Performance Additives for Superior Surface Finishes

At Prithvi Chemicals, we supply specialized mineral fillers and functional additives engineered to enhance the performance, texture, durability, and finish quality of paints and coating systems. Our materials are selected to ensure consistency, workability, and long-term stability across decorative and industrial applications.

Talc

Talc is a hydrated magnesium silicate mineral (Mg₃Si₄O₁₀(OH)₂) manufactured in various micron sizes.

Applications:

• Paints and coatings
• Ceramics
• Cosmetics

It improves smoothness, enhances suspension properties, and contributes to better surface finish and durability.

Calcined Kaolin

Calcined Kaolin is widely used as a functional filler and coating material.

Used in:

• Paints and coatings
• Paper products
• Industrial processing systems

It enhances opacity, improves brightness, and strengthens coating films.

Hydrous Kaolin

Hydrous Kaolin acts as an extender and additive in coating formulations.

Applications include:

• Paint and coatings
• Plastics and rubber
• Wire and cable
• Paper and ceramics

It offers lightweight properties with low bulk density while improving finish quality and rheology control.

Matting Agents

Matting agents modify surface gloss levels in paints, coatings, and inks.

They:

• Reduce surface gloss
• Improve texture uniformity
• Enhance mechanical surface properties

Essential for achieving controlled matte or satin finishes in modern coating systems.

Zinc Stearate

Zinc Stearate functions as a lubricant, release agent, and processing aid.

In paints and varnishes, it:

• Improves dispersion
• Acts as a surface sealer
• Enhances moisture resistance
• Provides thickening and anti-block properties

It also serves as an activator in rubber vulcanization processes.

Aluminum Silicate

A compound formed from aluminum, silica, and oxygen, sometimes combined with water to create clay structures.

Applications:

• Industrial fillers
• Medicinal uses
• Specialty coatings

It enhances structural stability and performance in coating systems.

Mica

Mica is an alumino-silicate mineral with a natural plate-like structure.

• High brightness and purity
• Reflective and refractive properties
• Natural pearl-like luster

Used to enhance durability, aesthetic finish, and decorative coating performance.

Silica

Silica is a versatile industrial material used in:

• Specialty coatings
• Fillers and extenders
• Abrasives and polishes
• Ceramics and electronics
• Rubber and refractories

It improves strength, surface hardness, and wear resistance.
