SITREN® SRA P 260 is a powdered shrinkage reducing additive based on a polyether on an inorganic carrier.
Typical Applications
SITREN® SRA P 260 effectively decreases the shrinkage of cementitious, dry-mix and specialty mortar formulations, that can occur when the formulation is losing moisture during the drying process. 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 260 functions by reducing capillary tension of pore water, a primary cause for drying shrinkage. In addition SITREN® SRA P 260 provides the following benefits
Further information is available on request.
- Superior reduction of drying as well as plasticshrinkage
- Reduced potential for slab curling
- Fast curing – almost no impact on initial setting and early strength development of cementitious binder system
- Very low contribution to VOC (volatile organic compound) – allows to formulate final products that meet e.g. EMICODE EC1PLUS regulation
- Good workability properties
- Reduces the magnitude of capillary stresses and shrinkage strains
- Improved impermeability and durability
- Low impact on air void content of the mortar – no formula adjustment needed, good workability
- Excellent long-term stability in dry mortar formulations
- Easy-to-use powder (not hygroscopic)
