Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : We present a self-matted coating technology that allows control of the gloss of coatings without compromising the coating performance. The technology utilises water-borne, micrometre-sized polymer dispersions, and controls the gloss of coatings by adjusting the size and amount of the particles used.
We demonstrate that the self-matted technology can be used in various applications, including industrial coatings, architectural coatings and printing and packaging.Note de contenu : - The self-matted coating technology-

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : Radiation curing is often thought to be a more sustainable technology due to the reduced energy usage and carbon footprint during cure with further reductions as the industry moved from mercury lamps to modern LED technology. Increasingly, sustainability in UV technology also encompasses hazard classifications of raw materials, user safety, and component migration. This paper presents a self-reactive resin
that offers formulators greater control and ease of use while meeting specifications.Note de contenu : - High concentration of migratable material for type II photoinitiators
- Increased severity of hazard classifications
- Self reactive resins offer improved handling
- Acrylate multifunctionality boost reactivity
- Reduced migration with modified triacrylate
- LED-active resin for greater ease of use

GraphèneLe graphène est un cristal bidimensionnel (monoplan) de carbone dont l'empilement constitue le graphite. Il a été isolé en 2004 par Andre Geim, du département de physique de l'université de Manchester, qui a reçu pour cette découverte le prix Nobel de physique en 2010 avec Konstantin Novoselov. Il peut être produit de deux manières : par extraction mécanique du graphite (graphène exfolié) dont la technique a été mise au point en 2004, ou par chauffage d'un cristal de carbure de silicium, qui permet la libération des atomes de silicium (graphène epitaxié).

Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : Graphene was first isolated in 2004 by Andre Geim and Konstantin Novoselov at Manchester University. They used sticky tape to remove single layers from the surface of graphite and deposit them on a silicon wafer. The isolation of graphene was a breakthrough for which Geim and Novoselov ultimately won the 2010 Nobel prize for Physics. In its purest form, graphene possesses an unsurpassed combination of electrical, mechanical and thermal properties, which gives it the potential to replace existing materials in a wide range of applications and, in the long term, to enable new applications. Graphene's unique two-dimensional structure in the nanoplatelet form results in very high aspect ratio, high surface area materials which are particularly suited for use as multi-functional additives in paints and coatings formulations.
Applied Graphene Materials UK Ltd. (AGM) produces a range of dispersions of graphene nanoplatelets (GNPs), enabling property enhancement. AGM supplies its graphene in dispersion format, ensuring good dispersibility and stability. For this work, two graphene dispersions were used and are described.Note de contenu : - Water vapour transmission rate testing

ZincIndex. décimale : 667.9 Revêtements et enduits Résumé : Research on graphene is a fast-developing field, with new concepts and applications appearing at an incredible rate. Recent research studies have been aimed at improving the resistance of coatings against such degradation using nanomaterials. Recently the uses of graphene nano-flake rein forcements in polymeric coatings have been extensively investigated by many scientists to achieve such improvements. It has been postulated that graphene can act as a strong blocking agent and increase the resistance of coatings against UV light, moisture, oxygen, and so on. Electrochemical studies, mechanical studies have been carried out by many researchers to investigate the functional properties of graphene in coatings. The present review addresses the work done on graphene based coatings to study its performance in protective coatings. Note de contenu : - Graphene based epoxy coatings
