Rayonnement ultravioletIndex. décimale : 675 Technologie du cuir et de la fourrure Résumé : This study reports on the colour and gloss properties of pigment-printed polyurethane-based synthetic leather using an ultraviolet (UV)-curable water-borne polyurethane acrylate binder and two types of photoinitiators (Omnirad 819 DW and Omnirad 500) at different ratios. The UV curing of printed synthetic leather samples was conducted with gallium and mercury lamps, either singly or in combination, at three different power levels. Chemical changes in the cured films because of the polymerisation of the UV-curing process were analysed by Fourier Transform-infrared spectroscopy, which showed that the polymerisation reaction occurred after UV curing in both the clear and in the pigmented films. The Omnirad 500 photoinitiator is more effective in surface curing and the Omnirad 819 DW photoinitiator is more effective in deep curing. The Omnirad 500 photoinitiator caused the gloss values to drop significantly, especially in the formulation including both photoinitiators, Omnirad 819 DW and Omnirad 500, at a 1:2 ratio, respectively. In the formulation including a higher ratio of the Omnirad 819 DW photoinitiator, higher gloss values were obtained compared with the formulation including a higher ratio of the Omnirad 500 photoinitiator. Considering all the results, the highest gloss value of 20.96 was obtained with samples printed with the formulation of the two photoinitiators at an equal ratio (1:1) cured under a gallium/mercury lamp combination at a power level of 90 W/cm. Moreover, the highest K/S value of 10.86 was obtained with samples printed with the formulation of the two photoinitiators at an equal ratio cured under the gallium lamp at 90 W/cm.

Produits chimiques -- NomenclatureIndex. décimale : 667.2 Colorants et pigments Résumé : The generic names are the very commonly referred pigments of different chemical types. Generic name become handy to classify pigment chemical types.
The colour index generic name of the pigment indicates the 'Hue' of the pigment and the serial order in which the pigment chemical type has been registered with colour index authorities.
Assignment of generic name and number to the pigment depends upon its 'Hue' and the order in which the pigment chemical type has been registered with colour index.

Poudre -- Moulage par injection
Revêtements poudre:Peinture poudreIndex. décimale : 667.9 Revêtements et enduits Résumé : In this paper, the company gives its own view on the powder coatings market.
Powder coatings represent just 7% of the worldwide coatings market but by most industry estimates, this US$4bn industry has been successful in replacing liquid coatings in a number of key markets including appliances, wood, metal and even automotive coatings. Powder coatings are used mainly in the durable-goods markets, including motor vehicules, appliances, house wares, furniture, industrial machinery and lawn and garden equipement. The automotive industry offers excellent propects for powder coatings, particularly in the new applications such as exterior primer and clear coats.
Additionally, the appearance of consumer good is trend-led and the proportion of brightly coloured powder coatings is increasing as retailers differentiate their goods.Note de contenu : - THE PIGMENT PRODUCERS'PERSPECTIVE

vision des couleursIndex. décimale : 667.9 Revêtements et enduits Résumé : The Mission : The latest knowledge on the colour technology underpinning coatings in a single book – from the fundamentals of colour perception, to colour measurement and colour-order systems, through to the characterisation and practical application of pigments. The book serves as a vehicle for acquiring a solid grounding in the key principles underpinning the application of colour technology to coatings. Indispensable for coatings experts and those with aspirations in that direction.
The Audience : Trainees, students and newcomers to the profession who are seeking to acquire a solid grounding in colour technology, as well as experts wishing to deepen, extend or refresh their knowledge.
The Value : This book provides a comprehensive state-of-the-art survey of relevant industrial colour applications and explains the various physical physiological aspects of pigment optics. Colour problems discussed in this book include the optics and chemistry of solid-colour and effect pigments, colorant formulation, optical microscopy of effect colour shades for pigment identification, methods of elementary
and advanced colorimetry, measurement and visual assessment of solid and effect colour shades, colour tolerances and acceptability, and colour-order systems. There is also a special chapter devoted to the newly emerging area of visual texture assessment of effect colour shades.Note de contenu : 1. Fundamentals of colour perception
