Incompatibility Alkalinity of wet calcium silicate corrodes aluminum. Hazardous Decomposition None. Hazardous Polymerization Will not occur. The primary acute health effects of this product include mechanical irritation of the skin and eyes and skin dryness as a result of contact with amorphous silica. This product may contain trace amounts of crystalline silica as a natural contaminant in the raw materials.
Crystalline silica is considered a hazard by inhalation.
Several studies have been conducted to determine the risk of cancer to workers exposed to dusts which contain crystalline silica. However, these studies did not consider other factors or elements that workers may be exposed to. Therefore, the causes of the excess deaths due to cancer could not be precisely determined. Further studies are being conducted to determine the risk of cancer when working with crystalline silica products. Excessive exposure to crystalline silica can cause silicosis, a non-cancerous lung disease.
