R-209 is polymerized by various macromolecule organic compounds,
which is specialized for cement grouting and dry mortar. It has
good adatability with cement and other admixtures.Due to it can
enhance the fluidity,strength of final setting time,and decreased
the crack after mortar solidified,so applied in cement
non-shrinkage grouting,repair mortar,cement base flooring
grouting,water proof grouting,crack-sealer and expanded polystyrene
insulation mortar.Further, it also widely applied in
gypsum,refractory and ceramic.

1. High water reducing rate: The water reducing rate can achieve at
least 25% for mortar,enhanced the fluidity of mortar greatly.
2. Early strength and high strength: It can improve the early
strength of mortar, improve the ultimate strength,it is the best
option to the application required rapid curing.
3. High durability: It can decrease the water-binder ratio of the
mortar,improve the durability,decreased the creep and shrinkage,
crack after mortar solidified.
4. Green environmental product: It is not polluted to the
environment, up to the standard of ISO14000.
The recommend dosage is 0.2%~0.3%. It can use it directly or dilute
with water, compound with other PCE is available.
