TDS-NJ-705 Air-entraining Agent
NJ-705 air-entraining agent is a high-efficiency air-entraining powder modified with sodium α-olefin sulfonate. It has extremely strong calcium soap dispersing power, hard water resistance, excellent foaming properties and foam stability, and is widely used in cement/gypsum-based material systems. It has the following characteristics:
It has an air-entraining ball effect, which significantly improves the smoothness of mortar application;
Introducing stable and uniform air bubbles improves water retention and extends operating time;
Microbubbling effect, introducing micron-sized bubbles, resulting in low strength loss rate;
It has good adaptability and is well-matched with water-reducing agents, early-strength agents, and retarders.
Scope of application
This product is suitable for use in plastering, interior and exterior wall putty, thermal insulation mortar, insulation boards, foamed backfill materials, and other fields.
