Application
Multipurpose SITREN® PSR 105 effectively reduces the drying shrinkage in a wide variety of different binder systems. Main applications are:
▪ Self levelling underlayments (SLU)
▪ Flowable screeds
▪ Non-shrink grouts
▪ Repair mortars
▪ Powder paints
Properties/Benefits
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
autogenous shrinkage
▪ Reduced potential for slab curling
▪ Fast curing – almost no impact on initial
setting and early strength development of
cementitious binder system
▪ 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)
Dosage and Handling
Recommended dosage rates are 0.2 – 2.0 % referred to total amount of dry components. Suitable
screening tests are recommended prior to use. For production of the drymix mortar SITREN® PSR 105 needs to be blended with the other dry ingredients by using standard mixing devices.
Registration status
The ingredients of SITREN® PSR 105 are listed on the following chemical inventories:
EINECS/ELINCS, TSCA, DSL, ENCS, AICS, TCCL, PICCS,
IECSC, New Zealand, ECS
Further information is available on request.
Storage stability
SITREN® PSR 105 may be stored in closed bags under dry conditions and below 35 °C (95 F) for 12 months. It will remain safe to use for a longer period of time. However, product quality has to be verified by appropriate tests then.
