Product Description
CSA High Efficiency Water-stopping Agent is based on calcium sulpho-aluminate cement, mixed with relevant additives in appropriate proportion, the feature of which is setting and hardening quickly with high strength high adherence while easy to use...
Performance
1. Rapid setting and hardening, short interval between initial and final setting. Under 20,the initial setting time is 3-5min,the final time is 1 min after initial.
2. Quick water stopping.
3. Slight expansion, good capability of anti-penetration. Paste curing in water after 3 days, no penetration under 1.5Mpa.
4. Specification:

5. High erosion-resistance ability to sulfate and seawater(anti-sulfate coefficient1), excellent durability,suitable for the anti-erodent and seawater projects
6. Strong adherence. Easy to adhere with the working substrate, can be worked in watery environment.
7. Easily used. Only mix with water while used.
8. Environmental product without toxin,smelling, pollution and radioactivity.
Purpose of Usage
To be Used in the urgent leaking or penetration stoppage and repairs in different kinds structure of concrete, mortar or bricks, suitable for water-proofing and anti-penetration in underground engineering, water sluicing and piping, sewage farming system, kitchens and toilets..
Using Methods.
1. Before using, cut the leaking point or seam into the shape of bell mouthing or wedge, clear away the scraps and prepare suitable tools and measuring instruments.
2. Put 1kg of the water-stopping agent into the pot, adding 0.30kg of water and mixed quickly. Construction warm water should be used if the temperature is too low.
3. Knead the thick fluid to wet agglomerate by hands. When feeling it become warm (about 3-5minutes), quickly press it against the direction of leaking, until the thick fluid is hardened (about 2-3minutes)..
