POLYCARBOXYLATE SUPERPLASTICIZER R-209
Product Introduction
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.

Main performance
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.
