FEATURES
l Significantly reduce cement slurry’s consistency, improve fluidity and rheological behavior.
l Use at temperature blow 180^oC ( 356^oF,BHCT).
l Use in fresh water system. Salt-tolerant to a certain extent, perform well in 5%-10% salt water cement slurry.
l Mix with water or dry mix, no water quality required and soluble in cold water.
l The performance may reduce while using in half-saturated salt water system.
PACKING AND STORAGE
l It is packed with 25kg bag. It can also be packed according to user requirements.
l Normally used within 18 months after production. If expired, test should be done to confirm the quality. Store in ventilated, cool and dry area, avoid exposing to sun and rain. The height of stack should be less than 8
