| Huaxuan High-tech® PC-306 PC-306 is free from chlorides and complies with ASTM C494 Type A and F. |
Conventional superplasticisers, such as those based on sulpunated melamine and naphthalene formaldehyde condensates, at the time of mixing, become absorbed onto the surface of the cement particles. This absorption takes place at a very early stage in the hydration process. The sulphonic groups of the polymer chains increase the navigate charge on the surface occurs by electrostatic repulsion.
PC-306 production reaction temperature is fixed and can be controlled. It is not like other similar PCE,whose production temperature fluctuates in high range.

Before use, PC-306 needs to be mixed evenly with other dry powder components. The construction mixing and application should be carried out according to the specific requirements of the different fields of application.
The recommended dosage of PC-306 is between 0.10% and 0.50% of the binders. The exact dosage should be determined by trial mixing based on the application system and variations in the dry-mix components.
PC-306 has excellent dispersibility and is particularly suitable for various high-grade cement systems. Such as in:
·Ultra-High Performance Concrete (UHPC)
·Other high-strength, high-performance concrete.
