Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.6 Peintures Résumé : Now let me turn my attention to some critical aspects of paint making, to start with the Dispersion. For certain coatings applications, it is important to maintain the stability of fine particles in aqueous suspension. The theoretical effects of pH on the suspension stability of china clay in water were evaluated, and practical (centrifuge) tests were used to determine the effects of adding different molecular weights of the polymer polyvinyl pyrrolidone (PVP) at constant pH.

Titre : Special effect paint-iridescent paints Type de document : texte imprimé Auteurs : M. Veeramani, Auteur Année de publication : 2018 Article en page(s) : p. 82-86 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Iridescence L’iridescence (aussi connu sous le nom de goniochromisme) est la propriété de certaines surfaces qui semblent changer de couleur selon l'angle de vue ou d'illumination. Des exemples d'iridescence comprennent notamment : les bulles de savon, les ailes de certains papillons, certains coquillages et certains minéraux. L'iridescence est souvent créée par une coloration structurelle de microstructures qui interfèrent avec la lumière.
Pigments à effets spéciaux
Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.6 Peintures Résumé : The meaning of iridescent is, showing luminous colours that seem to change when seen from different angles. "The drake's head has an iridescent purple sheen" also known as shimmering , shimmery, glittering, sparkling, coruscating, dazzling, gleaming, glowing, lustrous, scintillating, opalescent, opaline, multicoloured, rainbow like or rainbow coloured. Paints made using such pigments exhibit such properties. Iridescente (also known as goniochromism) is the phenomenon of certain surfaces that appear to gradually change colour as the angle of view or the angle of illumination changes. Examples of iridescence include soap bubbles, butterfly wings and seashells, as well as certain minerais. Iridescente, however, occurs when an object's physical structure causes light waves to combine with one another, a phenomenon known as interference. In constructive interference, light waves combine so that the crests and troughs line up to reinforce each other, increasing the vibrancy of the reflected colour. Constructive interference is what happens in iridescence. It causes the two waves to complement each other and strengthen the reflection. Basically, when the crests and troughs of more than one wave of light match up, their powers are magnified. When they do not match up, they are mostly destroyed.
The iridescent and interference colours achieve their reflective properties by synthetically reproducing several natural phenomena - the nacreous, or pearlescent, qualities found in fish scales or the dust of a butterfly's wing, and the shiny and reflective qualities found in certain metals and minerals.Note de contenu : - Lustre arises from layers of pigments

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.6 Peintures Résumé : In the earlier chapter I had mentioned the broad classifications of the Special Effect Pigments....a short recall..."PEARL PAINTS — If one is after a luxury look the soft pearly satin gleam of pearl paint adds a subtle yet elegant mood to a room. Pearl offers a soft natural glow as it both absorbs and reflects natural light. Pearl comes in a beautiful palette of whites and neutrals. By adding a simple smalI effect like a shimmer to feature wall in a room can really make a massive difference to the overalI space. They have good compatibility with a variety of pigment dispersions to produce thousands of shades." Note de contenu : - What is happening inside

Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : Having manufactured the bases it is very important to standardise the bases. Standardisation is a process by which the bases are to be matched with any reference sample along with some specified tests which are usually followed in the industry. This is a very important step after the bases are made. Unless standardisation is done the bases cannot be tinted as one may get a Iighter shade or darker shade or the shade after tinting is no way near to the colour card. It must be understood clearly that the colour and strength are controlled to the system standard and to which colorants are added to get desired colour. Tinting bases are white, clear and coloured for the water-based eecorative paints. In other words Standardisation of Bases has to be done first in R&D & then in production. Standardisation means properties such as weight/litre, viscosity, reducing strength, colour difference (DE), opacity, gloss, full volumes etc has to be defined with their acceptance range in the specification of each base and then approve each batch of base as per the specifications.
