1. urethane foam spray for waterproof
2. leaking stoppage material
3. polyurethane foaming agent
SL-669 Hydrophilic PU Foaming waterproofing product
1.When going through water, it will immediately swell due to chemical reaction.
2.Low swell ratio, high toughness.
3.High sticky& good property of resistant- chemical
4.Non-toxicity after the reaction
5.Being able to resist drinking water, sea water, waste water and so on.
SL-669 is used for improving the floor, such as sand layer easy to collapse, so firstly injecting SL-669 completely mixing & solidified with the sand to form the elastic colloid, avoiding to collapse. SL-669 is single-liquid polyurethane hydrophilic foaming and can rapid swell when going through water so as to block the cracks up to the purpose of water-sealing. Also, it can be together with low catalyst. You can regulate the speed of foaming according to requirements of construction to leak stoppage. Besides, SL-669 forms the colloid when going through water, which has the function of leak stoppage & filling cracks. SL-669 is mixed with water at the proportion of 1:1, 1:5, even 1: 12.
1. It has a good hydrophilic, and it can react to water so as to block up high pressure water.
2. It can bond with concrete firmly, and can create high strength concretion.
3. The viscosity can be regulated, and it can go deep into the tiny crack in order to stop leakage fast.
4. Innoxious, no pollution and no damage to human body, it can be used for drinking water project.
5. It finishes the solidification when going through water after 20-120 seconds.
6. It has well sticky with concrete and good collegiality, no delaminating with concrete.
7. It doesn’t affect the physical property of the foaming when going through mete-acid, sea water and so on.
8. It has a long-time water resistance, strong structure & high toughness.
Scope of application
Leakage stoppage at expansion joint, window frame, tunnel, crack, diaphragm wall, box culvert, hair crack, roof, etc. Ground improvement
