In the vast universe of industrial materials, few substances boast the legendary reliability and versatile prowess of epoxy resin. At the heart of countless critical applications, from soaring skyscrapers to the microchips powering our digital world, lies a fundamental, high-performance workhorse: the E51 Epoxy Resin. Synonymous with uncompromising quality, Baling Petrochemical’s E51 (IUMRS Brand) represents the gold standard in bisphenol-A based liquid epoxy resins. And now, with flexible packaging starting from just 1 kilogram, this industrial-grade powerhouse is within reach for pioneering professionals, innovative manufacturers, and meticulous craftsmen alike.
The Epoxy Backbone: A Chemistry of Strength
Epoxy resin is not merely a material; it is a chemical marvel. As a polymer containing multiple reactive epoxy groups, typically synthesized from epichlorohydrin and bisphenol-A, its true potential is unleashed during curing. When combined with a hardening agent, these groups open and cross-link into an immensely dense, three-dimensional network. This transformation from a manageable liquid to an infallible thermosetting solid bestows properties that few other materials can match: exceptional adhesion, formidable mechanical strength, superb chemical resistance, and outstanding electrical insulation. In this esteemed family, the E-51 formulation stands out for its perfect balance of workability and final performance.
Baling Petrochemical’s E51: The Benchmark of Purity and Performance
Product Name: Epoxy Resin E51 (IUMRS Brand)
Model: E-51
Manufacturer: Baling Petrochemical (Made in China)
Key Specification: A high-purity, colorless transparent viscous liquid with 100% solid content.
Baling Petrochemical, a leader in China’s petrochemical sector, produces E51 to exacting standards. Its specifications tell a story of precision-engineered quality:
- Epoxy Equivalent Weight (EEW): 186.2 g/eq – A critical measure indicating resin reactivity, ensuring predictable and consistent cure profiles with various hardeners.
- Viscosity: 12,460 mPa·s – This optimal viscosity offers excellent flow for impregnation and casting while providing sufficient body for coatings and adhesives, minimizing sag.
- Exceptional Purity:
- Color (Gardner): ≤1 – Virtually water-white clarity, essential for applications where aesthetics or UV stability are concerns.
- Hydrolyzable Chloride: 0.0358% – Extremely low ionic impurity content, which is crucial for superior electrical insulation and corrosion resistance.
- Volatiles: 0.020% – Minimizes shrinkage during cure and ensures a dense, void-free final polymer matrix.
This trifecta of low color, low chloride, and low volatiles underscores E51’s status as a premium Industrial Grade resin, trusted for the most demanding environments.
The Unmatched Property Portfolio: Why E51 Reigns Supreme
1. Superior Adhesive Strength & Toughness: E51 forms molecular-level bonds with an extensive range of substrates—metals, concrete, glass, ceramics, and many plastics. Its cured matrix exhibits high cohesive strength, resulting in joints that withstand substantial stress, impact, and fatigue. When formulated as part of a polyurethane-hybrid system, it marries the best of both worlds: the toughness and flexibility of PU with the superior adhesion and chemical resistance of epoxy.
2. Champion of Chemical Resistance: E51’s highly cross-linked, inert structure provides a formidable barrier against a wide spectrum of chemicals. It demonstrates particular excellence in resisting alkalis, making it indispensable for concrete protection, floor coatings in factories, and chemical storage facilities. It also stands strong against acids, solvents, and salts, ensuring long-term asset protection.
3. Premier Electrical Insulator: With its high purity and non-conductive polymer structure, cured E51 resin exhibits excellent dielectric properties, high volume resistivity, and strong arc resistance. This makes it the material of choice for potting and encapsulating sensitive electronic components, transformers, and insulators, shielding them from moisture, dust, and mechanical shock.
4. Versatile Mechanical Properties: From rigid, load-bearing composites to tough, flexible coatings, the mechanical properties of E51 can be finely tuned by selecting the appropriate curing agent. It can produce surfaces with outstanding abrasion resistance, dimensional stability, and durability.

A Creator’s Guide: Crafting with E51
A common formulation for crafts:
Mix Ratio: Resin (Part A) : Standard Epoxy Hardener (Part B) = 3 : 1 by weight.
Procedure:
- Prepare: Ensure all containers, mixing tools, and molds are clean, dry, and dust-free.
- Measure & Mix: Precisely weigh the components. Mix thoroughly for 3-5 minutes, scraping the sides and bottom to ensure a completely homogeneous blend.
- Cast: Pour the mixture into your mold or onto your surface. Use a heat gun or torch to gently pop any surface bubbles.
- Cure: Allow to cure undisturbed on a level surface. Typical cure time: 12-16 hours at 25°C (77°F) to demold; full properties develop over 3-7 days. Cooler temperatures significantly slow the cure.
