SITREN PSR 105

SITREN PSR 105 is an excellent additive for reducing drying shrinkage in formulations. The active components are organic alcohols on an inorganic carrier, making it easy-to-use and not hygroscopic. SITREN PSR 105 functions by reducing capillary tension of pore water, a primary cause for drying shrinkage. It provides superior reduction of drying as well as autogenous shrinkage. SITREN PSR 105 also reduces the potential for slab curling and fast curing with almost no impact on initial setting and early strength development of binder systems. Its benefits include good workability properties, reduced magnitude of capillary stresses and shrinkage strains, and improved impermeability and durability. These properties make SITREN PSR 105 well-suited for applications requiring long-term stability and dimensional control.
