Newt yers (2007) will mark important anniversaries for a number of key events in the history of the idea of sustainability: it will be 20 years since the publication of the Brundtland report ('Our common future'); 15 years since the Earth Summit in Rio and 10 years since the Kyoto Protocol was signed - all events which have had a significant effect on global public opinion. Neither business nor individuals can afford to ignore environmental issues any longer. The sustainability trend is driven by society's changing values, with consumers demanding that industry acts more reponsability and governments around the world introducing increasingly strict legislation to ensure it does so. International paint and coatings manufacturers are among the companies that have to comply with stricter environmental regulations, while at the same time improving product performance and meeting the requirements of consumers. Unfortunately, the environmentally friendly solutions, which could help them achieve this, are often suspected of veing less effective in terms of performance and cost - a major concern when it comes to surfactants, as the reliability and performance of these substances is essential. However, Cognis' new generation of environmentally friendly surfactants firmly refutes this prejudice. The surfactant system Disponil AFX is an example of how an environmentally conscious approach can bring market success when it does not have an adverse effect on product performance. The product range recently received official recognition from the Federation of German Industries (BDI), in the shape of the organisation's Environment Award.Note de contenu : - Regulatory compliance - the key challenge for surfactants

Titre : Multifunctional additive : Improving dispersion efficiency Type de document : texte imprimé Auteurs : Simon Poulton, Auteur Année de publication : 2001 Article en page(s) : p. 26-27 Langues : Anglais (eng) Tags : Paint Manufacturing Adjuvant Dispersant 'Grinding(comminution)' Dispersion Formulation Index. décimale : 667.9 Revêtements et enduits Résumé : A performance additive with a number of features that offer significant benefits to formulators of waterborne systems is welcome. The base strength of Bisomer Amine D 700, 77% aqueous dimethylaminohydroxypropane (DMAHP), enables effective pH adjustment and neutralisation whilst the volatile nature Improves early water resistance, gloss, and scrub resistance. Also when used in an optimised formulation, it is shown In this paper that DMAHP can reduce primary dispersant levels and hence reduce formulation costs. In addition, the tertiary amine structure enhances biocide efficiency. Note de contenu : - Experiment : dispersant demand procedure

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : The author describes how one small step in monomer development is a giant leap for resin suppliers needing cost effective and versatile marterials.
Acrylate and methacrylate monomers are the building blocks for acrylic polymers. With 400+ structures commercially cited, not to mention those specially generated in academia, the choice of unsaturated monomers can often seem bewildering. An alternative view would be to consider the choices and pressures facing the paint and resin chemist, rationalising the list of possible acrylic reagents into a practical formulating toolkit.
The paint and resin chemist needs to be far more aware of external issues relating to coatings development. For example, the impact of environmental legislation has driven coating technologies towards high solids, waterborne, powder and 100% solids systems. Customer power, on the other hand dictates performance and health & safety improvement. Internal cost control requires the use of inventory listed materials in more inventive ways.
The successful chemist needs to be knowledgeable of the available acrylic materials, have a flexible approach to customer demands and adapt the chemistry in order to meet environmental needs. And, it goes without saying that this has to be done cost effectively.Note de contenu : - Commonly used monomers

Vinyl méthyl oxazolidinoneIndex. décimale : 667.9 Revêtements et enduits Résumé : In all industrial areas, there is a constant drive to improve - from regulatory pressure for favorable toxicological profiles to enhanced technical performance and improved handling - and concerning UV-/EB-curable formulations, all application fields face similar challenges. BASF is the market leader in the supply of specialty vinyl monomers and is thus intrinsically motivated to support our'UV curing' customers. Our new monomer VMOX (vinyl methyl oxazolidinone) is a reactive diluent that helps address the current challenges. Compared to traditional reactive diluents in the industry, VMOX offers a favorable toxicological profile together with technical benefits and improved formulating capabilities. This includes it being liquid at room temperature, with a very low viscosity of 4 mPa/s (at 20°C), a high reactivity with acrylates, and low colour and odour characteristics.
Overall, VMOX is particularly suited for use as a reactive diluent in UV curing coatings, inks and 3D printing applications. While providing the beneficial technical performance vinyl monomers are known for, VMOX allows innovative formulations with a favourable toxicological profile, which recently has been a challenge and is increasingly difficult to overcome with current chemistries.Note de contenu : - Fig. 1 : VMOX structure and GHS pictogram comparison with other monomers
