Water-based Epoxy Curing Agent YD-5911
YD-5911 is a solvent-free aliphatic amine modified waterborne epoxy curing agent, can be applied in the primer of waterborne flooring. It can emulsify YD-128 epoxy resin, and the primer can be applied at 5℃. The touch dry time of the primer is 1-2h, and then it can be directly used as water-based epoxy mortar medium coating. Hardness and strength will be established in 10-13h, and then it can be sanded. YD-5911 can be diluted with water in any proportion, and has good compatibility with cement, and it is recommended to be used in cement grouting material and cement repair mortar. In the actual application, the cost of solvent-free epoxy grout is relatively high, while the cement grout cost is low, but the poor corrosion resistance of cement is very easy to be corroded, YD-5911 can get a balance between the two, to maintain low cost while also improving the corrosion resistance of cement grout.
PROPERTY
- Solvent free.
- Good compatibility with cement.
- High cost-effectiveness.
APPLICATIONS
Used for cement grouting materials and cement repair mortar.

| Active Hydrogen Equivalent Weight (AHEW) | 180 |
PROPERTIES
| Item | Standard Range |
| Pot-life(23℃, 100g) | 20-50min |
| Pot-life(5℃, 100g) | 50-90min |
| Shore D(23℃, 3d) | ＞80D |
| 1:1 Add water standstill(24h) | Water white transparent |
| 1:1 Add water than curing with YD-128 | No phase |
| Adhesion (Glossy tile surface, 50μm, hard dry) | Level 0-1 |
| VOC | ＜40g/L |
The experimental ratios for the above points 1 and 2 are as follows: YD-5911/YD-128 = 30/30. For point 3, the experimental ratio is also 1 YD-5911/YD-128 = 30/30. After stirring thoroughly, a 50μm paint film was prepared on a tin plate and naturally cured for 7 days. The adhesion was tested using the cross-cut test method. Point 4 refers to the weight of volatile organic compounds contained in 1L of the waterborne epoxy
hardener (theoretical value).
RECOMMENDED APPLICATION
YD-5911 applied to water-based grouting
Part A:water-based epoxy dispersion 5310-W73
Part B:Tap-water/YD-5911=75/25
Part C:42.5 strength cement/middle sand/surface sand/water reducing agent=400/400/200/0.7
A/B/C=1.5/4/25, mix Part A and Part B agents evenly first, then add Part C material and mix evenly. Let it cure naturally at 23±2℃.
| Days | Compressive strength |
