Quartz (silica, SiO2) is the core mineral within the Sibelco group and can be found in a broad number of applications, such as glass, ceramics and coatings. Quartz can be characterised by:
- Relatively high Mohs hardness of 7
- Low electrical conductivity
- Easy to wet
- High inertness in various media
- Shape (depending on the source, quartz particles can have an angular or more rounded shape).
Note when using quartz:
depending on the particle size distribution of the product, it can be labelled (STOT RE 2 or STOT RE 1). For more detailed information, visit www.safesilica.eu.

Quartz will provide:
- Chemical resistance: due to its inert nature, quartz will provide good chemical resistance compared to conventional fillers.
- Abrasion resistance: due to its hardness of 7 on Mohs scale, quartz will increase the coating’s resistance to wear.
- Clarity: due to its fairly low refractive index, fine quartz products become transparent when combined with certain binder systems.
- Gloss control: with the availability of ultrafine and medium size quartz flour grades, it is possible to apply coatings with a broad range of gloss levels.
- Pore and grain filling properties (sealer): with low impact on the viscosity, quartz can be used as a mineral filler in sealers to give them more body.
- Stain resistance: quartz acts as a supporting mineral filler in stain resistant coatings.
