Advantages

High water reducing rate At low dosage, it has a high water reduction effect, giving the cement material excellent fluidity, effectively improving the density and strength of cement mortar, up to 40% water reducing rate;
Suitable for all kinds of cement materials It has excellent adaptability with various types of cement materials, and is well compatible with other types of admixtures, and does not reduce the application performance of mortar under various conditions;
High dispersion It has excellent dispersion ability for cement mortar, can reduce mixing time, give cement mortar excellent workability and constructability, improve construction efficiency and meet different construction requirements;
Early strength and high strength It has excellent early strength and strengthening effect. Under the same conditions, the dosage can be reduced, and the strength increasing effect is obvious.

Uses

• Before use, PC-303 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-303 is between 0.15% and 0.30% of the binders. The exact dosage should be determined by trial mixing based on the application system and variations in the dry-mix components.

Storage

1. The shelf life is 12 months from the date of production. If the shelf life has expired, testing and verification must be carried out before use.
2. Store in a well-ventilated and dry place. Measures should be taken to prevent moisture.Keep away from direct sunlight.After opening, it should be used promptly. If not used off, it should be sealed promptly to prevent it from absorbing moisture and becoming spoiled.
