Materials used in countertop design
Durasein solid surface material is made with two-thirds natural minerals and one-third high performance acrylic resin and pigments. We use powdered alumina trihydrate (ATH) bound in an acrylic polymer matrix, along with pigments and inclusions.
There is no added crystalline silica in Durasein solid surface material.
Where is silica commonly found? While some common building materials contain no silica at all, Quartz and other materials are made up of as much as 95% silica:
- Quartz (Quartz Agglomerate, Engineered Stone): An aggregate of crystalline silica (mostly quartz), polymer binders, and other inclusions, it may contain 90% or more crystalline silica.
- Porcelain: Commonly used for fixtures and tile, it may be made up of 5-25% crystalline silica.
- Natural Granite: Content varies according to how the stone was formed. Samples may contain anywhere from 20-45% crystalline silica.
- Natural Marble: The content varies according to the makeup of the rock. Most marble is made up of about 2% crystalline silica.
Important note: These materials do not release respirable crystalline silica dust during normal use after installation. The risk occurs when cutting, grinding or polishing in ways that release dust into the air.
Workers can be exposed to respirable crystalline silica from poor cleaning practices such as dry brooming of dust, allowing dust to accumulate in the workplace, or using non-H class HEPA filtered vacuum cleaners.
Risks are greater when working with quartz/engineered stone, as it contains up to 95% crystalline silica.
