It is polyvinyl alcohol water loss reducing agent, equivalent to Halebarton H447, film forming water loss reducing agent and early strength development is fast, with good versatility, can be used in a variety of cement slurry systems.
Specification
Functional features
Significantly reduce water loss of cement slurry, generally can be controlled within 50ml; Increase the dosage, can be controlled within 30ml.
It has little influence on the thickening time and the early strength develops quickly.
Scope of application
Dry mixing use
Normal temperature ~ 90ºC(BHCT);
Recommended dosage: 0.5-3.0%(W/C=0.44)
The effect is better when used together with aldehydes and ketones condensates.
Storage
Store in ventilated, cool and dry environment, avoid sun and rain. The shelf life is 12 months.
