SiSiB® WR5054 is a free-flowing white powder composed of a mineral carrier encapsulating reactive silicone compounds. Upon mixing with water, the silicone is released and covalently binds to the cement matrix, imparting long-lasting water repellency.
Prevent penetration of liquids entering solidified cement-based materials via surface or capillary action.
Provides long-lasting water repellency with strong beading effect
Efficient at low dosage (0.2-1.0%)
Minimal impact on compressive strength
Excellent dispersibility and compatibility with other mortar additives
Long-term performance even in alkaline environments
Maintains breathability of cementitious systems

In the unopened original packing SiSiB® WR5054 has a shelf life of at least 12 months in a dry and cool place.
Storage beyond the date does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
