polycarboxylate superplasticizer for Cement-based, oil field pc-407
PC-407 is a kind of polycarboxylate superplasticizer powderfor cement-based.which is prepared by special spray drying process, has a new generation of environmental protection superplasticizer products with high water reduction rate and high plastic retention. With a variety of cement-based cementitious materials have good adaptability and dispersion, giving the material system excellent constructability, while the strength of rapid and stable growth.
Product characteristics
(1) High water reduction rate: at low content, it has a high water reduction efficiency to adapt to low water-binder ratio.
(2) High plasticity: can maintain the rheological properties of the material system for a long time.
(3) High adaptability: It has excellent adaptability with various cement-based systems, and is well compatible with other functional admixtures.
(4) Early strength and high strength: with excellent early strength and late strength.
(5) High durability: enhance the firmness of the hardened slurry, improve the shrinkage and creep performance, and improve the durability.
Field of application
PC-407 has excellent dispersion and is especially suitable for various cement-based cementing material systems with low water-cement ratio.
— all kinds of cement morta.
