SITREN® PSR 105 is a powdered shrinkage reducing additive. The active components are organic alcohols on an inorganic carrier.
Typical Applications
Multipurpose SITREN® PSR 105 effectively reduces the drying shrinkage in a wide variety of different binder systems. Main applications are
- Self-levelling mortars (SLU/SLO)
- Tile adhesives
- Flowable screeds
- Non-shrink grouts
- Repair mortars
- Waterproofing membranes
- Powder paints
Benefits at a glance
SITREN® PSR 105 functions by reducing capillary tension of pore water, a primary cause for drying shrinkage. In addition, SITREN® PSR 105 provides the following benefits
- Superior reduction of drying as well as plastic shrinkage
- Reduced potential for slab curling
- Good workability properties
- 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)
