Characteristics
ASTONE is a completely homogeneous material throughout its structure, it does not separate into layers and is resistant to thermal shocks and impacts.
Material is stable when exposed to UV radiation and has better resistance to heat than other materials, ensuring that brief exposure to high temperature, such as cigarette ash and hot oil, will not damage it. ASTONE material is completely impervious to most chemicals and is completely non-porous, which among other things makes it ideal for places like hospitals, laboratories and health clinics.
Processing
ASTONE is a very thankful material that is suitable for many different types of processing: cutting, sawing, drilling, grinding, forming into different shapes, and seamless joining. The material is mechanically processed by using carbide tools.
Depending on the chosen abrasive and polishing medium, the surface layer can be shiny or matte. Therefore, ASTONE is an ideal material for design process, and we will be glad to help you turn your ideas into reality in terms of preparation and processing of ASTONE material.
The matte finish is recommended for working surfaces prone to intensive wearing, while shiny finish is less resistant and has mainly decorative purpose.
Hygienic aspect
When applied in bathrooms and sanitary facilities in form of integrated washbasins where the connection between the washbasin and panels is made without visible joints, accumulation of dirt is completely prevented as well as possible development of fungi, thus providing the highest hygienic standards.
Ecology
Production of ASTONE material does not pollute the environment and does not release greenhouse gases. Material itself can be recycled directly. ASTONE was tested by IGH and the Public health institute of Zagreb.
Consequently, ASTONE is not harmful to health and contains no hazardous substances. This material belongs to a group of self-extinguishing materials (class B non-combustion) and does not release toxic or corrosive gases.

Cleaning and maintenance
ASTONE is very easy to clean and maintain! All you need is a sponge, water and a degreasing agent (eg. dish detergent). It can also be cleaned with alcohol or detergents intended for ceramics. To remove limescale, use a sponge soaked in vinegar or a cleaning agent based on vinegar or citric acid. Then wipe the surface with a dry fabric and you are done!
