Revêtements en phase aqueuse:Peinture en phase aqueuseIndex. décimale : 667.9 Revêtements et enduits Résumé : High-gloss emulsion paints have always been second-class citizens by comparison with their solvent-borne equivalents. The relatively poor dispersion and stabilisation of TiO2 pigments, typical in current emulsion paints, means that for a given volume of TiO2, emulsion paints have tended towards a lower opacity and gloss compared with that of a long-oil alkyd equivalent paint.

RéflectanceIndex. décimale : 667.2 Colorants et pigments Résumé : The author discuss the development of borosilicate based effect pigments.
Iridescent colours caused by light interference are well known in nature, such as in the colours of butterfly wings. For producing such interference effects on an industrial level naturel fish silver derive from fish silver derived fro fish scales was used in the beginning then succeeded by platelet shaped inorganic crystals (ie basic lead carbonate and bismuth oxychloride). Nowadays, pearlescent pigments based on natural mica represent by far the most important class of interference effect pigments. Those pigments consist of platelets coated with thin latyer of highly refractive metal oxide (eg TiO2) causing multiple reflection and interference oflight. Different colours can be created by variation of the thickness and material of the metal oxide layer.Note de contenu : - Borosilicate substrate

RéflectanceIndex. décimale : 667.2 Colorants et pigments Résumé : Recent advances mean bismuth oxychloride pigment is being used for variety of purposes. This paper looks at its application in coatings.
The liquid metal look is essentially a smooth, highly reflective, non-grainy appearance. This is accomplished by using either a continuous film or by using very thin platelets, on the order of 30-50 nanometers, to reduce the scattering of light from edges of platelets. It has been desirable in the automotive industry for some time and is now making an appearance in other coating applications, such as teletronics.
This is accomplished by using either a continuous film or by using very thin platelets of a highly reflective pigment. One of the pigments that satisfy these requirements is bismuth oxychloride. This pigment has been better know for applications such as button and costume jewellery coatings, but recent advances make it feasible for less traditional applications as well, such as achieving the liquid metal effect.
Bismuth oxychloride is made by the reaction of bismuth nitrate in acid solution with chloride. By suitably controlling pH and temperature, the formation of BiOCl is thermodynamically preferred over Bi2O3, bismuth oxide. With very fine control of these same parameters the crystals grow as very thin patelets. The chemical reaction is as follows :
Bi(NO3)3 + H2O + 3NaCl --> BiOCl + 2HCl + 3NaNO3
The resulting platelets are about 90nm thick at the edge and somewhat thicker in the middle. It is the shape of these platelets, along with the index refraction (about 2.0), that is responsible for its pearlescent appearance.Note de contenu : - Bi(NO3)3 + H20 + 3NaCl -> BiOCl + 2HCl + 3NaNO3

ThermoplastiquesUne matière thermoplastique désigne une matière qui se ramollit (parfois on observe une fusion franche) d'une façon répétée lorsqu'elle est chauffée au-dessus d'une certaine température, mais qui, au-dessous, redevient dure. Une telle matière conservera donc toujours de manière réversible sa thermoplasticité initiale. Cette qualité rend le matériau thermoplastique potentiellement recyclable (après broyage). Cela implique que la matière ramollie ne soit pas thermiquement dégradée et que les contraintes mécaniques de cisaillement introduites par un procédé de mise en forme ne modifient pas la structure moléculaire.Index. décimale : 667.9 Revêtements et enduits Résumé : Since I am on this subject it is necessary for me to explore the Thermo Plastic Road Marking Paint in detail, without which the topic will be incomplete. Thermoplastic Road Marking Paint, also called Hot Melt Marking Paint, is a kind of powder paint. When applied as road surface markings, a hot melt kettle is used to heat it to 200°C (392°F), after which it is sprayed on the road surface. The coating then becomes a line after cool ing. This paint is thick coating, wear-resistant, bright and reflective. In recent years, practical applications have proved that the marking lines lack certain surface roughness and can easily cause wheel slip, resulting in a traffic accident in snow and rainy weather. Therefore, some countries once restricted the use of this paint. In order to increase the antiskid performance of the line, thermoplastic paint has added reflective glass beads. Thermoplastic can be used very effectively for large Anti-skid areas on roads and pedestrian walkways by adding glass beads. It can be produced in any colour and is great for car parks, factory walkways and many other areas. It is fast drying and can be driven over after just a few minutes.
