SITREN® SRA P 270 is a powdered shrinkage reducing additive based on a polyether on an inorganic carrier.
Typical Applications
SITREN® SRA P 270 effectively decreases the drying shrinkage of cement-based mortars/concrete and the potential for subsequent cracking.
Main applications are
Main applications are
- Self-levelling mortars (SLU/SLO)
- Flowable screeds
- Tile adhesives
- Non-shrink grouts
- Repair mortars
- Waterproofing membranes
- Powder paints
Benefits at a glance
SITREN® SRA P 270 functions by reducing capillary tension of pore water, a primary cause for drying shrinkage.
In addition, SITREN® SRA P 270 provides the following benefits

In addition, SITREN® SRA P 270 provides the following benefits
- Superior reduction of drying as well as plastic shrinkage
- Reduced potential for slab curling
- Slight defoaming characteristics
- Good workability properties
- Very low contribution to VOC (volatile organic compound) allows to formulate final products that meet e. g. EMICODE EC1PLUS regulation
- Fast curing - almost no impact on initial setting and early strength development of cementitious binder system
- Reduces the magnitude of capillary stresses and shrinkage strains
- Improved impermeability and durability
- Excellent long-term stability in dry mortar formulations
- Easy-to-use powder (not hygroscopic)
