Water-based Epoxy Curing Agent YD-5909K
YD-5909K is a water-based epoxy hardener modified with cyclic amines. The paint film prepared with YD-5909K exhibits good scratch resistance, excellent acid and alkali resistance, hardness comparable to oil-based coatings, and high gloss. This makes it highly suitable for applications in high-gloss, high-hardness, and high-resistance industrial waterborne coatings. It is also well-suited for emerging markets such as waterborne epoxy grouting materials and waterborne epoxy repair materials. YD-5909K can enhance the corrosion resistance and acid-alkali resistance in cement grouting materials, improving the environmental resistance of concrete.
PROPERTY
- Good scratch resistance.
- Excellent acid and alkali resistance.
- High gloss.
APPLICATIONS
Used for industrial waterborne coatings, waterborne epoxy grouting materials and waterborne epoxy repair materials, etc.

The experimental ratios for the above points 1 and 2 are as follows: YD-5909K/YD-128 = 60/40. For point 3, the experimental ratio is also 1 YD-5909K/YD-128 = 60/40. 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).
STORAGE
It should be sealed in the original packaging container, prohibited from direct sunlight, and prohibited from high temperature places.
