YD-5908 is a water-based epoxy curing agent modified with fatty amines. The paint film prepared with YD-5908 exhibits good toughness and high adhesion, making it highly suitable for applications in areas such as magnetic valves, base coatings for shared bicycles, and waterborne epoxy wall paints. YD-5908 has excellent water solubility and emulsion capability for 128 resin.

The experimental ratios for the above points 1 and 2 are as follows: YD-5908: 128 = 60:40.
For point 3, the experimental ratio is also YD-5908: 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 curing agent (theoretical value).
