Usage and Handling Guidelines
To achieve optimal results, the PC-733 agent should be used according to the following guidelines:
- Application Methods: The product can be measured and mixed with water before adding to concrete, or it can be mixed with water after concrete is added. The latter method is recommended for better performance.
- Dosage: The recommended dosage is 0.10–0.40% of the cementitious material. Adjustments should be made based on specific concrete design requirements and raw material conditions.
- Preparation: If using the dry powder form, ensure thorough mixing to achieve homogeneity. After adding water, the mixture should be evenly incorporated into the concrete.
Proper handling and storage are critical to maintaining the product's effectiveness. For detailed instructions, refer to the product page.
Packaging and Storage
PC-733 is packaged in paper-plastic composite bags with a standard weight of 25 kg per bag. The shelf life is 12 months from the production date. If the product exceeds its shelf life, it must be tested before use to ensure quality. To maintain its properties, store the product in a ventilated, dry place, away from direct sunlight. Moisture-proof measures are essential to prevent degradation. After opening, use the product promptly and reseal it after each use to avoid moisture absorption.
