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.

Surface modification of talc can improve the interfacial affinity between talc and polymer and improve the dispersion state of talc filler in polymer matrix. In this way, talc not only has an incremental effect in composite materials, but also has an enhancing modification effect, thereby improving the physical and mechanical properties of composite materials and enabling talc to achieve better application effects and a wider range of applications.

When choosing talc, at least the "four degrees" of talc itself should be considered, namely: purity, whiteness, flakeness and fineness. Generally speaking, in order to evaluate the quality of talc products, at least the above four factors should be considered. Judging the quality by a single indicator may be incomplete. If someone judges the quality of talc only based on the average particle size, it is very controversial.
