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:
- Block resistance: the use of quartz allows faster stacking of coated substrates with the substrates sticking to each other.
- Burnish resistance: due to its hardness of 7 on Mohs scale, quartz provides good burnish resistance (low tendency to become glossy when rubbed).
- Ease of tinting: due to the combination of refractive index, brightness and color, paints including fine quartz particles will give excellent reprodicable colour results when working with tinting systems.
- Gloss control: the gloss level of an interior coating can be influenced by selecting the appropriate grade of quartz.
- Scrub resistance: due to its hardness of 7 on Mohs scale, quartz improves wet scrub resistance of interior decorative paints.
- Stain resistance: quartz acts as a supporting mineral filler in stain resistant coatings.
