Talcum Powder

---

■ Brief Introduction

Talcum powder is mainly composed of magnesium silicate hydrate, molecular formula 3MgO⋅SiO₂​⋅H₂​O, white scale-like crystals, and contains fibers. Talc crystal is monoclinic crystal system, hexagonal or rhomboidal. Talc powder is the softest minerals with Mohs hardness 1, density 2.7~2.8g/cm3, good chemical inertness, high temperature resistance up to 800℃. Talcum powder has the advantages of non-toxic, tasteless, soft texture, smooth appearance and smooth

■ Product Features

• It is mainly used to reduce cost and improve the filling performance of primer.

• Improve adhesion and solvent resistance of coatings.

• Improve product rigidity and reduce product shrinkage.

• Improve the heat resistance of the product and can be applied to biodegradable materials.
