Coloured quartz 0.4-0.8 mm

Sidec Coloured quartz 0.4-0.8 consists of washed, fire-dried and sieved quartz 0.4-0.8 mm. This gravel is not crushed, but has rolled over millions of years in a riverbed giving it its final rounded shape. To guarantee quality and to reduce the dust or excess as much as possible, the gravel is sieved very accurately. Moreover, the Sidec quartz is very pure and contains at least 98% SiO2. The relative hardness is 7 Mohs. Because the colour of the original 0.4-0.8 natural grain is mixed beige, a variegated coloured grain is generally obtained after colouring. To obtain a more uniform colour, the grain will have to be coated 2-3 times.

Sidec decorative gravel is coloured with various organic and/or inorganic pigments and then hot process coated with an epoxy or polyurethanesystem. This results in a very wear-resistant coloured granulate. The coloured gravel will be more or less resistant to UV light depending on the chosen pigments and/or resins. We recommend working with PU-coated gravel for quartz that is directly exposed to sunlight. We have added a list with a woolscale scale classification to the downloads, which will give you an idea of which colours are or are not resistant to UV light.

Possibilities: Sidec decorative gravel can be used in all kinds of applications such as: various types of synthetic floors and walls, aquariums, decorative applications, etc.

Colours: Sidec quartz 0.4-0.8 can be produced in more than 4,000 different colours, and if desired, these can be mixed to offer countless mixing options.
