can use and demonstrate

In recent years, more and more attention has been paid to green surfactants, which are safe, non-toxic and environmentally friendly. In this paper Xiuming Wang, Ouyang Dai, Cuifeng Zhang, Tingting Xu and Lijun Chen, present their research findings Research progress of green surfactants in preparing acrylic polymer latex

crylic polymer latex1 has been widely the functional monomers. APG0810 was used as used in many fields, such as coatings, the emulsifier. Aadhesives, textile, papermaking and leather industries because of its particular „ POLYMERISABLE SURFACTANTS properties and environmental friendliness. Nonylphenol ethoxylates (NPEOs) are widely The molecular structure of polymerisable used as surfactants for emulsion polymerisation surfactants contains the hydrophilic oleophilic to stabilise the latex. However, NPEOs are emulsion group, which can participate in the bioaccumulative and persistent in the environment, emulsion polymerisation and act as the functional while nonylphenol, the breakdown product of group. Thus, the emulsifier can be bonded on to NPEs, is an endocrine disruptor. Therefore, the EU the polymer particle surface and become a part of Commission has recommended implementing a it, which can effectively avoid desorption from the risk reduction strategy, which foresees the ban of emulsion grain surface or migration to the emulsion all applications leading to direct emissions to waste film surface8. Environmental anionic emulsifier water and strict emission controls for all other allyl oxygen radicals fatty alcohol polyoxyethylene technical processes using NPEOs as surfactants2. ether ammonium sulfate (LR- 0) and allyl oxygen In one of the major fields of application, alkyl radicals fatty alcohol polyoxyethylene ether (LG- phenol-free surfactants, with a more favourable 20) were mixed as an emulsifier in the preparing ecological profile, are becoming key ingredients of the acrylic polymer latex. Acrylic monomers for eco-friendly emulsion polymers and polymer were the main raw material and the seed semi- dispersions. In this paper, different kinds of green continuous emulsion polymerisation technology surfactants in acrylic polymer latex were reviewed. was used to prepare the acrylic latex. It was found that the adhesive performance of the latex film „ ALKYL GLYCOSIDES was superior to that of the latex film prepared by a conventional emulsifier. In addition, the effect Alkyl glycosides (APG) are a new type of non-ionic of emulsification and the stability of the latex can surfactant. It is generally soluble in water and easily be improved. soluble in common organic solvents. APG shows obvious synergistic effect with other surfactants. „ OTHER ENVIRONMENTAL SURFACTANTS Presently, APG has been used to replace the nonylphenol ethoxylates in preparing acrylic Betaine is a kind of renewable and easily polymer emulsion. Song et al3 prepared pure biodegradable amphoteric surfactant. It has low acrylate polymer emulsion with an emulsification toxicity, low eye and skin irritation. It has superior seed emulsion polymerisation. Methyl methacrylate properties, such as good surface activity in a (MMA), butyl acrylate (BA), acrylic acid, diisooctyl wider scope of pH value. Betaine amphoteric (2-EHA), acrylic acid (AA) and ethylene glycol surfactant, with unique properties, determines its methacrylate (EGDMA) were used as the anion and good distribution. Wang et al9 applied monomers and alkyl glucoside (APG0810) was amphoteric surfactant alkyl dimethyl hydroxypropyl used as the emulsifier. Shao et al4 synthesised betaine and alkyl phenol polyoxyethylene ether that acrylate polymer emulsion by adding different (OP-10) distribution as an emulsifier and used contents of APG1214. Jin5 analysed toxicity of carboxyl of itaconic acid as a functional monomer the alkyl phenol polyoxyethylene ether (APEO) monobutyl ester (MBI) to prepare the acrylic and summarised several kinds of environmentally polymer latex. Fatty alcohol polyoxyethylene ether friendly surfactants, which may well replace APEO.

With the ever increasing demands for wetting additives to meet regulatory demands and low migration in food packaging, Thorsten Schierle, Evonik Resource Efficiency, discusses the company’s latest developments Smart solutions for the challenges of modern food packaging

ood packaging is an ever-growing segment within the printing inks Fmarket. A general growth trend is observed all over the world, with more specific trends seen within the various regions. For example, the European food packaging market experiences a trend toward smaller packaging sizes; in Asia, there is a higher demand for packaged food due to expansion of the population and changes in consumer behaviour. In the food packaging market, the preferred printing technologies are flexo and gravure printing, with regional preferences for either technique. Nevertheless, the market development toward smaller lot sizes and the marketing trend toward customisation pushes the industry to develop offers • Radiation-curing inks are used for • Commercial topics, such as price- for fully or partially digitally produced aluminium foil packaging (like dairy lids) performance ratio and total cost food packaging. or narrow web labels. of formulation.

These products were designed to meet the market needs for wetting additives with distinct performance, excellent regulatory status and low migration potential. In order to achieve this, its R&D and Applied Technology departments developed these fully Swiss Ordinance A compliant wetting additives, that exhibit a low migration potential, due to their molecular weight being well above the level of 1000 Dalton. Tego Wet 550 is silicone-free and especially suitable for waterborne inks for absorbent substrates like paper and tissue. Tests on printing presses displayed defined substrate wetting and low foaming.

Jana Cohrs-Rahmoun, Regulatory Affairs Manager - FEICA, discusses the guidance papers the Association has published to assist companies in the supply chain to meet safety standards Adhesives as a food contact material

ood contact materials (FCMs) are widely used in packaging for every Fday foods and beverages. Whereas kitchen utensils tend to come into contact with foods only briefly, food packaging allows food to be stored for long periods, which means extended contact can occur. Adhesives are used in almost all food packaging, to bond the different materials used but direct food contact is rarely intended. Adhesives typically make up less than 5% of food packaging and, for most adhesive applications, direct food contact is not intended. The adhesives industry is working hard to ensure that its products are safe. FEICA, the Association of the European Adhesive & Sealant Industry, has published several „ ADHESIVES RECOMMENDATIONS manufacturing practice for materials and guidance papers to help not only their own However, no such measure exists for articles intended to come into contact members but also the other players of the adhesives at the EU level, which can, in with food” (GMP Regulation) was to cover FCM supply chain, to ensure that the final some cases, create uncertainty in the especially those materials which are not packaging is safe. supply chain.

Paint and coatings sector sees steady growth as auto industry remains strong As the automotive industry remains strong, Alan Osborne, highlights the predictions that the German economy will grow steadily over the coming year

he German paint and coatings industry is predicting that its sales Twill grow steadily in the coming year, as Europe’s largest economy continues its steady economic good fortunes. The World Bank forecasts that 2017 gross domestic product (GDP) growth will be 1.6% and in 2018 it will be 1.5%. This is good news for German paint companies, which are prime suppliers to a number of stable and largely mature markets across the German economy. The Verband der deutschen Lack- und Druckfarbenindustrie (VdL), Germany’s association for the paint and printing ink industry, recently reported that paint and coating production in Germany in 2016 rose by 1.2% yr-on-yr to 2.6Mt, with a value of just in excess of €8bn (US$8.5bn) - up 1.3%. This was ‘a good year’ said the VdL, which views 2017 with ‘cautious optimism’, predicting sales rising slightly to Photo by CEphoto, Uwe Aranas just more than 2.6Mt. Of the production in 2016, 1.17Mt was exported.

Also, suppliers had warned of price rises on the way for some pigments used by paintmakers. “This will cut into the profit margins but I think 2016 will be relatively OK where this is concerned”, Mr Bross said.

Concerned about safety? Kenya’s lead alliance provides solid base for the paint industry

Daniel Maina, CEO, Eco Ethics Kenya, organiser of a recent forum, held on October 29, as part of the 4th National Lead Poisoning Prevention Week of Action, provides his review of the event. ‘Let there be light’, mythical but perhaps the greatest rationale for paint. Colour is the spark of divine in all that is alive, deep and happy. It has been my personal effort to see that the possession of colour not only fulfils the perceptions of health but the realities as well. Kenya is a critical hub for paint in Sub-Saharan Africa and efforts to amend paint quality could see more than 150M beneficiaries. In a region where architectural paint is driven by the middle-class, chemical and structural superiority of paint, cost-effectiveness, possibilities for DIY and considerations for user and ecosystem safety, come to bear. The 4th National Lead Poisoning Prevention Week of Action was such a forum, where communities around the world, in our case Kenya, sought to interrogate the role paint could play in lowering lead exposure. Participants drawn from state agencies, government ministries, academia, industry and the civil society, converged at the Mombasa Technical The week of action took advantage Training Institute on October 29 to seek of social media, TV and radio, flyers, alternatives and allowable limits for lead in dances, speeches and word of mouth, pigments and dryers. Indeed, levels as high to disseminate our message to more as 15,000 parts per million (ppm) had been than 250,000 members of the public, documented in Kenyan paint against WHO particularly, paint manufacturers, artisans, recommendations of 90ppm. Establishing home owners, estate developers, a national standard using the 90ppm as a building contractors, public health and reference, provides a strong incentive for environmental agencies, and consumer shifting technology and attitudes towards safety groups.

A Kenya and the Mombasa Technical Training PPCJ lot more cases go unreported in developing countries due to lack of awareness and data. The impacts could be worse. Lead and other substances in paint, such as volatile organic compounds (VOCs), isocynates and other heavy metals, such as cobalt are a major cause of occupational asthma, kidney failure, lung damage and a spectra of neurological disorders. Poor practices in handling paint are responsible for falls from heights, fire accidents, spills, skin and eye irritation. To encapsulate these diverse concerns we chose to run our event under the theme ‘Exploring Paint Safety Beyond The Can’.
