Note: Above all are calculated based on 20% of solids content. The dosage is 1.0% of gelled material.
METHOD OF USE
Ÿ Under normal circumstance, it calculated based on 40% of solids content, dosage is 0.3%-0.75% of gelled material. The recommended dosage is 0.5%.
Ÿ Please test and find out the best dosage rate before using it.
ADVANTAGES
Low dosage 0.5~1.5% (by gelled material weight)
High water reduction up to 21~25%.
Wide adaptability, can used in all kinds of concrete projects and cement products.
Meet the international standards environmental protection rules: ISO14000.
