Paints and coatings are therefore considered enabling materials that add value to manufactured products. Think of a car without paint on it, or your nice teak wood furniture without a finish. Thin coats of paint, coating, or varnish bring life to these products and make them acceptable and durable.
Mineral particles are used as fillers in a range of applications, including paper, decorative and functional coatings, plastics and ceramics. To a mineralogist, minerals are defined primarily by their chemical composition. For the producer and end user, the physical properties of these industrial mineral products such as size and shape distribution, refractive index, density, hardness, and color are of primary importance, since it is the combination of these, together with its crystal structure and surface chemistry, which gives the mineral its functionality. The morphology of the particles constituting the mineral within a desired particle size distribution can be a key factor in determining the functionality of the end use.
There are many applications where the barrier properties of paints and coatings are key factors determining performance: For example, in protection against sunlight, air, moisture, dirt and corrosion of metals/substrate. The paint technologist therefore needs an understanding of the important parameters control ling permeability in order to design an appropriate product.
Minerals with a high aspect ratio, when aligned in a coating structure, create a tortuous path that can reduce the penetration rate of a permeating material. At a constant coat weight, there are more thin plate stacks compared to a blocky mineral system. This creates a more tortuous path for liquid and vapour penetration. So, it is clear that higher aspect ratio materials give reduction in permeability, compared to more blocky system.
In general, platy particles overlap in a film and prevent water, oxygen or other chemicals to reach the substrate basis directly, meaning the time for corrosion stimulators to start their work is increased. The addition of such platy additives in rust prevention, anti-corrosive and concrete coati ngs ensure optimal performances for surface protection.
There are many ways to define sustainability, but when most people here the word "sustainable," they immediately think "green". Often the most important, long term sustainability goal for businesses is having environmentally responsible products and practices — those that lessen or eliminate negative impacts on the environment. Environmentally sustainable practices can have long-lasting effects.
Most barrier solutions available on the market are based on polyethylene, or additives containing harmful halogens. Though these components give excellent results as a barrier but have a very harmful impact on health and environment. Therefore, ail our barrier coating is mineral based solutions having no negative impact on health and environment. They provide a prise-competitive and environmental friendly alternative.
High aspect ratio wet ground Mica provides barrier formation for anti-corrosion coatings impeding the transport of aggressive species into any metal surface.
Surface modified platy minerals for green corrosion protection coatings can be used to formulate eco-friendly corrosion protection coatings which no longer require special labelling, giving them a genuine market advantage. Even without the addition of corrosion protection pigments, these formulations provide outstanding protection.
Lamellar high aspect ratio talc increase barrier effect of the paint film by increasing hiding power, mud crack and weather resistance. Lamellar talc grades is white and produced with special grinding technique not to destroy natural lamellarity. It can be micronized without distorting it's structure due to advanced technology.
Platy iron oxide provides tough barrier surface and excellent UV absorption layer. They are excellent weather resistant and anti-rust. They are also used in zinc-rich primers.
In this study, different functional play minerals were evaluated in relation to their corrosion protection, based on barrier behavior. The following platy minerals were used for study : surface modified kaolin, lamellar high aspect ratio talc, wet groung mica and platy iron oxide.Note de contenu : - Platy minerals provide following properties in paints & coatings

HydroxyleEn chimie organique, un hydroxyle (ou oxhydryle) peut désigner deux entités.
Un groupement -OH, appelé aussi hydroxy, qui se rencontre en particulier dans les alcools et les phénols.
Un radical : HO^{\bullet}. Il est produit par exemple lors de réactions de dissociation de peroxydes, en présence d'ions de métaux de transition (Fe(II), Cu(I), réaction de Fenton), de chauffage ou de rayonnement.

SiliceLa silice est la forme naturelle du dioxyde de silicium (SiO2) qui entre dans la composition de nombreux minéraux.
La silice existe à l'état libre sous différentes formes cristallines ou amorphes et à l'état combiné dans les silicates, les groupes SiO2 étant alors liés à d'autres atomes (Al : Aluminium, Fe : Fer, Mg : Magnésium, Ca : Calcium, Na : Sodium, K : Potassium...).
Les silicates sont les constituants principaux du manteau et de l'écorce terrestre. La silice libre est également très abondante dans la nature, sous forme de quartz, de calcédoine et de terre de diatomée. La silice représente 60,6 % de la masse de la croûte terrestre continentale.
Transparence (optique)Index. décimale : 667.9 Revêtements et enduits Résumé : Liquid silica nanocomposites from Evonik are used primarily where coatings are required to exhibit high scratch and abrasion resistance without sacrificing transparency. Also, these products should be easy to formulate. Furthermore, secondary properties such as barrier effect, reduced shrinkage during curing and improved adhesion on substrates with hydroxyl function can be achieved in various coatings systems without compromising the degree of gloss. The properties can only be achieved by conventional means by using several layers. Note de contenu : - Manufacturing of silica nanocomposites
