Stable retaining crystal infiltration repair materials 
 W720 
 Advantage 
 (1) high intensity, no cracking, impermeability, suitable for the leakage of a large area of ??surface construction, to achieve the sealing purpose. 
 (2) strong adhesive, saturated wet to dry a variety of surface of the base construction. 
 Three freeze-thaw resistance, chemical corrosion. 
 (4) add the coagulant adjustable setting time. 
 (5) can water while plugging, but also for the use of bonding materials. 
 Recommended for 
 An underground waterproof plugging 
 Reservoirs, tunnels, basements, bathrooms, water seepage plugging. 
 Concrete interface treatment agent, paste, or subsidies tile. 
 Typical performance indicators 
 Setting time: the initial setting, min, and ≥ 60; final setting, min, ≤ 240 
 Compressive strength, Mpa, 3d, ≥ 25 
 Flexural strength, Mpa, 3d, ≥ 4.0 
 Pressure specimen impermeability, Mpa, 7d, ≥ 3.0

 Use 
 The grassroots level to prepare: The base should be flat, solid, clean, no oil, no debris. Before the construction of the base surface should be moist. 
 Spices: sparingly add water, put it aside for a few minutes after mixing and then stirring time you use the better. 
 3 waterproof construction: cement ratio of 0.3 to 0.35, using the scraping method for twice the thickness of 2-3mm. 
 Amount of reference: the film thickness of 1 mm, with about 2.0 ~ 2.5kg/m2. 
 Packing: 5kg / bag, 5 bags / box
