Mica is a generic term applied to a group of complex Alumino-silicate minerals having a sheet or plate like structure. Micron Mica is a grade name of Mica series, manufactured by 20 Microns Limited.

It is dry milled Muscovite Mica with enhanced brightness and high purity. The product Micron Mica has an exceptional platy structure with a very high aspect ratio.

Micron Mica is muscovite mica with general formula:
K₂O₃ ∙Al₂O₃∙6SiO₂∙H₂O/KAl₂(OH,F)₂AlSi₃O₁₀

China Clay, also known as Kaolin or Glossy Clay, falls under the Kaolinite group of clays. Kaolin is fine white clay mainly composed of Kaolinite and other related minerals such as halloysite. Kaolin is a hydrated alumino-silicate having a sheet structure.

The general formula of Kaolin is Al₂(Si₂O₅)(OH)_4. The ultimate breakdown product of most rock-forming minerals is kaolinite. It is formed through the alteration or kaolinization of feldspar-rich parent rocks by weathering or hydrothermal processes. Free Silica (grit) is the most undesirable impurity and is removed during processing by levigation, sedimentation or air-separation techniques. Using advanced techniques, Kaolin is developed as Super glossy range of quality clay. Brightness combined with ultra fine particle size of Kaolin helps to achieve excellent shade along with exceptional print, gloss and hiding.

Fastflow P/S – Low Molecular Polyethylene Wax is used as a matting wax and processing aid for hard to disperse pigments. This matt wax is also used as fillers in powder coatings, paints and printing ink. Fastflow P/S matt wax provides lubricity and increases the processing capability of the extruder to its optimum level of performance. Fast Flow P/S increases the surface protection and scratch resistance.

Lubrication with Fastflow P/S wax enable processors to run at higher through put rate. Even low dosages of Fastflow P wax create matting effect.

Silcoat DE is a diatomaceous earth based multi-functional extender that offers solutions to rationalise raw material while achieving cost reduction. Due to its specific porous microstructure and naturally occurring fine particle size, Silcoat DE traps air voids that act as tiny deflecting mirror and aid quality critical light scattering properties. It gives opacity and matting power advantage in the interior or exterior paints formulation and also guarantees high colour intensities.

Sub - Talc is high brightness and micro-particles talc produced by revolutionary new engineered milling techniques. This sub-micron talc creates a large number of lamellar particle structures leads to high aspect ratio. These lamellar particles of high aspect ratio function as spacer extenders and fill the sub-microns space between TiO₂ particles that ultimately provides an optimal light scattering effect.

The interaction of fine particle size and high aspect ratio of Sub-micron Talc lamellae with the paint components creates a strong resistance to the tension that build up in the drying film as it shrinks. Also, the Sub-Micron Talc particle acts as bridge between binder agglomerates and thereby strengthens the paint film. It significantly reduces the cracking and improves the coating appearance and durability. Sub-Micron Talc platelets reduce oxygen or water transmission and protect the binders from UV radiation. This leads to improvement in the moisture barriers properties of the exterior paints.

basofix is another leading innovation from 20 microns with an average particle size of 0. 7 microns. Especially formulated for paint, powder coating and pigment manufacturing application, the fine particles of precipitated barium sulphate in basofix impart high gloss & extensive coverage. Barium sulfate is also called as blanc fixe, a french word meaning ‘permanent white’.

basofix (blanc fixe) is chemically synthetic barium sulphate with surface modified. Its snow white colour imparts excellent shade and brightness to the end product. Ultra fine barium sulphate particles of basofix act as a spacer for prime pigments and hence contribute to the hiding with very high gloss in end application.

Vaporlite 90 t / vaporlite sl 90 t is an ultra fine natural calcium carbonate. The fine particles of natural calcium carbonate in vaporlite 90 t / vaporlite sl 90 t act as a spacers between tio₂ particles that leads to increased tio₂ efficiency in paints and coating application.

the size and numbers of the sub-micron calcium carbonate particles in Vaporlite 90 t / Vaporlite sl 90 t enable efficient separation at tio₂ particles and inhibit re-agglomeration after dispersion whereas agglomerates are less efficient at scattering light when compared to the fine primary particles. As light beams are refracted at the particle surface it follows that smaller and more numerous fine particles of calcium carbonate offer more opportunities for refraction. The minute particles of calcium carbonate particles in vaporlite 90 t / vaporlite sl 90 t and thus lead to better coating opacity and high-gloss.

Calcined clay is produced under controlled heat and temperature conditions to remove chemically bound water from Kaolin. Ultra fine particle size imparts best hiding properties with excellent sheen control and maximum scrub resistance in water-based paints. Hyper – 80 is a grade name of Calcined China clay series manufactured by 20 Microns Limited.
