Talc is a common filler widely used in the coating industry. Its main component is hydrous magnesium silicate with a molecular formula of 3MgO·4SiO2·H2O. Talc belongs to the monoclinic system and its crystals are pseudo-hexagonal or rhombic flakes. Talc micropowder, which is made through multiple processes, occupies an important position in the coating industry with its unique physical and chemical properties.

Talc is a commonly used filler in solvent-based coatings. Its main component is hydrous magnesium silicate talc (3MgO·4SiO2·H2O), which is a monoclinic crystal system with pseudohexagonal or rhombic flakes.

Talcum powder can give the coating excellent storage stability and heat resistance.

Talc powder is added to waterborne wood coatings mainly to take advantage of its low cost, excellent filling and good sanding performance. However, the amount of talc powder added needs to be reasonably controlled.

Talc has shown wide application potential in the construction field due to its unique properties, and has become one of the indispensable materials in the construction industry.

Because talc powder has good suspension and easy dispersion and low abrasive property, talc powder can be used as a filler for coatings. The storage stability of the coating can be improved, and the rheology and leveling of the coating can be improved, and the weatherability of the coating can be improved.
