Scope of Application
Powder Polycarboxylate Superplasticizer R-209 is a special polycarboxylate superplasticizer for dry mix mortar. R-209 has a good adaptability with cement and other admixtures and it has been widely used in non-shrinkage grouting material/mechanical grouting material, repair mortar, cement-based mortar, waterproof mortar, crack-sealer and polyphenyl granule thermal mortar, and other cement-based dry powder material. R-209 has been proved to be very helpful in improving the fluidity, early and final strength and the decreasing the shrinkage crack at the last stage of the mortar hardens. Besides, powder Polycarboxylate Superplasticizer R-209 is applicable to the gypsum-based dry powder material, fire-proof material, well drilling and ceramics.
Recommended Admixture Amount
Powder Polycarboxylate Superplasticizer R-209 is recommended to add 0.2~0.3% of the binding material when used in various dry powder materials.
