This cannot be achieved without quantified test and process capability. New developments in processing equipment such as high energy recirculatory mills offer opportunities for better control but the effect of rate and energy intensity effects on hue and strength control must be clearly distinguished. All aspects of optimisation and control are aided by an appreciation of the theoretical aspects of dispersion.

Meeting the colour delivery challenge / J. A. Graystone in SURFACE COATINGS INTERNATIONAL, Vol. 80, N° 11 (11/1997)

[article]  inSURFACE COATINGS INTERNATIONAL > Vol. 80, N° 11 (11/1997) . - p. 516-523 Titre : Meeting the colour delivery challenge Type de document : texte imprimé Auteurs : J. A. Graystone, Auteur Année de publication : 1997 Article en page(s) : p. 516-523 Note générale : Bibliogr. Langues : Anglais (eng) Tags : Peinture  Fabrication  Pigment  Dispersion  Formulation  'Propriété  optique'  Couleur Index. décimale : 667.9 Revêtements et enduits Résumé : Control of colour has always represented a challenge to the industry, and one which has often only been met by a strategy of post adjustment usually involving several test cycles. New challenges have arisen from both environmental legislative pressures and the relentless quest for quality, efficiency and operational excellence. The desire for 'Right First Time'(RTF) manufacture is an example of the latter, which is at variance with the post adjustment philosophy.One response has been a greater use of blending and tinting systems using pigment concentrates, not only at the point of sale, but also for factory manufacture.This does not eliminate the need for adjustment of the concentrates themselves but it removes this step from the critical path.Environmental pressures have manifested themselves in changes to pigment manufacturing processes with some grades disappearing altogether and others needing reformulation. Water-borne and high solids technologies present new challenges to achieve pigment dispersionwith the right rheological balance and this has resulted in new generations of polymeric pigment dispersants. On the equipment side the need for emission control has resulted in closed loop mills, at the same time the available energy intensity has increased to allow faster and in some cases more complete processing. recirculatory rather than batch mode processing has give more scope for instrumental process control. Exploiting these opportunities is enhanced by an understanding of the underlying physical and chemical processes and the accuracy with which they can be measured.

Prospects for assessing the adhesive performance of coatings by non-destructive methods / J. A. Graystone in SURFACE COATINGS INTERNATIONAL. PART B : COATINGS TRANSACTIONS, Vol. 88, B3 (09/2005)

By far the majority of tests used in the coatings industry are destructive and difficult to correlate with performance. Moreover, destructive tests are incompatible with best practice in inspection and quality control. A range of non-destructive testing techniques was appraised for their ability to investigate different types of coating failure involving adhesion. Three techniques were selected for preliminary investigation, namely acoustic emission, pulse thermography and laser interferometry. All three techniques were capable of investigating different aspects of adhesive failure. Pulse thermography could detect subsurface damage not apparent to visual inspection, and acoustic emission could, under some circumstances, give information of damage initiation prior to catastrophic failure. Electronic speckle pattern shearing interferometry (ESPSI) was also able to detect sub-surface damage, and showed promise of detecting differences in strain transfer prior to any detachment failure.

Quality assurance for exterior wood coatings through European and British standards / E. R. Miller in SURFACE COATINGS INTERNATIONAL. PART A : COATINGS JOURNAL, Vol. 89, A2 (03/2006)  

[article]  inSURFACE COATINGS INTERNATIONAL. PART A : COATINGS JOURNAL > Vol. 89, A2 (03/2006) . - p. 96-99 Titre : Quality assurance for exterior wood coatings through European and British standards Type de document : texte imprimé Auteurs : E. R. Miller, Auteur ; J. A. Graystone, Auteur Année de publication : 2006 Article en page(s) : p. 96-99 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.9 Revêtements et enduits Résumé : It was once relatively easy to buy paint or varnish with a clear expectation of what the product would be. During the last 30 years, however, extensive development work within the surface coatings industries has resulted in a vastly increased range of proprietary coatings, often described in pseudo-technical terms or by non-descriptive brand names. This is partly a result of advances in technology, which may require a new vocabulary, but also the understandable desire of manufacturers to differentiate their products in the marketplace. The overall effect has been to create uncertainty on the part of users as to the most suitable types of product for a given situation. In addition, it has become almost impossible to quantify different levels of performance, appearance and cost effectiveness.
