REMARKS
Setting time: The setting time of the mixture is highly dependent from
external factors, such as the mixing time and the mixing
ratio, the storage time of the material, environmental
conditions, purity and quantity of water and mixing
containers etc.
Warning: Must not be in contact with acids. Mixing with other
materials alters the product properties
