HY-5120 One-Component Waterborne Epoxy Resin Emulsion
HY-5120 is a one-component waterborne epoxy resin emulsion made from epoxy resin as the main component through a waterborne process. The product is a milky white liquid with good water dispersibility and can be diluted with deionized or softened water, making it convenient to apply and use. It can be used in waterborne coatings, glass fiber sizing agents, fiber surface treatment agents, waterborne adhesives, composite interfacial treatment and other waterborne systems requiring the bonding, film-forming and adhesion properties of epoxy resin.

Recommended Applications
- Glass fiber sizing and surface finishing systems
- Waterborne epoxy coatings, waterborne primers and protective coatings
- Waterborne adhesives and composite bonding systems
- Surface treatment of inorganic fillers, glass fiber, carbon fiber and fabrics
- Adhesion improvement systems for metal, wood, cement substrates and some polar plastics
- Waterborne formulations requiring improved film-forming, bonding and interfacial adhesion
Usage Recommendations
Stir evenly at low speed before use. Depending on the final formulation system, it can be diluted with deionized or softened water; add water slowly while stirring to avoid a local concentration that is too low, which may reduce emulsion stability.
When used in glass fiber sizing agents, coatings or adhesive systems, it can be compounded as needed with wetting agents, defoamers, film-forming aids, coupling agents, thickeners and other waterborne resins. If higher water resistance, chemical resistance, heat resistance or crosslinking strength is required, a matching curing agent or crosslinker can be selected according to the final application.
Before formal production, small-scale verification of dilution stability, compatibility, adhesion, water resistance and application performance is recommended.
Storage & Transportation
Packaging:50 kg and 200 kg plastic drums or as per customer requirements
Storage conditions:Store in a cool, dry and ventilated place at a recommended temperature of 5-35°C. Avoid sunlight, high temperature, freezing and severe vibration during transportation and storage
Precautions:The product should remain sealed and used as soon as possible after opening. Low-temperature freezing may cause emulsion breaking, stratification or performance degradation.
