Raw talcum powder color can be in different colors and has different degrees of solid luminosity. Talc is mainly used in industrial paints and coatings, wood varnishes, printing inks, fillers as well as various coatings, increasing the coating and weather resistance The use of talc creates a barrier effect that limits the penetration of water and corrosive agents to paints and coatings, the application of talc in paint gives a wide range of benefits to paint coatings. In interior and exterior decorative paints talc acts as pigments, fillers and extenders to improve the power of feeding in industrial and household paints and primers, and it is used to improve optical and mechanical properties.

In paints, talc gives many benefits to colored concentrates, inks, glazes, varnishes, putty, body fillers, mortars and asphalts. Talc gives an anti-impact coating to the paint and increases the flexibility of the coating and also increases the color resistance to corrosion. If added to silicate, more quality coating layers are obtained, in silicate compound it releases the pigment and improves the staining effect. This makes talc a great filler in paints as it simultaneously plays a role in white and brightening the color. High-quality talc that has a surface greater than 12 square meters per gram, it is used to control the gloss when an accurate degree of gloss or luminosity is required.




The most common mineral found along with talc is chlorite, which is structurally and chemically very similar to talc mineral. Dolomite and magnesite are also often presence. Talc is able to affect the viscosity of water-based and solvent-based formulations. In paints, for example, it increases coating power, improves flow and prevents settling. It also improves the adhesion and final mechanical properties of the coating. Talc makes the dyes formulated with considerably fewer organic solvents with the necessary low viscosity. The use of talc in the formulation of a wide range of liquid products (paints, cosmetics, adhesives, etc.) also helps to control the amount of sediment during storage. Talc is used to strengthen different types of resins. Although the talc used in such applications is well chopped, it nevertheless maintains its layered structure. Magnesium oxide is a refractory solid that is physically and chemically stable at high temperatures. which has two important features: high thermal conductivity and low electrical conductivity. Silica in talc with high purity enriches important features such as brightness, oil absorption, reflection and color consistency. In paints used in buildings, silica fillers improve the preservation of paint, durability and resistance to soil, mold, cracking and air.

Talc is used in anti-corrosion primers to improve corrosion resistance and dye adhesion. Talc used in dye fabrication has some important properties such as oil absorption, fineness, viscosity and ineffectiveness. It is easily spread in solvent-based paints as well as water-based paints. Talc is an important factor that helps to disperse the reinforcing paint layers and control the viscosity and integrity and also prevents the deposition of the paint layers. It prevents solid particles from depositing in the bottom of the container. The plastic shape of talc particles improves the suspension of solids in the can and helps stick liquid paint to the walls. Since the material is very soft, Creates minimal wear for processing equipment. The ingredients of paint include polymers, pigments, solvents and additives. Polymers include polyester, acrylic, epoxy, polyurethane, vinyl and a variety of alkyds which are mainly from mineral oxides.

Additives are added to the color compound in order to accelerate dye drying and prevent the production of fungi. Talc causes strength in layers and prevents dripping and also it is used to prevent solid particles from settling in paint. This mineral reduces the requirement to consume expensive titanium dioxide in paints Talc particles strengthen the paint texture and reduce cracking and cause resistance to gradual wear and humidity in oil dyes. Talc is odorless. It is not soluble in water, weak acids and alkaline substances. Although talc has a certain tendency to some organic chemicals, it has very few chemical reactions. It is neither explosive nor flammable. Talc melting point is 1500 °C, above 900°C, it gradually loses its hydroxyl groups and above 1,050 degrees Celsius, crystallizes in different forms of statite (anhydrous magnesium silicate).
