Application:

1.Wide adaptability to kinds of cements, gravels and sands, with high water reducing ratio, apply to precast concrete, especially in tubular pile precast.

2.It can bright and clean the surface of concrete. It’s suitable for pumping with small pore and low viscosity. With stable performance, it’s widely used in all kinds of concrete projects and cement product.

3.Recommended dosage (by binding materials’ weight) is 0.35%-0.65% (on the base of 50% solid content). The optimum dosage is according to the real project conditions and actual materials. Compatibility test should be done in advance when used with other additives.

Storage: Avoid direct sunlight. Keep away from fire or any kind of heat source. Stored in cool and ventilated place separately with oxidants and strong acids and alkali.

Packing: 1100 KG/IBC tank, 22 MT/20'GP
