Applications :

Paints :It is used in various paints like distempers, cement primer, wood primer, texture paint, spray plaster, putties, fillers &undercoats.

• China clay due to its lamellar structure imparts toughness to coatings and tends to reinforce the films.
• It settles slowly in water and having low solubility in water, it is commonly used in water based paints.
• Due to its low solubility in the aqueous phase and its ability to impart good brushing and leveling characteristics, it is mainly used in latex paints.

Adhesives & SealantsIn adhesives & sealants, china clay gives good barrier effects and rheology control. The controlling rheology influences the speed at which adhesive can be applied which is important in high speed paper laminating processes. The low surface hydroxyl content of calcined China clay leads to a low moisture pick-up, resulting in excellent performance in moisture sensitive sealant applications. Calcined clay is also effective as structure building components

PlasticIt is used as a filler in combination with others to impart strength & smoothness in plastic Industry for PE master batch; PE cables; PE film; PVC cables; PVC extrusions; PVC plastisols; PP moldings; polyamide moldings; PBT/PET moldings; unsaturated polyester; urea formaldehyde; phenol formaldehyde

CeramicsChina Clay is also called “KAOLINE”, it is one of the essential Raw materials for ceramic Industries. China Clay does not swell on adding water & Alumina present in Clay do not form Isomorphous series with any other metallic compound. It is naturally hydrated Aluminum Silicate and is one of the most abundantly available clay in the Earth’s crust. China Clay is the heart of potteries, tiles, ceramics, Glazes and many other industries.

GlassThe China Clay can be effectively used in manufacturing of fiber glass because of its high alumina content.

PaperIt is used in variety of papers, cardboards, hard boards and others.

RubberGrit free china clay having low bulk density, possessing reinforcing properties, is used as filler and to improve tensile, flexural modules & make a significant increase.

Electrical IndustryIt is used for Electrical insulation, High voltage insulation components, electrical wires, EPDN rubber and others.

Cosmetics & SoapChina Clay is used in toothpaste, cosmetics and soap industry.

Other usesChina clay is used in white cement, Refractory bricks and in port, it acts as fog removing agent, dust collecting agent on road and fireproof agent of textile

Calcite is the principal constituent of limestone and marble. Calcite, the most common form of natural calcium carbonate (CaCO3). Calcite has a hardness of three on the Mohs scale, and that makes it suitable as a low-hardness abrasive. It is softer than the stone, porcelain, and plastic surfaces found in kitchens and bathrooms but more durable than dried food and other debris that people want to remove. Its low hardness makes it an effective cleaning agent that does not damage the surface being cleaned. A large percentage of the calcite, the most abundant of these carbonate minerals, occurs in limestones, It is additionally utilized as fillers in cosmetics. It is added to swimming pools as a disinfectant agent and as pH corrector. Some of the earliest paints were made with calcite. It is a primary ingredient in whitewash, and it is used as an inert coloring ingredient of paint. On reacting with dilute acids, calcium carbonate gives carbon dioxide. CaCO3 is gotten by utilizing carbon dioxide and slaked lime as raw materials. At the point when carbon dioxide is gone through slaked lime, calcite is acquired. Another strategy to get calcite is by adding sodium carbonate to calcium chloride
