How should the product be stored?

Store in a ventilated, dry place away from direct sunlight. Keep sealed to prevent moisture absorption. The shelf life is 12 months from production; expired products must be tested before use.

What are the main functions of this plastic expansion agent?

It prevents settlement and cracking by producing micro-expansion in the plastic phase, improves durability, reduces permeability, and ensures concrete mortar is dense and full.

Key features

Non-Shrinkage Performance: Compensates for plastic phase shrinkage to prevent settlement and cracking in grout and concrete.

Nitrogen-Based Expansion: Generates nitrogen gas during hydration to create uniform micro-expansion without damaging reinforcement.

High Durability & Anti-Seepage: Improves concrete density and durability, effectively reducing permeability in wet environments.

Optimized Expansion Timing: Initial foaming starts ~20 minutes before setting, ensuring effective expansion without affecting strength.

Versatile Application: Suitable for grouting materials, compression grout, concrete, and underground construction projects.

Professional Technical Support: 20 years of industry experience with a dedicated team for technical problem solving and guidance.

Flexible Customization: ODM and OEM services available; dosage and formulation can be adjusted based on specific needs.
