Epon® Resin 828 is a standard liquid epoxy resin used in formulation, fabrication, embedding, potting, and resin system development. It is commonly used as a base epoxy resin in applications where cured systems require adhesive, dielectric, and chemical resistance performance when combined with appropriate curing agents.
Synonyms / related names: Bisphenol A diglycidyl ether; bisphenol A-epichlorohydrin polymer; DGEBA epoxy resin.
This resin is supplied for laboratory reagent use and manufacture of substances. When cross-linked or hardened with compatible amine or other epoxy curing agents, cured systems may be used in protective coatings, structural adhesives, encapsulation, and composite-related formulations.
Researchers, formulators, and industrial users commonly use standard bisphenol A epoxy resins for embedding, potting, adhesive development, coatings, and electrical insulation workflows where final performance depends on curing chemistry, formulation additives, and processing conditions.

Applications
Embedding & Potting
Epon® Resin 828 is widely used in embedding and potting applications where epoxy resin systems are selected for cured mechanical, dielectric, and chemical resistance properties.
Epoxy Resin Formulation
This resin may be used as a base epoxy component in formulation work involving compatible curing agents, modifiers, fillers, pigments, and other additives.
Protective Coatings
Bisphenol A epoxy resin systems are commonly used in protective coating formulations for industrial and specialty applications where cured-film durability is required.
Adhesives & Composite Materials
Epon® Resin 828 may be used in adhesive and composite-related formulations where cured bond strength, processing conditions, and final properties are controlled through formulation design.
Compatibility & Formulation Considerations
- Designed for use with compatible epoxy curing agents
- Amine curing agents are commonly used for cross-linking and hardening epoxy systems
- Final cured properties depend on curing agent selection, stoichiometry, additives, temperature, and cure schedule
- Weight per Epoxide should be considered when calculating formulation ratios
Compatibility, cure behavior, and final resin performance should be evaluated under the user’s specific processing and application conditions before scale-up or production use.
Preparation Tips
- Measure resin and curing agents accurately according to the selected formulation
- Mix thoroughly to support uniform cure and consistent final properties
- Minimize contamination from moisture, dust, or incompatible materials
- Consider degassing or controlled processing when air entrapment may affect the final cured article
