Talc (silicate, chemical formula Mg3(OH)2/Si4O10) can be characterised by:
- Lamellar nature: talc can be classified as either microcrystalline (length:thickness = 10:1) or macrocrystalline (length:thickness = 35:1)
- Low Mohs hardness of 1 (being the softest mineral in the range)
- Hydrophobic surface and, as a result, low water absorption
- High brightness
- High purity
- High inertness in various media.

Talc will provide:
- Sandability: due to its low hardness of 1 on Mohs scale, a coating with talc is very easy to sand, making it perfect for achieving a high gloss finish.
- Chemical resistance: due to its lamellar structure and hydrophobic nature, talc will provide barrier properties to the primer and good chemical resistance compared to conventional fillers.
