PACKAGING AND STORAGE CONDITIONS
HDCem is packed in soft containers weighing up to 1 ton, equipped with a triple polyethylene liner. The product should be stored in a dry place on pallets, away from moisture, open flames and heating appliances. After the bag has been opened, it must be carefully closed to avoid damage to the product.
The shelf life of the product is not less than 12 months.
HDCem is a multi-component mixture of materials, predominantly of inorganic origin
Increased early and final strength;
High hydrostatic pressure in the annulus space, which prevents gas, oil and water inflow
RESTRICTIONS CONCERNING THE USAGE
Operating temperature range: from 25°С to 110°С
