Safety data sheet

SECTION 1: IDENTIFICATION OF THE SUBSTANCE/MIXTURE

1.1 Product Identifier
Calcium Silicate Slag

1.2 Name & Address of Manufacturer:
Calcium Silicate Corp.
601 Watson Farm Road
Lake Harbor, Fla 33459
Emergency contact Ph # 863-902-0217

1.3 Recommended uses:

Calcium Silicate Slag is a granular mineral employed in ceramics, to reduce crazing, cracking, and glaze defects. In metallurgical applications, calcium silicate serves as a flux for welding, a source for calcium oxide, a slag conditioner, and to protect the surface of molten metal during the continuous casting of steel. As an additive in paint, it improves the durability of the paint film, acts as a pH buffer.
