A study of the influence on hiding power of the composition of a paint and its film thickness / M. Tusar in SURFACE COATINGS INTERNATIONAL, Vol. 78, N° 11 (11/1995)

[article]  inSURFACE COATINGS INTERNATIONAL > Vol. 78, N° 11 (11/1995) . - p. 473-481 Titre : A study of the influence on hiding power of the composition of a paint and its film thickness Type de document : texte imprimé Auteurs : M. Tusar, Auteur ; L. Tusar, Auteur ; N. Barle, Auteur ; N. Leskovsek, Auteur ; M. Kunaver, Auteur Année de publication : 1995 Article en page(s) : p. 473-481 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Peinture  'Pouvoir  couvrant'  Feuil  Epaisseur  'Relation  composition  propriété'  Modélisation  'Plan  expérience' Index. décimale : 667.9 Revêtements et enduits Résumé : The main purpose of the work was to calculate the amount of pigment and the other constituents needed in the paint to provide the hiding power which will produce an opaque paint. According to DIN 53162, for the paint applied on a black and white substrate, the contrast ratio must be equal to 0.98. This means that a difference of about two percent between the value of colour on a black Yb and on a white Yw can be tolerated.

An appraisal of 2,4-dimethylthioxanthone as a photoinitiator / D. G. Anderson in SURFACE COATINGS INTERNATIONAL, Vol. 78, N° 11 (11/1995)

[article]  inSURFACE COATINGS INTERNATIONAL > Vol. 78, N° 11 (11/1995) . - p. 482-485 Titre : An appraisal of 2,4-dimethylthioxanthone as a photoinitiator Type de document : texte imprimé Auteurs : D. G. Anderson, Auteur ; R. S. Davidson, Auteur ; J. J. Elvery, Auteur Année de publication : 1995 Article en page(s) : p. 482-485 Langues : Anglais (eng) Tags : Initiateur  Pigment  Formulation  Thioxanthone  Polymerisation Index. décimale : 667.9 Revêtements et enduits Résumé : Essential features of a free radical photoinitiator system include the efficient absorption of radiant energy and the efficient conversion of the absorbed radiation into excited states which yield radicals. It is also important that the radicals produced are efficient initiators of polymerisation and that the system is thermally stable, non toxic and does not yield toxic photoproducts. The efficient absorption of energy becomes a particular problem when pigmented systems have to be cured. Titanium dioxide is a frequently used white pigment. It exhibits a band edge at 380nm. When this pigment is used, it is desirable to emply initiator systems which exhibit at least some absorption beyond 380nm. Black pigments pose particular problems since they possess very few optical windows which can be used to photoexcite initiators Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=17004 [article]

EU regulations and their impact on the coatings industry / Philippe Chatton in SURFACE COATINGS INTERNATIONAL, Vol. 78, N° 11 (11/1995)

[article]  inSURFACE COATINGS INTERNATIONAL > Vol. 78, N° 11 (11/1995) . - p. 486-490 Titre : EU regulations and their impact on the coatings industry Type de document : texte imprimé Auteurs : Philippe Chatton, Auteur Année de publication : 1995 Article en page(s) : p. 486-490 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Industrie  peinture  vernis'  Europe  Législation  'Protection  environnement'  'Prévention  pollution' Index. décimale : 667.9 Revêtements et enduits Résumé : The issue of environmental protection has grown in importance over the last 30 years. Stricter controls and standards have been set, which have added a new dimension to business. Resources have been directed towards pollution control and prevention rather than just clean-up, effecting not only management, but also product development and promotion. Environmental costs have increasingly grained recognition and businesses like coatings, ink and adhesives have begun to realise that good environmental performance can contribute to maintaining a competitive edge in the market place. The competent authorities around the world have grasped this concept and all agree tostate that a clean environment is not only a precondition for sustainable development, but it is also essential to achieve prosperity and success in the world market. Economic growth and environmental protection are not incompatible but rather components of the same goal : A safe and secure future. This paper adresses some of the key environmental issues for RadCure products and other coatings which are currently being addressed by the European EPA (Enforcement of the 7th Amendment of Council Directive 67/548/EEC, Existing Chemicals Program, Risk Assesment Directive, OECD Polymer Definition and current regularotory developments, e.g further extension of EC Directive 90/128 governing food contact applications, environmental labelling). Some issues which need to be looked at from a global prospective will also be reviewed.
