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



  • 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.

  • 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.
